Team Fink Borg Episode 2

After listening to Team Fink’s Kim speakers for two years now, and purchasing the review pair, it’s provided the ability to get very familiar with their sound. The quick, spacious, and tonally accurate sound of these 2-ways with their AMT/Heil based tweeter have become a favorite, leaving a number of more expensive speakers collecting dust.

In the midst of waiting for a shot at the larger Borg model, Mr. Karl-Heinz Fink has made updates to the cabinet, crossover, and a slight change to the tweeter, but the woofer remains the same. Not having the chance to hear the originals, a total comparison is not possible, but this speaker is fantastic on so many levels.

With a 10 ohm average (6.5 ohm nominal) impedance, the Borg 2s work equally well with tubes or transistors, and like the Kims, have controls on the rear panel to adjust the extreme low and high frequencies to taste. The LF control is more of a damping control to optimize for tube or solid state amplification which is incredibly handy.

There are six standard cabinet finishes, and our review pair has arrived in the white matte and Nextel steel grey. They all look great and the level of execution is outstanding.

Fink mentions the design challenge of using a 10.25 inch mid/bass driver, crossed over to their AMT tweeter at 1600 Hz, but says the bigger driver is “difficult to forget.” He’s not kidding. These speakers have a tonal body and saturation that offers a unique, musical, and very involving sound. Straight out of the crates they sound fantastic. We’ll have a lot more to report in the April issue, where the Borg 2s will be our cover feature. However, if you’re on the fence, don’t wait for our review. They are worth every bit of the $36,490 asking price. Tell them I sent you.       (US Distributor)   (Manufacturer)

Welcome to Distilled!

Hello and welcome to our new section – Distilled.

We are not abandoning our standard reviews, but for those of you that would like a little more than the canned press releases everyone else is posting, but not sure if you want to make the time investment in a full review, we present the distilled column.

A quick overview of components that will be 200-300 words. No space for blather, pontification, or a lot of “I, Me, Mine” stuff.

We’ll do our best to present a couple of good pics, a link to the full review (if it’s done and you’re so intrigued) and a link to the manufacturer. On occasion, we will even post a purchase link if it makes sense. Please NOTE: we are doing this for your convenience, and these are not sponsored or affiliate links.

Thank you for reading!

Meze Elite Aluminum Headphones

Unboxing the Meze Elite Aluminum headphones while reading all of the design and technical information on their website felt more like I was going over the design brief for this year’s F1 engine package.

No other segment of the audio industry has advanced at the pace of the world’s finest headphone manufacturers. The level of materials selection, machining, and electronics expertise incorporated is beyond incredible, and these top Meze phones are as beautiful to look at as they are to listen to, but by all means go straight for one of your favorite tracks and you’ll be in love.

We’ll have a full review in issue 121, but between the two cables offered (silver and copper) and two different styles of ear cushions (Alcantara or a hybrid Alcantara and leather version) you’ve got four different ways to custom tune the final result. Thanks to their dual coil array, they sound like no other planar headphone. The level of sheer transparency and natural tonality might even have you re-thinking whether you even want speakers anymore. Bass is extended, defined and has just the right amount of damping and control to sound real. Everything from the mids on up to the highest highs is crystal clear, with a stereo image that feels more like your sitting about 10 feet from a pair of huge speakers, than that bowl-like feeling often accompanying the headphone experience.

Finally, the patent-pending suspension wings support system distributes the weight of the Elite phones so well, you can wear them all day with no discomfort. These are definitely one of, if not the most comfortable high-performance phones to come our way. After about an hour, be careful when you get up – it’s so easy to forget you have headphones on, I don’t want you to pull the cord!

There’s so much more we need to tell you about these exciting headphones, but if you just can’t wait – buy a pair. Right now. And be ready for an experience you might not have thought possible with a pair of headphones. (Though we must give some credit to our reference dCS LINA stack.)

A true triumph of technology and aestheticism.


FOCAL Launches the refreshed Aria EVO X Series

Focal presents Aria Evo X, a line of high-fidelity loudspeakers for the home to follow in the footsteps of the Aria 900 range, which has enjoyed a decade of success. With revamped technologies and a brand-new finish, the Aria Evo X loudspeakers step it up another notch in terms of both sound and design. The French brand has developed this new range as a continuation of the Aria philosophy: to deliver a pure listening experience by providing the best loudspeakers in their category.


Aria Evo X pays homage to traditional hi-fi with its collection of five products: one compact bookshelf model (Aria Evo X N°1); three slender floorstanding loudspeakers (N°2, N°3, N°4) and one additional model for an impressive soundstage in a Home Cinema configuration (Aria Evo X Center). Much like the Aria 900 loudspeaker line launched in 2013, Aria Evo X exists to provide high-fidelity audio that is expressive while accessible in relation to the performance it delivers. The line promises sensational listening pleasure, with the brand’s signature immersive experience.


With the benefit of Focal’s sound know-how, the loudspeakers boast outstanding technological innovations that are exclusive to the brand. The ‘M’-shaped inverted dome TAM tweeter, successor of the TNF tweeter. This innovative feature reproduces the treble more faithfully by going further into the high and low ends of the spectrum. The surround on the midrange is equipped with TMD® (Tuned Mass Damper) technology to stabilize how the surround behaves, reducing distortion and delivering perfectly balanced dynamics. The ‘M’ shape of the dome is another Focal innovation, capable of reproducing high frequencies up to 30kHz. In the woofers, meanwhile, the magnet has been revamped to deliver more impact in the bass. Focal’s engineers have also reworked the crossovers with better components to improve loudspeaker balance. Innovation is never just about the technology at Focal. The brand is also offering a new finish: Moss Green High Gloss. With its deep green shade and high gloss varnish, it lends a bright and modern appearance to the loudspeakers. It is joined by the Black High Gloss and Prime Walnut finishes, in all their timeless elegance. Each finish is combined with leather-effect front panels.


The Aria Evo X opens a new chapter for a signature Aria feature, with the iconic flax cone appearing in the line’s midrange and bass speaker drivers. An innovation Focal first unveiled with the Aria 900 line in 2013, this cone made from French flax fiber is used to produce a very natural sound, free of coloration while boasting rich midrange reproduction and clear bass strokes. Manufactured in the Focal workshops, it offers an immersive and dynamic listening experience, reproducing vocals with exquisite clarity and definition. This technology is recognized every year for its remarkable qualities in terms of sound reproduction, and is now a feature in many Focal products, from integrated loudspeakers to car audio kits, and even monitors for sound professionals.


Aria Evo X pricing below with availability February 2024.

  • Aria Evo X N°1 – $2,398 pair
  • Aria Evo X N°2 – $4,798 pair
  • Aria Evo X N°3 – $5,198 pair
  • Aria Evo X N°4 – $5,998 pair
  • Aria Evo X Center – $999

MoFi Distribution introduces the MoFi Electronics MasterDeck Turntable

MoFi Distribution proudly introduces the new MoFi Electronics MasterDeckturntable, a reference grade product designed by master turntable maker Allen Perkins. Created by vinyl lovers for those with the desire to accurately reveal and experience the true music embedded deep in the groves of their vinyl LP collection. The MasterDeck turntable will be manufactured in small batches in the USA at MoFi Electronics’ factory located in Ann Arbor, Michigan to ensure the very highest level of quality control.
A compelling feature of the MasterDeck is an “all new” Dual-pivot carbon-fiber 10 inch tonearm that offers the best balance of precision, control and friction-free tracking. This tonearm uses a removable headshell and allows for the optimization of virtually any cartridge by facilitating  adjustable horizontal angle (azimuth), vertical tracking angle (VTA), overhang and anti-skate. As well, all internal tonearm wiring is provided by Cardas Audio.
The MasterDeck achieves precision playback in part with an optically regulated speed controller using a three-phase brushless DC drive motor, housed in an isolated container. Fine speed adjustments are available for 33, 45 and 78 RPM and are displayed on a four-digit display. The 1.75 inch thick platter is a high mass hybrid material constructed exclusively from Aluminum and Delrin. This platter sits atop an ultra-high quality Encapsulated Spiral Groove inverted bearing. Isolation from both environmental noise and feedback is accomplished by effectively floating the MasterDeck using custom Harmonic Resolution Systems (HRS) Isolation Feet.

The Vera-Fi Vanguard Scout Speakers


Listening to The Knack’s “Africa,” I tried a trick that I’ve seen at more than one hifi show – I hooked this $300 pair of speakers to about $200k worth of gear. Wacky as this seems, it illustrates two things: the ultimate performance envelope of said speakers, and how easy (or not) they are to drive with less than mega components. How many times have you listened to that totally affordable pair of speakers, only to bring them home and find out they sucked?

Guilty as charged, more than once. A high-power amplifier with the ability to deliver a lot of output current can take charge of a mediocre speaker and deliver results that your budget receiver can’t. So, the next step was to bring my vintage Pioneer SX-424 in from the bedroom closet. In case you’re too young to remember this one, it was a 12 watt per channel solid-state model at the bottom of the Pioneer lineup in the 70s. Back when a lot of early solid-state gear sounded dreadful, this low powered receiver was incredibly musical.

Swapping the Pioneer in place still makes for an excellent music experience. This is good news for those of you putting together one of your first system. If you don’t take advantage of Vera-Fi’s holiday special with their Vera-Link portable wireless mono amplifiers that will Velcro on the back of your Vanguard Scouts, you can rest assured they will work well with any budget amplification you can pair them up with. Regardless of amplifier and source choice, you should be able to assemble a really nice music system for $1,000 – $1,500 with the Scouts to anchor things.

The Vanguard Scouts combine a robust cabinet with a 5 ¼” paper cone woofer and a 1” soft dome tweeter. Vera-Fi’s Mark Schifter sent me some pictures of the crossover network, and there’s way more expensive components in this box than you’d ever expect out of a $299 pair of speakers. All good stuff.


I suggest setting the Vanguard Scouts up about 2-3 feet from the rear wall, and found that with the 24” Sound Anchors stands the tweeters were just about ear height. The Vanguard Scouts sound pretty good if you just “throw them in the room,” or put them on a couple of bookshelves. If you put them on top of a bookshelf or table, I highly suggest the ISO Acoustics desktop speaker stands for best results. Just click here to buy a set at Amazon. Again, we are NOT part of the Amazon affiliate program. This is for your convenience. These are the best small stands I’ve used with small speakers, offering a lot of adjustability and isolation.

Getting back to room placement, a good hour carefully fine-tuning room placement will amaze you. If you can start with the Scouts about 6 feet apart and the front baffle 24” from the rear wall and then nudge them about 6-8 inches up and back, you’ll hear the mid bass clean up and the lower bass get stronger. Make smaller adjustments from there, and when you nail the perfect balance, make note. Ditto for distance between the speakers. Move them apart about 6-12 inches at a time until the stereo image just falls apart and it sounds like two separate speakers, and then back till the image forms again. Tweak the toe in for maximum high frequency transparency and you’re done!  You’ll be amazed at how much more music these small monitors can deliver.

The Vanguard Scouts have a listed sensitivity of 84.5db/1-watt and work equally well with modest tube or solid-state power. Equally good results are achieved with the 50wpc T+A Caruso R and the PrimaLuna EVO100 tube integrated, so there’s no limitations there. Tellurium Q Blue II speaker cables make for a great pairing and is an incredible bargain. Your preference will dictate what works best for you. If your musical tastes lean more towards jazz, acoustic music and female vocals, you might dig a tube amp a little more, while those of you more on the rock, hip-hop and techno side of the fence will enjoy the additional bass grip from a solid-state amplifier.

As with any highly resolving small monitor, try to use stands with the most mass you can get and be sure to use blu-tack, or something similar to optimize the interface between stand and cabinet. With speakers this size, every little bit of setup finesse makes a difference.

Further listening

Most listening was done in my main room which is 24 x 36 feet, and these little speakers really put on a great show in a room this size. (Vera-Fi does have a small sub on the way, so stay tuned) Obviously, with room gain, they work incredibly well in a smaller room, and listening in our back bedroom which is 11 x 14 feet was perfection. The quality of the bass delivered might even make you think twice about bothering in a smaller room.

Going off on a prog rock bender, Roon sent me to a great early 70s French band, Ange. Think Yes, King Crimson, and early Roxy Music all in one. Playing dense music fairly loud reveals how well the Vanguard Scouts keep their composure at this level instead of flattening out – you’ll have to push them pretty hard for that, and they give ample warning.

Thanks to a gentle transition between drivers, vocal and acoustic music sounds incredibly natural through these speakers. A wide range of tracks from Aimee Mann to Diamanda Galas all sound convincing. Tone, texture, and timing are also way beyond what you might expect at this price.

Just like the handful of classic small speakers that many of us have enjoyed for decades, the Vanguard Scouts sacrifice extreme frequency extension on the top and bottom of the range, for excellence at what it does handle. I suspect this will keep you happier with said speakers for a lot longer time than something that just grabs you on a quick demo.

In the end…

Much of the internet buzz on these speakers already is in comparison to a few great small speakers like the original Realistic Minimus-7, (and I’ve got a pair of those headed my way on EBay, so we’ll have a video on that soon, as well as a comparison to my vintage A/D/S 400i’s) but the speaker that really came to mind was the Spica TC-50 if you happen to remember those. Of course we still have a pair, but they rarely get played because the tweeters are no longer available and they were very easy to blow.

Thanks to modern drivers, the Scouts seem very robust, and they possess a lot of the soul that this great American mini speaker produced. A tremendous midrange, smooth highs, and mid bass accuracy instead of muddy mid bass, compromised to goose the low end. It’s hard to believe these are only $299/pair. Back when gasoline was $6/gallon, it cost more than this to fill up a Dodge RAM truck! Going further back, the Spica TC-50s were $450/pair.

It’s worth mentioning that a big part of the success of these speakers is the manufacturer direct model. If we were looking at a $20k preamplifier, I’d tell you to stick with something from one of the majors because of a service, support, and resale perspective. But when you’re looking at a $300 pair of speakers from one of the majors, the big manufacturers just can’t do it this inexpensively. By the time dealer and distributor markup is factored in, I’d be shocked if the least expensive B&Ws have more than 20 bucks invested in the drivers and crossover network. It is what it is.

The Vera-Fi Vanguard Scout speakers are a true triumph for music lovers on a tight budget. And with that, I’m going back to the Knack and blasting “Good Girls Don’t.” Highly recommended.

The Focal Vestia no.1 Speakers

After spending an afternoon with staffer Earle’s Focal Sopra 3s, just before firing up their new Vestia no.1 at my place, the level of sonic excellence they bring to a $1,198 pair of speakers seems amazing. Listening to the same handful of tracks that I shuffled through at Earle’s house, not too much sonic memory was lost in the 25-minute drive on the I-5 to my place.

Playing the Vestia no.1s through the main reference system truly shows off what they can do, but it’s not really a fair comparison, so my Naim Uniti Atom ($3,599 and available from your Naim/Focal dealer) makes for a perfect match. However, like all the other Focal speakers we’ve used, they are just as easy to drive with your favorite tube amplifier as well. Swapping the Uniti Atom for the PrimaLuna ProLogue One and the Naim CD5is in for review is equally enticing.

Queuing up a MoFi copy of Santana’s Caravanserai is lovely and room filling. Placed on 24” Sound Anchor stands about 10 feet apart on the 24-foot wall in my listening room (couch about 10 feet back) the small Focals produce a large soundstage, but in a large room, their horizontal dispersion, especially from the top is slightly limited. The cure for this is stands that allow the tweeters to be close to ear height as possible, or the ability to tip them back slightly. The more stylish dedicated stands from Focal do just this, and are reasonably priced, at $249 a pair. Thanks to their front ports, you can achieve nearly the same effect on a bookshelf. The Vestia no. 1 is definitely user friendly.

All in the family

The Vestias take advantage of some new and existing Focal technology. You can read the full story on the Focal website here; suffice to say Focal puts a lot of expertise into their entry level speakers. The only thing that is really compromised between the Vestias and the higher range Focals, is the simplicity of the cabinets. The finish and shape is a more simple box shape, lacking the complex finish of Sopras and Kantas. Yet what is delivered is of top quality. Compare the Vestias to some of the competitors made in China, and you can see the Focal difference. A quick rap on the cabinet reveals solid construction and lack of resonance. Impressive for this price point.

A two-way design, the compact cabinet only measures 8 5/8 x10 1/4×15 1/4″ (21.9x26x38.7cm) and weighs only 15.4 pounds, so they are easy to unbox and install. They utilize a 1-inch inverted dome tweeter with Focal’s TAM material. (aluminum and magnesium composite) The 6 1/2- inch woofer is made from recycled carbon fiber, allowing added stiffness at a lower cost than standard, woven carbon fiber – a very unique approach. The Vestias are available in light wood like our review samples, dark wood and a black high gloss finish. All feature a “leather effect” front panel.

Further listening

Moving on to Lloyd Cole’s new album, On Pain (as well as a few LC classic tracks) reveals the clean, natural midrange the Vestias deliver, which ironically hits me near the middle of the third track, “I Can Hear Everything.” Sometimes the soundtrack of your life is synergistic. Going through the gamut of favorite vocal tracks confirms the initial excitement. The Undertones’ “More Songs About Chocolate and Girls” demonstrates the Vestias ability to pull detail from dense, compressed recordings. This is a terrible sounding (but fun) track, showing you can have high end speakers that play everything with ease.

When you’re starting to build a system, every bit of performance you can get for the dollar is key and this is what makes the Vestias such a great value. If you could see what goes on every day at the Focal factory in France, it’s easy to see how they do it. Focal performs every aspect of design and manufacturing in-house; cabinets, crossovers, and drivers. The level of engineering talent is incredible, equally so with execution. Focal definitely takes the high road on the Vestia no.1 in terms of overall balance. Many speakers in this price range hinge their reputation on a single feature, where the Vestias sacrifice an over exaggerated frequency response to deliver smooth and resolving sound.

Changing program material to bass heavy tracks from Thievery Corporation, Massive Attack, and Tosca reveal that the Vestias manage to go down fairly low, and the bass that is delivered is of high tonal quality. Moving them back into a more appropriate sized room (12 x 18 feet, and 10 x 12 feet respectively) and taking care to place them so they can take advantage of a bit of room gain provides tremendous sonic rewards. It’s easy to hear the lineage all the way up to the Utopia series here.

Different partners

Swapping the Naim Atom for the T+A Caruso R, and PrimaLuna amplifier is fun, and again proves that these little speakers have more than enough resolution to discern distinct differences between amplification and program sources.

The no.1s are a great way to start building a system, and like some of the other Focal speakers, they offer a full range of floorstanding speakers, and a center channel option so you can build a multichannel system having the same voice.

Focal claims a sensitivity of 89dB/1-Watt, and they proved easy to drive even with our 12 Watt per channel Lab 12 Mighty (vacuum tubes) amplifier, so they should work well with whatever you have on hand. Around back is a single pair of 5-way binding posts to make connection to your speaker cables equally easy.

At present, Focal does not offer a subwoofer in the Vestia lineup, but they do suggest their SUB600P, for those wanting to keep it all Focal.­ To get a better chance of what they can do in a 2.1 system, they were mated to an SVS 3000 Micro ($899) subwoofer and alternately with a REL T5/x ($699). Thanks to the solid bass foundation that the Vestias deliver, adding a sub makes for a great full range system should you so desire to take this direction.

Constant innovation, tremendous value While some of the names might be a little confusing at times, Focal continues to innovate and apply new technologies and construction techniques on every speaker in their range. That their commitment to excellence is just as serious with the Vestias as it is with their top range Utopia speakers is great news for the beginning audiophile. We are happy to give these one of our Exceptional Value Awards for 2023. This is a great pair of speakers to build a system with.

YG Acoustics Hailey 3

One of the most compelling things about the world’s finest products, be it speakers, watches, cameras, you name it – is the ease of enjoying them in a fashion that you no longer think about the object in use.

There’s no more longing for additional performance, or an aspect of use that annoys you. A Rolex Submariner, a Leica M6 (if you’re a film person) or M10 (if you aren’t), the Eames Lounge Chair (a real one), or a late 80s 3.2 Porsche Carrera. I’m sure you have your own list, but this is where I place the Baileys. The level of performance they deliver is something I doubt you will ever tire of.

This was a more difficult review to write than most, only because the Haileys deliver such an immersive experience that hours pass between paragraphs. Some high performance loudspeakers make for dynamic demos, and that’s great for the 30 seconds you catch of Nils Lofgren’s plucky guitar opening to “Keith Don’t Go,” but then lose their luster during extended listening. The Haileys sail through all the prerequisite audiophile test tracks, but at the end of the day are incredibly musical in a way that you do not want to leave the listening chair for anything more than to change the record.

Thanks to all the new technology implemented at YG over the last few years, much of this effortlessness comes from the low distortion and careful attention to maximizing phase coherence in the recent models. YG claims no more than + /- 5 degrees of phase shift, which is tight indeed. Many studies backup the idea that the human ear is more sensitive to phase anomalies than anything else. Again, this is a major contributor to the effortless presentation these speakers deliver.

Even though the new speakers look very similar to the originals from an aesthetic perspective, every aspect has been re-examined, reconfigured, and redesigned. Even the printed circuit board used for the crossover network is CNC machined in the YG factory. The new models use 3.lmm-thick electrically non-reactive sheets of a secret material mated to pure copper – twice as much copper as in previous YG crossovers and four times the industry standard – and they machine out the copper they don’t use.

No one pays this close attention to fine detail. YG’s Duncan Taylor smiles as he says “that’s our biggest marketing challenge, to let potential customers know how much of an improvement the new speakers truly are.” Yet if you are familiar with the original YG speakers, you’ll hear it immediately.

Top of the list

Listening to Trey Gunn and Tu-ners newest release T-1 Contact Information is a prog excursion full of atmospheric sounds, blazing riffs, and of course killer bass lines. The Hailey 3s do an amazing job creating a massive soundfield with incredible coherence feeling more like a great surround setup, or perhaps the enormous 9-foot-tall Sound Labs ESLs. (But with way more transient ability) One of the Hailey’s main strengths is the integration of the drivers feeling like one big full range speaker. That’s only part of the story.

Taylor explains to me that this speaker is one of the latest models that is filled with “new tech and engineering, with few remnants of the original YG products.” Where the initial YG speakers were incredibly resolving, they required perfection in room treatment and music quality, and to some they brought a fatigue with them that made for short listening sessions. Today at YG, those traits are a thing of the past. Forget everything you think you know about these speakers – though they have similar physical shapes these all new models are a pinnacle of loudspeaker design.

If you are looking for a pair of speakers offering high resolution and low distortion (make that extremely low distortion) without ever feeling harsh, and you value tonal accuracy – YG should be at the top of your list.

The 200-pound (each) Hailey 3 speakers are a three-way passive speaker, taking up a small footprint, relatively speaking, at 13 inches wide and 21 inches deep at the bottom, gently tapering up to 8 inches wide and 16 inches deep at the top. Silver and black anodized aluminum are the standard finishes, but customization is something YG is testing and plans to eventually offer. While visiting the YG factory earlier thisyear, there were some custom-finish speakers on their way to a client that were absolutely stunning.

The surface of a YG speaker surpasses even what I’ve seen in the world’s finest automobiles. Yep, they are that good. These speakers define understated elegance, and more than one friend that has always been “metal speaker” adverse, loved the look, feel, and finish of the Hailey 3s. They will look at home in any decor.

The precision metalwork doesn’t end there. YG painstakingly machines the rigid, well damped cones of their drivers in their facility too. It’s one thing to see the YG’s being made, and quite another to run your hands across the surface of a YG speaker. As a crazed car guy fascinated by machining excellence I have a major appreciation for things built like this.

YG uses a soft-dome tweeter, placing a structure under the dome that they call “the lattice,” which machined from solid aluminum just like the cones of the midrange and woofers. Duncan tells me that nearly 99% solid block is machined away from the individual billet to produce them. Those of you concerned about the environmental aspect of this process, fear not. Every speck of unwanted material is recycled at the YG factory. These cones are a work of art.

Simple setup

For speakers weighing over 200 pounds each, the Hailey’s can actually be set up by one person. While the review pair arrived in road cases, YG sends their speakers in a bespoke crate, so you can bring the container to your listening room, tip it up, and slide the Hailey’s out. These are one of the easiest pairs of large speakers to unpack that I’ve encountered, underlining the thought process behind every aspect of the YG’s design. The spiked feet come with stainless spike cups, so you can adapt them to any flooring situation.

Even with random placement in the 24 x 36-foot listening room (on the short wall) about 12 feet apart and about five feet from the rear wall, the Haileys paint an enormous soundstage. Fortunately, Duncan was kind enough to stop by for the day and fine-tune them to perfection. For stacking those who the see this as the manufacturer stacking the deck in their favor, I always prefer this. Especially with a speaker that I have precious little review experience with. It’s always helpful to the review process when a manufacturer can either tweak the final setup or reassure you that all is well. That way the evaluation can start on an easy note. 30 minutes later, the Haileys are placed to perfection by moving them a bit wider apart and serious listening can begin.

The highly revealing nature of the Haileys 3s is further emphasized during the setup process, when it was time to attach the jumpers between the three sets of binding posts on the rear of the speakers. (As a side note, my demo pair was tri-amp-capable, something YG now offers in addition to the standard single binding post arrangement, though they suspect most customers will probably go with the single set of binding posts.) For this review, Cardas Audio provided a custom set of jumpers from Cardas Clear cable, because I use Clear in my main system. I suggest this with any speaker that you choose to use jumpers with – I have always achieved the best results combining jumpers made from the same cable as the main speaker cables. Taylor tells me that internally, YGs are wired with the exact same Cardas wire, so this makes perfect sense. I’ve never heard a speaker affected by six inches of wire as much as I did with the Hailey 3s.

The speakers arrived a day before the jumpers, so during the initial listening, some zip cord was pressed into use. Not good. At first, it was suspected that the speakers needed more run the in time, but the following day when the Cardas jumpers arrived, this became an entirely different movie indeed.

Articulate bass

Being used to a six-pack of REL subwoofers makes it easy to become spoiled for low­frequency response that is accurate, powerful, and defined. There are many large speakers that can reproduce tones down to 30 or even 25Hz, but the level of low-frequency resolution actually delivered (as with a number of subwoofers, too) is questionable. Moving air is one dimension, but being able to hear Jaco Pastorius’ fingers pluck the strings, with the resulting harmonic structure intact is quite another.

Even though the Haileys can’t move as much air as a six pack of REL’s they do achieve a level of low-frequency resolution and detail that is on the same level and this is indeed rare. We all have different goals concerning low frequency response. My personal bias here is resolution over sheer weight, yours may be different. In addition the YGs bring a wide dynamic range to the listening experience and the ability to deliver high resolution at low listening levels. This is a true display of high performance.

Swapping the Pass XA200.8 monoblocks, for the 15 watt per channel ampsandsound Bryce monoblocks is equally enticing. Even at a one-watt level, these speakers are able to deliver deep, rich, and detailed low frequencies. It’s worth mentioning the Bryce amplifiers deliver tremendous bass response, but that’s a subject of another review. The way these speakers can capture leading and trailing transients on drums and bass guitar is so realistic, you might beshocked hearing it for the first time. In a good way of course.

At least eight or nine different amplifiers from the 3 watt Coincident SETs to the 600 watt per channel PS Audio BHK 600 Monos (tube and solid-state) were used while evaluating the Hailey3s. The common thread here is quality. Because of the resolving nature of the YGs, they will reveal every source component, cable, and vibration control device in your system – though not mercilessly. To get the most these speakers can deliver, I do suggest the best cables and components that you can pair them with.

While some are quick to tell you to spend this much on cable, no more than this on amplifiers or speakers, the YGs are certainly a speaker you can splurge on now as your anchor, and make the other upgrades as time and budget allow. I can’t imagine the YGs would ever be the weak link in your system.


Way too many high-performance speakers, especially those with the ability to play very loud,don’t always integrate the low, mid, and high frequencies in a way that feels natural and convincing. Precious few of the world’s top speakers are able to do this, and nearly all the ones I’ve heard are considerably more expensive than the Haileys. This is the result of a number of things, all equally important.

YG prides themselves on their extensive research in the area of design depth and computer modeling to implement their crossovers. They even build their own printed circuit boards from scratch, with no 90-degree corners in the PC board traces. They are CNC machined in-house from raw board blanks that are made specifically for YG. Components are selected and tolerances meticulously matched before extensive listening tests verify what’s been done on the design table.

The crossover is one part of the equation, yet having custom drivers that work in as close to perfect harmony as possible is the other part. Some manufacturers choose to take a different approach, employing more complex crossover networks to achieve their goals with lower quality drivers. Taking the latter approach does not always make for the ultimate in a smooth transition between drivers, and that last bit of clarity that only the finest loudspeakers can deliver. The YG Haileys are more than deserving of being in that exclusive realm.

That seamless clarity that the Haileys deliver offers a musical experience that is not only realistic, but non fatiguing. These are speakers that you can listen to all day at any volume level and never tire of. That’s the highest compliment I can pay them.

The rest of the range

Great as everything else is, these speakers are equally smooth throughout the frequency spectrum. Those of you that enjoy this aspect of single driver or panel speakers will appreciate how well the three drivers in the Hailey’s work together. No matter how loud or soft the Haleys are played, they deliver the electrical impulses presented to them with one voice.

If you really want to blast the system, you will need more than 15 watts per channel, and though the Haileys reveal a lot at low volume, they are glorious when being played loud. Whether you’re listening to Deep Purple’s Made in Japan, The 1812 Overture, or grooving on some Slowdive, these speakers will take you anywhere you want to go.

Ironically when YG hit the market 21 years ago, under their original ownership they claimed to be the “world’s greatest loudspeaker.” While I can’t make that claim about any one loudspeaker, I’d certainly say that today, YG is in that small top tier of the world’s finest speakers without hesitation.

Teenage Engineering OB-4

Portable music for those on-the-go

By Rob Johnson

I still remember my first stereo, a 1981 Sony Boom box, which served as a loyal companion from middle school through college. It finally failed after a decade of use. However, my nostalgia for the old-school portable form factor persists. So, I’m thrilled to see Teenage Engineering, a Sweden-based company, bring back the classic handle-topped design in a smaller and lighter package with sleek aesthetics and modern technology under the hood. While the company’s name might conjure an image of whimsical product designers, make no mistake. The OB-4 is a sturdy and very capable audio companion.

The Teenage Engineering (TE) OB-4 measures a compact 9.2 x 11.2 x 2.3 inches (233 x 284 x 58 mm) and weighs in at a scant 3.75 lbs (1.7 kg). It contains a rechargeable battery that makes it easy to take your tunes anywhere you go. Driven at high volume via a Bluetooth connection a listener can expect about eight hours of playback. However, low radio volumes will provide a couple days of music before a needed re-charge. Rotated backward, the OB-4’s handle can support it in a reclined position making it equally at home on a countertop, the floor, a driveway, or on a stump next to a camping tent. TE even offers a customized OB-4 backpack with a mesh front, sold separately.

Fun Features

OB-4 offers a choice of three input sources: a 3.5mm stereo mini-jack, a built-in FM radio, and a Bluetooth connection. On the top panel, the OB-4 has a very streamlined user interface with a minimal number of buttons and dials. Depending on the source, control buttons serve different purposes. An owner can also download a basic “Ortho” remote control app for Apple and Android devices. Those who want a dedicated, hands-on remote can purchase the cool-looking, circular “Ortho” remote from TE’s website.

For FM listeners using the OB-4’s buttons, picking a station is easy. Simply push the “play” button to scan for available stations until a tiny LED screen confirms the correct destination. Holding down the “input” button and tapping the “play” reverses the scanning direction. The TE’s handle comes equipped with a built-in antenna. However, to assist in reception-challenged locations, a secondary, removable antenna proves handy. One end of that coiled antenna has a hook to facilitate connecting it to a window blind or even a nearby tree branch for better reception. That supplemental antenna can store neatly in the OB-4’s handle or removed entirely when not needed.

Those wanting to hear device-streamed or stored music will enjoy the simplicity of the Bluetooth source option. Once connected to the OB-4, the phone’s volume buttons control the TE’s volume knob. The OB-4 sounds marvelous with any music thrown at it. However, a user cannot stream high-resolution music that exceeds Bluetooth’s capability. Some might prefer using the OB-4’s 3.5mm stereo input.

The OB-4 offers another music source option that requires some explaining. While the unit does not feature line-outs for external recording, it does have a fun, partial workaround built in. As music plays, it’s captured by a two-hour, constantly-rolling digital “tape” recording. After two hours, “old” music starts to disappear, replaced by new. A tiny wheel on the OB-4’s top edge physically spins while the recording process takes place. It’s both humorous and beguiling to watch the process in action. Anytime a listener wants to revisit the past, spin the wheel counterclockwise to hear previously enjoyed music. The opposite action moves a listener forward until they catch up with real-time sources. It’s irresistible to play with the controller, even if it’s just a quick spin now and then. While a user twists the wheel, there’s an old-school DJ “record-scratching” sound. When the wheel stops moving, cached music resumes playback from that point.

The OB-4 has other quirky features, too. The OB-4 has a built-in metronome, a Yoga Mantra setting, and some ambient sounds which – as I’ve discovered – do a great job of encouraging sleep. Be sure to check out the OB-4 manual for more details on ways to loop music and more.

Super sonics

The OB-4 may be small, but the TE team managed to squeeze in two tiny tweeters, a pair of 2.5-inch midrange drivers, a bass port on the lower left side, and a 38-watt-per-channel amplifier. The midrange cones’ position, one-third the way down the OB-4’s front, makes them look like giant owl eyes. It’s endearing, but don’t underestimate those little things! They manage to push forth a surprisingly loud, clear, and detailed sound.

Unlike the tweeters, the midranges do not have protective grilles over them. While they recess slightly into the OB-4’s body, the potential vulnerability is still a little anxiety-provoking. The OB-4 is designed for portability, but there’s a very real possibility of a dented cone if the owner gets overly cavalier and tosses the OB-4 into a car trunk or bag.

The OB-4’s specifications suggest low-frequency reproduction in the 52Hz range. There’s a caveat to the TE’s bass prowess, though. As with large stereo speakers at home, placement is critical. If positioned too close to a rear wall bass boominess can result. If too far from the wall, the bass can disappear. As a portable stereo, it’s easy to position the OB-4 anywhere needed to find the perfect Goldilocks zone. When in a room’s corner or near a rear wall, natural bass loading kicks in. So, in a way, the TE offers an ultra-manual tone control. Find the sonic balance that works best for you.

Nobody should expect the OB-4 to exceed the high-resolution sonics or stereo imaging capability of a good component system because it is not designed to. But despite the inherent limitations of a boom box form factor, the OB-4 does a great job of delivering the musical goods. Sound-wise, it strikes an excellent tonal balance with slightly warm, stridency-free playback even at high volumes.

Summing up

Three close friends own and use their OB-4s regularly. The boxes move around the house to deliver music anywhere it’s needed. When we rent a vacation house together, there’s always an OB-4 playing non-stop. An OB-4 also joined our trip overseas and enhanced our downtime with music wherever we went. While other small, single-purpose Bluetooth speakers may be less expensive and easier to carry around, I’ve encountered few that approach the OB-4’s musical presence.

At $649, Teenage Engineering’s mini stereo isn’t cheap, but it does not sound or feel cheap either. The OB-4 is a durable and creatively purpose-built device that reimagines the classic boom box style with a modern twist and unique features. Those who enjoy sound on-the-go will find their OB-4 a marvelous complement to their home audio system — or even as a one-box primary listening device. It’s a worthwhile investment for those who enjoy great sound anywhere.

Teenage Engineering also produces several other products including electronic musical instruments and even a tiny turntable kit that lets its owner cut their own one-song records. Check ‘em out here.

REVIEW: The Emerald Physics 600.2 SE Amplifier

Driving a pair of vintage Acoustat 2+2 full range electrostatics to panel rattling volume while listening to the new Stones album, the yellow circular power output meters on the 600.2SE power amplifier are barely bouncing mid-way up the scale. Staying in the 80s groove with a couple of tracks from Cameo (“Word Up” and “Single Life”) push the power meters go all the way up, but the stats are in serious damage of being blown up. Swapping speakers for the current Martin Logan ESL9s in for review, with their dynamic woofers take full advantage of 600 watts per channel.

You heard right, 600 watts per channel in a nice compact chassis that is about 17 inches wide, 14 deep, and just over 4 inches high, weighing about 15 pounds. The matte black finish is punctuated by a power switch, those power output meters, and a tube/solid-state switch for the buffer stage. It’s the essence of simplicity, and bravo to the EP team for not making the logo as big as the box.

Plenty of power on tap means no speakers are off limits. Auditioning the 600.2SE with about a dozen pair of speakers from the inefficient Acoustats, a pair of Magnepan 1.7s, some Harbeth speakers (easy to drive but relatively inefficient) as well as the YG Acoustics Hailey 3s ($63,800/pair) and Peak Consult Sinfonias ($55,000/pair) it was easy to find the performance envelope. Ultimately, most of the critical listening was done with the Martin/Logan ESL 9s, a vintage Levinson no.36 preamplifier, and the Naim CD5si disc player. Some streaming was done with the dCS LINA, for Qobuz and Tidal tracks.

Super simple setup

The 600.2SE arrives with a pair of ECC88 tubes already installed, which are used as a buffer stage. That switch on the front panel gives you the option of using a solid-state buffer, featuring a pair of high-quality Texas Instruments OPA 1637 fully balanced driver op amps. These or the ECC88s in tube mode deliver a fully balanced signal to the 1200SA2 ICE power amps. Designer Dr. Viet Nguyen makes it clear “that no transformers are used to achieve balanced operation, this is a full balanced amplifier.”

He also goes on to mention that though the RCA and XLR inputs are switched automatically by an internal relay, the amplifier favors XLR, and will switch to XLRs when installed. This also protects the amplifier from both sets of inputs being active at once.

The ability to switch gain internally between 0dB, 6dB, 14dB, and 20dB. Set at 6dB from the factory, this combines with the 22dB gain of the ICE modules for 28dB overall. As my Levinson preamplifier has substantial gain, removing the top and resetting to 0dB keeps the no.36 in its sweet spot longer. It also allows for a longer range of volume control. Should any of you be using a passive linestage/attenuator, you may even take advantage of the higher gain settings, especially if you have inefficient speakers. EP gets an A+ on this level of versatility.

The 600.2SE sounds excellent out of the box, requiring no more than 24 hours of constant play to being all it can be. As with any component, decent cables will add a bit more to the presentation, but you don’t have to go nuts. With some Audience StudioTwo cables in for review, this makes a perfect combination, offering high performance, and doesn’t break the piggy bank.

The sound

As mentioned, Class-D amplifiers are continually improving, but specs aren’t everything. This amplifier delivers a high level of musical involvement, not just high power. On many levels, Class D is turning into a “best of nearly everything” way to deliver the goods, because dynamic range is just as important as the other factors that music lovers and audiophiles enjoy. Recently I’ve had the chance to listen to a couple of incredible amplifiers that only deliver 25 watts per channel, and sometimes you just need the power.

Yet when listening to acoustic music, the 600.2SE still offers plenty of delicacy – especially when compared to a lot of other amplifiers that are similarly (or higher) priced. Tracking through the usual favorites reveals an amplifier that does an excellent job rendering acoustic guitars, female vocals and percussion instruments, which leads us to that switch on the front.

Much like my PrimaLuna EVO 400 tube amplifier, that offers triode and ultralinear mode, switching between the tube and solid-state buffer stages gives the 600.2SE two distinct personalities. Think of the solid-state section as “just the facts,” and the tube section as a kinder, gentler presentation. You might prefer one overall, or perhaps use the tube section when listening at lower volumes in a more acoustic/female vocal mode. It’s plenty of fun to experiment with, and you might even want to jump off the cliff and get a great pair of vintage NOS ECC88s to go further down that path.

If Class D amplifiers excel at anything, it’s bass extension and grip. Most subwoofer companies use massive Class D amplifiers, so that’s a clue. Listening to a long playlist of bass heavy tracks instantly showcases this aspect of the 600.2SE.  If you love house, hip-hop, electronica and the like, this is an amplifier to raise the roof with. Even with the panels, the level of control and extension this amplifier provides is indeed impressive.

Similarly speaking, the one area of musicality that Class D amplifiers fall down on a bit, is the ability to provide a massive soundstage in all three dimensions. But again, A: we’re talking about a $2,500 power amplifier (and nobody’s $2,500 amp produces a massive 3D soundstage) and B: you have 600 watts per channel. Dynamics are the fourth dimension, so what the 600.2SE lacks in soundstaging abilities, it more than gives back in dynamic contrast. If you really want to cheat this, put your paws on a nice, vintage, all-tube preamplifier. Switching the 600.2SE back to all solid-state and swapping the Levinson for the PrimaLuna EVO 100 preamplifier, or a vintage ARC SP-3 gives a lot of that back. Remember, audio is a journey.

A definite winner

Class D amplifiers keep improving across the board, and you ignore them at your own peril, especially if you’re trying to create a powerful system on a tight budget. The Emerald Physics 600.2SE is the perfect example. Taking advantage of a small company profile, efficient manufacturing overseas, and going dealer direct, makes for high value and high performance for $2,500. In typical Underwood HiFi fashion, they are “introductory pricing” the 600.2SE at $1,999 until they don’t feel like it anymore, so perhaps buy yourself an early holiday present and take advantage of the savings?

As the anchor of a high performance, reasonably priced system, the Emerald Physics 600.2SE has nothing but check marks in the positive column. And is more than worthy of one of our Exceptional Value Awards for 2023. You might even say really exceptional value. Tell them we sent you! Please click here to go directly to the Underwood site.

FULL REVIEW: Enleum AMP-23R Amplifier

If you happen to be an audio enthusiast that is only impressed with large racks of gear, and convinced this is the only way to go, skip this review. You won’t want the Enleum AMP-23R. It’s small. Tiny, actually. Like 9 inches square and a little over 3 inches tall with super cool feet attached. I’ve seen bigger apple pies than this.

In all seriousness, it has about the same footprint as a Nagra Classic component and is half the height. Listening to the Chemical Brothers “Live Again,” the amount of bass at my command is staggering, controlled, and well defined – as listening to the Chemical Brothers should be. The rest of the frequency spectrum is equally well rendered.

For the rest of you, this amplifier is so special, there’s no real cliché to describe it. Often, as you go up the range of the world’s finest components, they reveal more music – more resolution, less noise, more dynamics, more of their core voice. What if you could have a modest helping (i.e. 25 watts worth) of “as good as it gets” sound for $6,250? That’s the Enleum AMP-23R. After a lot of listening comparisons, it stacks up with the finest gear.

At first, the thought of adding another great, low-powered amplifier to work with some of the high sensitivity speakers we’ve been reviewing, and keeping the hours low on my 300Bs was appealing. However, the minute the AMP-23R was connected up to the Peak Consult Sinfonias ($55k/pair) in place of the C-J ART88/PS Audio BHK600 monos powering them for some initial run in, the AMP-23R is non stop excitement. Running through track after track of music that’s been our review staples for 20 years, the AMP-23R turns in an incredible performance.

So intrigued with this, moving the AMP-23R over to the YG Hailey 3s ($67,000/pair) with a similar sensitivity, but different tonality than the Peaks, and even slightly more resolving, this little amplifier delivers an equally engaging performance. In both instances the source component is the dCS Vivaldi ONE. This is the point in the review, where excuses are made that the review component, only a fraction of the cost of the mega gear in said reference system really doesn’t measure up. Nope. Not here. Of course, the Enleum amplifier will not drive the Peaks or the Haileys to the same level as the big Pass or big PS monoblocks.

The sheer quality of musical experience delivered by the AMP-23R at reasonable volume levels is as good as it gets. (with modest efficiency speakers.)

The only reason I mention the cost of the first two speakers used with the AMP-23R is to illustrate the level of resolution it is capable of – and that it does not sound out of context in a 200k system. Hiding it in the rack when a few friends visited made it a lot of fun to play tricks with them. No one could believe this small amplifier could deliver such an exciting performance!

A fantastic partner for high sensitivity speakers

Installing a pair of efficient speakers is an even more amazing experience. If you’ve always liked horns, or other high sensitivity speakers, but still hold a bit of trepidation about SET amplifiers, the AMP-23R will surprise you in a very good way.

The relatively high impedance of most SET amplifiers makes them slightly more speaker sensitive than other amplifiers, and it’s usually the bass response that takes a hit, combined with their low damping factor, there aren’t many SETs with true bass grip. (Though we have had excellent results with Nagra, ampsandsound, and WAVAC, but these are all much more expensive than the Enleum)

Swapping speakers for the Heretic AD612s (98dB/1-watt), and the new Zu Audio DWXs (95dB/1-watt) both make the AMP-23Rs 25 watts per channel into 8 ohms (45 watts into 4 ohms) seem like way more power than you’d ever need. Even with the higher impedance Zu and Heretics, the AMP-23R never runs out of power.

More listening

Every bit of music selected was a wonderful experience through the AMP-23R. No matter what you enjoy, I think you will be fulfilled. The amplifier possesses a prodigious level of pace and timing. When listening to the usual Blue Note favorites, every player is locked down and does not waver. Tracking through Herbie Hancock’s Main Title theme to Blow Up, the drums are planted at the rear of the soundstage, as Freddie Hubbard’s horn comes in over Hancock’s piano.

Female vocal lovers just might think they are listening to an SET, because of the sheer delicacy this amplifier portrays the human voice. Whether I was listening to Chrissie Hynde, Christine Mc Vie, or Christina Aguilera, every subtle nuance of their voices came through with spectacular feel.

Transient response is also excellent, with no sense of fog, cloudiness, or overhang. Drum heavy music (take your pick) is refreshingly open and punchy. This contributes heavily to a complete lack of fatigue when listening for hours on end. Finally, the sound field created is immense in all three directions, yet the AMP-23R allows music to scale up and down with ease, and it sounds fantastic at very low volume levels as well. Zero complaints here.

A few comparisons

With a couple of great single ended and low powered tube amplifiers on hand to drive the Zu and Heretic speakers, it made sense to undertake some A/B comparisons. To be fair, the $24k pair of ampsandsound Bryce monoblocks deliver slightly more midrange magic and a bit larger overall soundstage. The Pass First Watt SIT-3 offers a bit more organic, warmer presentation, and the Pass INT-25 even warmer still. The Coincident Frankenstein amplifier with WE 300Bs also gives a bit more bloom, but it is in a fun, saturated way.

Except for the Pass INT-25, all of these are more expensive, power amplifiers only, and delivered the performance they did with the $38,000 Pass XS Preamplifier driving them. And tubes are tubes. Sometimes more glorious, but always needing replacement. The Pass INT-25 is more expensive, much larger, and much heavier, with a different tonality.

The point here is not to show any disrespect for the other players, but to again underline just how good the AMP-23R is. 

The Enleum difference

There have been a handful of great phono preamplifiers that operate in current mode, providing a tremendously transparent view of the music. The AMP-23R works this way as well, and the volume control varies the amplifier’s gain, instead of merely attenuating the input. Peaking inside, reveals a pair of Ensense gain modules and a single pair of output transistors bolted to the chassis as a heat sink. Please note, the Ensense modules use all discrete transistors, and no negative feedback. Taking the circuit further, Enleum’s JET2 Bias circuit works in real time to constantly monitor (and correct as needed) each pair of EXICON MOSFETS that make up the output stage.

The stark, yet highly fashionable casework takes the same approach as the circuit design. Ergonomics are top notch, and the machining quality is both tasteful and superb. Even the carefully designed trio of vibration controlling feet work with the mechanical design to keep a minimum of mechanical noise from entering the circuit board.

Around back is a pair of analog RCA inputs marked “Voltage.” These are traditional analog inputs, and the pair of BNC inputs in between them are marked “Enlink,” which are reserved for future Enleum products to work in current mode. (hopefully, a phono stage and matching DAC?) Finally, a small but efficient remote takes care of controlling things from your listening position.

A winning combination

The AMP-23R does everything right. No make that perfectly. In the couple of months that it’s been here, it’s literally a freak out every time we use it. And it’s been so much fun to have audiophile buddies visit with the AMP-23R playing on top of a rack full of massive gear and walk up to turn the level up on this tiny box. Surprise all around, and that’s a great thing.

I’d suggest a 90db/1-watt pair of speakers if you really need serious volume levels, but with the level of musical information that the Enleum 23R reveals, there isn’t a set of speakers under $100k a pair I wouldn’t connect it to. And it’s a killer headphone amplifier too. A quick email to Enleum reveals that the headphone jack is connected directly to the output stage, so it takes full advantage of the circuit, unlike so many integrated amplifiers that tack on a simple op-amp circuit as an afterthought.

Using the Focal Utopia 2022s for reference listening again shows off just how musical and resolving the AMP-23R is. Theoretically, you could buy this amplifier for headphone use only and still feel like you got a good deal.


They say that a true master knows where to pound the nail. I submit the founder of Enleum, Soo In Chae, is in the league of the true masters. The final measure of a top-quality product is the way every aspect of said product is realized. In addition to class A+ sound, this amplifier is wonderfully crafted, and finished to perfection. It is as much a joy to physically interact with and use as it is to listen to.

This amplifier more than deserves to sit on the same shelf with the world’s finest gear. I’ve purchased the review sample, and it will be doing just that here for years to come. I anxiously await what Enleum will bring to market next.

AMG V12 Turntable

Being an enthusiast of great industrial and mechanical design, I hold objects that perform as well as they look in the highest esteem.  I confess to becoming an admirer of the AMG V12 the second I saw pictures of it.  When I saw the V12 in person, had I been sitting on an analysts couch, performing a word-association drill, Leica would have been the first word that came to mind.  Imagine, those of you who own or have owned a Leica (or an older 500-series mechanical Hasselblad), that the camera maker decided to enter the turntable business and bring its level of machining expertise to turntable design.

But craftsmanship from a brand like Leica goes so far beyond simple aesthetics.  How would a turntable manufacturer translate the damped feel of a Leica focusing mechanism, or the positive engagement of a Ferrari gearshift, or the vault-like sound that a Rolls Royce door makes to the language of turntable design?  Germany’s AMG (for Analog Manufaktur Germany; no relation to the Mercedes-Benz design branch by the same initials) puts the same level of artistry into its V12 turntable.  Its design allows users to operate the capacitance-controlled power and speed switches and feel the effortlessness of the tonearm, while the uniformity of its machined and anodized surfaces provide a visual package as stunning as the turntable’s performance,

At $16,500, a cost which includes the wooden base and 12-inch AMG tonearm, the V12 achieves price parity with its peers from AVID, Clearaudio, SME and others.  During a conversation with AMG designer and principal Werner Röschlau at the Munich High-End back in May, I learned of the high level of refinement that the V12 offers and that this is not really his first attempt at building a turntable.  Röschlau, who is an engineer by trade, did high-precision machine work for a few top turntable manufacturers for over a decade.  Along with his own design expertise, Röschlau applied what he learned working for those manufacturers to the V12.

This turntable is the epitome of simplicity in look and operation.  Röschlau tells me that every aspect of the tables’ design revolves around simplicity, functionality and longevity.  “I truly hope that these turntables outlive me,” he says with a smile.

Sharpen Your Skills

The V12 offers an amazing combination of weight, stability and delicacy.  The SME arms that I use on a number of tables feel thick and clunky compared to the V12 arm (though the former are easier to adjust at first).  Again, the comparison to a Leica comes to mind with the V12, as I reflect on the turntable’s small, lightweight, minimalist controls that make perfect sense once you get used to them.

It’s often said that people who are masters of their craft make things look deceptively easy.  Sitting at home watching Sebastian Vettel win the F1 championship, you think, “How hard can it be? I can drive a car.”  I was thinking the same thing, as Garth Leerer, the US importer for Musical Surroundings, fine-tuned this table.

But this tonearm does not invite constant fiddling like a Tri-Planar does; the V12 arm is perfect for someone who sees turntable setup as something you do once, rather than for someone who sees it as an ongoing sport.  AMG includes a full set of allen-head screwdrivers for every one of the V12’s adjustments, though the instruction manual falls woefully short in terms of helping the uninitiated—there are no pictures.  If you haven’t set up your fair share of tonearms, this may not be the best place to begin your analog-setup journey.

The manual does warn you to use a light touch when making all adjustments.  The screws are all tiny: .65-, 1.5- and 2-mm allen-head screws that disappear into the casework, further contributing to the ultra-clean design.  But excess torque will destroy the subtle handiwork, so proceed with extreme care.

Another tip for those of you adding the V12 to your system:  Level the plinth before you attach the platter, as one of the three-adjustment screws is under the platter and cannot be accessed once you’ve fully assembled the table.  You should also be sure that the V12 is on a very solid surface, as the weight of this table will sink into any wooden rack shelves you might have.

Adding the optional HRS platform made specifically for the V12 boosts performance even further, with better low-level detail and transient slam, but the upgraded platform is not necessary—the V12 is enjoyable delivered from the factory as is.  But Leerer mentions that he feels the sound of any turntable can be improved by better isolation, such as that offered by the HRS platform, which offers a similar performance increase when I pair it with my fully suspended AVID Volvere SP turntable.  The HRS platform is a $2,500 upgrade that is well worth the investment.

Though the V12 requires a steady and patient hand to optimize it, the end result is more than worth the effort.  And if you subscribe to the philosophy of form following function, there may be no better example of record-spinning art than the V12.  Even the belt-drive mechanism is handily hidden beneath the platter—the mechanism slips on easily if you use the enclosed spiked wooden tool according to the manual.  (The turntable manual is much better than the tonearm manual, and it’s well illustrated.).  Röschlau makes it a point to mention that even this step, while appearing a style move, “Keeps the belt out of the environment and free of dust and UV rays.”

Recalibrate Your Senses

The V12 sounds as good as it looks, perhaps even better.  Immediately upon power up, the V12 feels solid and elegant—this is a serious record-playing machine.  The glowing red speed buttons turn to green with a mere touch.  And the V12 can accommodate 78RPM playback, for those with legacy collections.

We can argue about the merits and shortcomings of a 12-inch tonearm versus a shorter tonearm, but the main argument for a longer arm is minimized tracing distortion.  Here, the V12 succeeds brilliantly by utilizing an incredibly stiff yet lightweight tonearm wand that has an effective mass of only 12.9 grams.

A non-suspended design, the V12 table utilizes a massive CNC-machined plinth and an adjustable, high-mass aluminum “pod” pre-drilled for the tonearm mounting.  This removable pod uses a bayonet mount and is geared towards the analog enthusiast wishing to explore multiple tonearm and cartridge options. The finely gradated scale, where the base of the pod meets the plinth, makes it easy to perform the necessary adjustments for other tonearms with slightly different spindle-to-pivot distances.

Listening begins with a well-broken-in Lyra Kleos that has spent enough time on the AVID Volvere SP/SME V and the VPI Classic tables to be a familiar starting point for my review of the V12.  The AMG is considerably more expensive than the VPI and still almost a third more than the AVID/SME combination, and the presentation is markedly different.  Immediately, there is an increase in resolution from top to bottom, as well as a decrease in distortion.  A handful of albums from the “chronic-inner-groove-distortion” bin track through much easier than before.

Camper Van Beethoven’s Key Lime Pie just happens to be at the top of this list.  A record that has always felt fairly grainy and etched on top plays now tracks clean.  The inner cut on side one, “Light From a Cake,” used to have a more gravely feel to the vocals, usually causing me to prematurely end the side, but now it sounds smooth, with the drums greatly improved and the violin fluid, where this experience used to be torturous.

Investigating other problematic tracks reveals the same thing: an overall continuity and sonic integrity, with no sign of drawbacks.  Thanks to the Furutech’s incredibly handy disc flattener, there are no more warped records in my collection, so I can’t comment on the longer tonearm’s ability to track highly warped records.

Time Flies

Now that I’m comfortable with the sound of the V12, exploring different cartridges is in order.  Next stop is the Sumiko Palo Santos, which has been favorably reviewed here, and offers a similar tonal balance to the Koetsu Rosewood Signature Platinum.  Slightly rich tonally, this combination provides excellent extension and a somewhat warm rendition of the lower frequencies.

The AMG tonearm transforms the Palo Santos cartridge.  Sounding almost too warm and a little tubby with the SME 312 tonearm (also 12 inches), the Palo Santos snaps to life on the AMG, now with more definition in the lower registers.  Lynyrd Skynyrd’s classic Street Survivors, via the recent MoFi Silver Label release, proves enlightening, with the multiple layers of guitars now having more bite than before; yet, the overall presentation retains the smoothness that is the signature of the V12.

The more time I spend with the V12, the more the palette it paints feels like open reel tape.  Herbie Hancock’s masterpiece, Empyrean Isles, unfolds just as it did when I heard the master tape during the Music Matters remastering session, with the presence of each of the four virtuosos retaining distinctly separate spaces and with the musicians’ complex improvisations intact.  The V12 delivers percussion and cymbals that are rich with attack and decay, but that strike a perfect balance of timbre and tone.

Diva Approved

Of course, the female voice is the litmus test for so many audiophiles, so a thorough exploration again reveals the extremely low distortion this configuration is capable of.  Now, having moved to the Clearaudio Goldfinger cartridge, the bar is raised considerably.  Anyone doubting that this table can carry what is arguably one of the world’s finest (and, at $15,000, most expensive) cartridges is selling the AMG table short.

Marianne Faithfull’s take on the Rolling Stones’ classic “As Tears Go By,” from her 1987 record Strange Weather, is sublime, with the V12 extracting every bit of her addiction-scarred voice, and with Bill Frisell’s guitar hiding in the background, wandering in and out of the mix.  Faithfull’s voice is tough to capture, but the V12 gets every bit of grit out of the vinyl, highlighting the differences between the original pressing and the ORG 45RPM remaster.

Wilhelmenia Wiggins Fernandez’s rendition of Aria from ‘La Wally’ illustrates how well the AMG/Goldfinger combination paints the striking sustain of the solo voice in an operatic setting.  Much like being called on to reproduce the violin, the combination demands tonal purity and a wide dynamic range, or else the illusion is lost.  Fernandez’s voice feels as if it is floating in front of me, even on the most dramatic passages.  For those unfamiliar with this piece, it is featured on the soundtrack of the ’80s cult-classic film, Diva.

Let’s Review

After living with the AMG V12 since mid June, I’m as smitten with it as the day I first unboxed it—not always an easy feat in the wacky and rapidly evolving world of high-end audio.  It’s often too easy for the charm that captures you in a dealer or hi-fi show demo to fade all too quickly after the excitement of the purchase wears off.  A cursory look at the online buying-and-selling community Audiogon will reveal this to be the case with so much gear.

I’m happy to say that this has not happened with the V12—hence I’ve purchased the review sample to make it a permanent part of our reference system.   There is still more information to be culled from your LP collection, but it’s going to take a lot more money to get there, especially if you’ve paired your V12 with a flagship cartridge like the Clearaudio Goldfinger, Lyra Atlas or something comparable.

The AMG V12 is such an excellent value, in terms of performance for the price, meticulous build quality and timeless style, that we award it our Analog Product of the Year award.  -Jeff Dorgay

REL Classic 98 Subwoofer

REL has achieved a well-deserved reputation for making some of the (if not the) world’s highest performing subwoofers. Whether you have a single, pair or a six-pack, you can count on REL to deliver solid, defined bass response with prodigious output, mating invisibly with the main speakers. Considering how much speakers have evolved over the years, few can even make this claim, yet deliver the performance to back it up. Bass response is like any other aspect of audio – we all have our preferences.

Whether you want to use a subwoofer with a vintage pair of speakers, or just prefer your sub to deliver a bit more tonal saturation in the upper mid bass, the fastest, most transparent subwoofer may not make for the combination you desire. Putting a set of Michelin Cup 2’s on your vintage sports car will yield the same results – that much grip is not always the best thing. Enter the Classic 98. With its down firing 10-inch woofer in the tradition of earlier REL subs and walnut finish, it is the perfect sonic as well as aesthetic companion for your favorite classic speakers, British mini monitors, or even a set of high-sensitivity single (or coaxial) driver speakers. I did some serious listening with a number of different speakers to confirm this. And a big thanks to Kevin Deal of Upscale Audio for sending a PrimaLuna EVO 100 integrated amp and a pair of Tannoys to round out the picture.

REL’s John Hunter shares my love of slightly vintage/current classic audio, and we both have way too much of this gear in our respective collections, which have only grown over the last few years of semi-confinement. However, when it comes to older speakers like his KEF Ref 101s or original Wilson Watts, my Acoustats and original JBL-L100s, the fast, tight bass of a modern subwoofer doesn’t quite integrate as it should. Enter the Classic 98.

Tasteful modifications and improvements

While high performance rubber may upset the balance of your semi vintage car or motorcycle, there is always a level of tasteful, subtle modifications that can yield a vehicle outperforming the original enough to be more engaging, yet does not defy the character of the initial design brief, or upset the balance so much that you spend a ton of money and lose your way. Ask me how I know this.

Hunter tells me that they laid down the initial priorities to build a “new old stock REL of his dreams, that is just vintage enough in sound and styling – a little softer and more romantic (but still with the room filling bass you expect from REL) than current models.” Though he still has a REL Strata III on hand for reference, it didn’t quite keep pace with his memories. When placed into a semi vintage system, the Strata III was a bit too warm.

REL has adapted the look of their first subwoofers, with a luxurious satin walnut finish to a contemporary size. If you recall, the original Stratas were big boxes. The Classic 98 uses a hot pressed paper coned, 10-inch driver with a cotton center cap. It looks very vintage when you flip the Classic 98 over, but Hunter is quick to mention, “We know a lot more about paper than we did 25 years ago. The result is purer and more refined, retaining some of the rounder, gentler qualities of that era, yet steers clear of being dark and muddy.”

As you unpack the Classic 98, its build quality is instantly apparent. The cabinets are finished in a lovely matte finish and compliment the Tannoy’s perfectly. Good as all the combinations were, these tiny Tannoys and the Classic 98 are as good as it gets together. 40 watts per channel of tube power is all you need to enjoy this system.

When you find the optimum position for your Classic 98 and have the initial settings where you want them, have a friend dial the level control all the way down, play your favorite bass heavy track, and slowly bring the level up. Go back and forth, over and under the sweet spot until you have it where the subwoofer is no longer feeling like a separate speaker element. Experiment with the crossover frequency set slightly lower than you might think, with the gain slightly higher, and repeat the process to perfection. Then sit back and rock on.

When it’s right, you get more low frequency energy, but the sub calls no attention to itself. Try the opening of Rickie Lee Jones’ “Easy Money,” (from her self-titled album) and the opening of Bachman Turner Overdrive’s “Not Fragile” (from Not Fragile).

The players

Five speakers were auditioned with the Classic 98, all with fantastic results. The Heretic A612, Tannoy Prestige Autograph Minis and Harbeth Compact 7 were excellent modern speakers with a more vintage feel. A pair of original, mint JBL L-100s, Acoustat 2+2s were the vintage contingent. All five of these speakers have a slightly soft, warm bass response. Think more like the sound of a Dynaco Stereo 70 instead of an Audio Research REF 80S. Inviting and pleasant, even if not the last word in resolution.

Power was provided by the PrimaLuna EVO 100 integrated amplifier (40 wpc/EL-34 tubes) for most of the listening, with the First Watt SIT-3 (20 wpc/solid-state) an alternate choice. The dCS Vivaldi ONE provided music to the test setup, with the Pass Labs XS PRE combined with the First Watt as it is a power amplifier only.  All cable for this system was the latest Studio ONE from Audience.

To stay in the period groove, I didn’t listen to any of the usual techno or hip hop tracks I usually listen to when evaluating modern subwoofers. It was 60s, 70s and early 80s rock all the way. The completely groovy bass line in the Cowsills “The Rain, The Park, And Other Things” takes on a new dimension, filling in with the extra weight that the vintage speakers always needed. Next up, Dark Side of The Moon. Smiley face EQ-d MoFi vinyl no less. Get over it, it is fantastic.

All of the speakers in the test lineup required different settings, easily adjusted. Like all RELs, the Classic 98 has rear mounted controls for level, crossover, and LFE (should you have them in a surround setup but ignored here) connected by a speakon connector to your amplifiers speaker outputs. Of course, you can use line-level preamplifier outputs, but the results will not be quite as good, especially in terms of subwoofer to main speaker integration.

With a pair of vintage, or vintage-ish speakers as mains, adding the Classic 98 gives them the extra grunt they all need, without calling any attention to itself. I took Hunters’ advice, poured a bit of whisky, leaned back in the Eames Lounge, and played records all night. Even though my main speakers were right there, dormant with the REL six pack they are connected to, I never really had the urge to fire up the big system. This combination made for a great evening, and the total system cost was well below $10k. Even with more current music. With the Classic 98, you can create a magical, musically engaging system that’s so much fun, you might even forgo something more resolving. This is audio comfort food at its absolute best.

You didn’t know you need it but you do

The REL Classic 98 might just be the ultimate audiophile guilty pleasure. At $1,398 it embodies the same high level of quality that every other REL I’ve owned or used is famous for. Much as I’d like to tell you I bought the review sample, I couldn’t – they don’t have inventory yet! However, by the time this review is live you and I should be able to put our hands on one of these. Run don’t walk. I often suggest getting a pair of RELs (or a six pack), and the same applies here, but you can certainly have fun with a single Classic 98 to start. The downward facing driver makes for a bit more omnidirectional delivery, less critical of placement, and fits in with the tasteful presentation.

Aside from this being a product that completely hits the mark, I really enjoy that this was a labor of love project for John Hunter. It’s perfectly executed, yet affordable and approachable. This is something the high end needs more of. Hunter closes our conversation stating, “The Classic 98 is a chance to revisit REL’s rich heritage. We strove to remain true to Richard Lord’s basic principles and styling. We restrained ourselves from simply building a modern REL in a walnut cabinet.”

To his point, they have succeeded – to perfection.

The REL Classic 98 Subwoofer

It may look retro, but rest assured the new Classic 98 from REL delivers the goods. This is a unique sonic tool, geared more towards listeners that enjoy vintage/classic speakers, with a slightly warmer low-frequency response, or perhaps a British monitor, with some of the same. Ever hear Harbeth owners complain that you can’t mate a sub with them? Now you can.

But let’s stay in the vintage groove for now. We’ll release the full review later today, but suffice to say that if you’ve got a pair of speakers from the 60s to the early 90s that you are really fond of, but would enjoy a bit more extended bass response while keeping in character, this is the droid you want. With a downward-firing, paper coned 10-inch driver and 300 watt amplifier, it’s still a REL, but subtly tuned for the application.

REL’s John Hunter has created a masterpiece that is voiced to be ever so slightly more tonal saturated and robust in the mid-bass, and a bit softer on the bottom of the LF register, but not soggy and slow like the subwoofers of that era were. It’s a perfect fit for a lot of classic speakers, and one we recommend highly.

YG Acoustics Cairn Speakers

Listening to the expansive sound field created by the tiny YG Cairns, with a pair of 8-foot tall electrostatic speakers in the background is really impressive, but not surprising.

The opening of Tears For Fears “Woman in Chains” is big and broad – paying homage to some of the best studio craft the 80s had to offer, with stuff panning around everywhere. Switching to Lou Reed’s “Vanishing Act” is equally exciting, with his voice and solo piano sounding larger than life. It’s almost hard to belive that all this music is coming from a pair of diminutive (14.6 x 7.6 x 10.3″) monitors on 24” tall stands.

I had the good fortune to visit the YG factory in Colorado at the beginning of April, to experience the entire Peaks line of speakers. In their purpose-built room, everything on display not only sounded incredible, but clearly illustrated where the increases in performance occur between the entry level Cairn and the top of the range Summit at $25,000/pair.

Duncan Taylor and Steve Huntley were even kind enough to put up with my quirky musical tastes, but that made it very easy to get a quick read on what their speakers can accomplish. If you only remember YG for their exquisitely machined aluminum enclosures, the new Peaks have wooden cabinets, that retain the thick, inert aluminum front face. Though the precision machined waveguide for the tweeter in the Peaks series is quite different than the reference series, the look makes them instantly recognizable as a YG.

Taking care of business

Listening to the Cairns in my 24 x 36-foot room, which is at least similar in volume, provides equally engaging results. While Taylor is a master set up person, even just plopping them in my room for an initial listen is still excellent. The wave guide giving the patented YG ForgeCore tweeter a wide dispersion pattern, not only helps to make these speakers easy to set up, they provide a large enough sweet spot that everyone can enjoy the music. As with any great hifi speaker, the best seat will always be right in the middle, but the Cairns deliver an expansive enough experience that they sound great off axis, and even sitting on the floor as a casual observer/listener.

In the big room, final placement ends up being about ten feet apart and about four feet out from the rear wall, with about 7 feet on each side. This makes for an incredibly open sound, and even in this size room, the amount of LF energy these small (6”) woofers can generate is truly impressive.

Speaking of stands, the machined 24” tall aluminum stands that will put the Cairn tweeters at the perfect height will set you back another $1,500 – but they are worth every cent. Machined at the same level of the rest of the YG lineup, they include small dimples on the speaker platforms, so you never need worry about a perfect speaker/stand interface. And you never need to worry about bumping them out of alignment. This is the only quandary with the Cairn, do you spend $10k for speaker and stand, or go all out and invest $14,200 in a pair of Talus floorstanders, taking up about the same amount of space? Great as the Cairns are, someone with little ones might just want to get the floorstanders.  

(Lack of) sonic signature

The original YG speakers were billed as the “world’s greatest speakers,” and to be fair, they were indeed very good, but a bit on the overly analytical/harsh/fatiguing side. We enjoyed their stay, but they were only lovely on your best recordings. Everything else felt over-caffinated. (or something a little less legal, if you know what I mean) So much time and effort have been put into all of the current YG speakers, forget everything you remember about the past.

The result is a speaker that is both highly resolving, yet not fatiguing. Tonally, they are extremely natural, so you can leave the final system voicing to your taste. While the Cairns sound different with tube amplifiers than they do with solid-state, both are pleasing, and it’s up to you to decide the ultimate flavor of your audible experience. You don’t notice immediately just how uncolored these speakers are until you go back to something else. And then it hits you.

YG does not mention the Cairns crossover frequency, but the sheer seamlessness between the woofer and tweeter is pure success. There’s no beaming, cutoff, or the sense that you are listening to a separate woofer and tweeter. Tracking through numerous female and male vocalists is enjoyable, without anomalies of any kind. Stringed instruments sound correct – as well as violins and pianos, my favorite torture tests.

Final voice is up to you

Trying the Cairns with everything from a 8-Watt/channel SET amplifier (The ampsandsound Black Pearl, with WE 300B tubes) up to the mighty Pass XA200.8 monoblocks is a fruitful endeavor. Thanks to an unobtrusive crossover network, these 86db/1-Watt speakers sound absolutely engaging, even with the 8 Watts per channel the Black Pearl has to offer. At least to a certain volume level.

While 8 Watts per channel is somewhat shy, 30-50 will serve you well in all but the largest rooms. The PrimaLuna EVO 400 power amplifier in stereo mode with EL34s delivers a warm, yet resolving groove. Substituting KT150s offers more mid to top end snap. The versatility that the YGs offer is so much sheer fun, you might get lost in the experimentation! And isn’t hifi supposed to be fun? Even with warmer tube amplifiers, the sheer resolution that the Cairns provide allow you to re-examine your music collection. The only danger with the big Pass amplifiers was watching the volume control when listening to music of a more electronic or hip-hop groove. A six-inch woofer can only move in and out so far. And the Cairn exhibits so much raw ability, it’s tempting to keep twisting the volume control.(and damage the woofers)

YG has promised to send us their Descent subwoofer from the Peaks lineup for a second listen with the Cairn, but for now, bringing a REL Carbon Special into the mix, confirms how much a topnotch subwoofer can flesh out the sound of these incredible speakers. Thanks to the dynamic, punchy nature of the Cairns, the last bit of LF reinforcement from a sub expands their already large soundfield.

Editors note: since we originally published this review, YG has sent us their matching Descent subwoofer and it’s the perfect match. We’ll have a full review very soon.

The details

From a performance standpoint, the YG Cairn speakers are a true bargain. Closer examination reveals an attention to detail usually reserved for Formula 1 cars. The sophistication of their machine shop where the aluminum cabinet parts, the woofer cones and other parts are an exercise in top level design and implementation.

The YG team doesn’t miss a single thing. Even the binding posts are shipped with threaded protectors to keep the posts from being snapped off in shipping. Ask me how many times this has happened over the 20 years of TONE reviews? What a considerate thing to do.

As an admitted technology geek, I pretty much freaked out at how attentive YG is to every single aspect of their design and manufacturing. Company principal Dr. Matthew Webster is a Stephen Hawking smart kind of guy and told me about how much time and money they spent on Amazon’s supercomputing network to not only optimize speaker design, but modeling how their speakers would work in every possible environment with different components. This level of engineering just isn’t done in audio. It’s a wonderful thing when the technology serves the music like this.

Raw tech just for tech’s sake isn’t worth diddly if it doesn’t work. The YG speakers succeed on every level and are one of the easiest to set up and integrate into a wide range of cables and components I’ve yet experienced. That’s worth a lot, especially to those entering the realm of high-end audio, as their capability for some of the fussiness that seasoned audiophiles take for granted hasn’t developed yet.

The YG Cairns offer an exceptional amount of performance for the most demanding music enthusiast, and so we are more than happy to award them an Exceptional Value Award for 2023. These speakers are the most thought-out product I’ve had the chance of using, ever.

The Peak Consult Sinfonia Speakers

Listening to Kraftwerk’s “Boing Boom Tschak” through the Peak Consult Sinfonias has so much information in all three dimensions, it’s almost psychedelic. Tracking all the way through the Techno Pop album is almost too much fun. The sonic field created by these speakers is so enormous, you might think you were listening to a pair of big Sound Lab ESLs or MartinLogan CLX’s. However, the punchy bass convinces you these are no panels. Peak Consult has always had a way with sound.

The picture you see above is interesting because about 15 years ago we reviewed the Peak Consult Princess speakers and loved the engaging sound of these compact floor standing speakers. At the time, they had an MSRP of about $15,000/pair and were worth every penny. If you’ve ever seen a pair of Peak Consult speakers, you know that the build quality is incredible and even the small Princesses weighed over 100 pounds each. To say that these artisan-built cabinets are inert is an understatement. The Sinfonias you see here are $55,000/pair, and weigh 165lb. (75kg) each.

In my forgetful way, I neglected to send the accessory package back, containing a cleaning cloth, some cleaner for the leather surfaces, and a bottle of oil for the wood surfaces. When I called the late Chris Sommovigo, who at that time was the Peak importer, he said, “Just keep it, we’ll be sending you another pair for review shortly.” As fate would have it, that did not happen, and the Sinfonias were a welcome site, their large crates arriving practically the day I decided to tear all the walls down in my listening room. So, they stayed hidden in the garage, with my Mini pushed back to within a few millimeters of the crates as a bit of extra “security.”  

Fortunately, all went smoothly, the walls came down, and the Sinfonias are now strutting their stuff in a 24 x 36-foot room. Initial setup attempts where past speakers sounded good yielded a slight upper bass bump, so after several different placements, they worked magnificently about three more feet into the room than before (which would not have been possible in the old room) and also on the long wall, with nearly 12 feet on each side of the speakers. While I realize not everyone will have this option, it is glorious.

Taking care of business

Because the Sinfonias have substantial low bass output, these are not speakers that can be casually placed in the room, and because they also deliver high resolution, it is to your advantage to take the time to carefully place them. First setting up for proper bass optimization and coupling to the room is key. Then, a bit of experimentation with rake and toe-in to get just the right amount of high-end sparkle takes them the rest of the way. These 172-pound (each) speakers are remarkably easy to remove from their shipping crates and thanks to some Teflon pucks on hand, easy to move into place singlehandedly.

Peak’s soft dome tweeter is smooth, yet resolving (I admit a bias for the sound of soft dome tweeters, so take that for what it’s worth) and the level of coherence provided is definitely reminiscent of a full range design. This is a true testament to the meticulous crossover network inside, which crosses to the midrange driver at 3,100 Hz and then again to the woofer at 450 Hz. This rear ported design claims to be 3dB down at 25 Hz on the bottom and 30 kHz up on top. While we don’t do specific measurements, playing a series of test tones reveals only slightly diminished output going from 30 to 25 Hz, but then dropping substantially from 25 to 20 Hz. But that’s what REL six packs are for…

Even the most dedicated bassheads will be more than happy with the low frequency performance of the Sinfonia. The biggest difference between these and my last reference speakers, the Sonus faber Stradivari’s’ is the quality of the LF output and an equally natural, yet more resolving midband. Listening to a wide range of tracks with serious energy in the lowest part of the frequency spectrum is very rewarding.

The opening track of Joni Mitchell’s Don Juan’s Restless Daughter features some incredibly low bass notes played by Jaco Pastorius, that are tough to capture on vinyl, but absolutely growl when played back from a 24/192 digital file. It starts at 1:45 in, and these riffs punctuate the track. While the single woofers in each Sinfonia cabinet can not produce the sheer output of my six pack of REL no.25 subwoofers, what’s most important is that the definition and quality provided is incredibly close. Precious few speakers at any price can deliver this.

It’s about the cabinet

So much has been carefully optimized in terms of driver and crossover design, yet the cabinet is a huge part of the equation. Chatting with Wilfried Ehrenholz, the principal at Peak Consult, he makes it a point to discuss the complexity of the Sinfonia’s enclosure, which features a 45mm thick (almost 2-inches) front baffle and a cabinet made up of multiple materials, bound together with a special flexible adhesive. These layers work together to absorb the unwanted resonant energy instead of clouding the sonic presentation. “Like in two different restaurants, using the same ingredients, one meal is fantastic, and one is average. The design team on the Sinfonia has a combined experience of nearly 80 years in the speaker business – that makes the difference.”

He goes on further about the cabinets to emphasize that they are made entirely in-house. “You can not go to a cabinet supplier to get all the crazy custom work we have done to these cabinets. It must be done in-house.”

For those of you not familiar, Ehrenholz is the former CEO of Dynaudio, recently out of retirement to work with Peak Consult. Karl-Heinz Fink (of Fink Team) has been enlisted to work on the crossover design and perform all the measurements. Ehrenholz goes on to comment, “we are very efficient in our design process. Karl-Heinz has very sophisticated measuring equipment and knows exactly what he’s doing, so before we start, he’s measuring drivers. By the time we start listening, we’re already about 70% of the way there.”

In addition to the cabinet, the Sinfonias (like all PC speakers are coupled to the floor by “Serenity bars.” These stainless steel footers at the bottom of the enclosure have screw in steel pods with high quality ceramic balls, supporting the entire weight of the speaker, with less than 1 square millimeter actually coming between the ground and the speaker. This not only decouples the speaker, but eliminates the need for potentially damaging spikes. Beautiful, precise, and unique.

This is only part of the story. Quality mavens will be excited over every inch of the Sinfonias, from their gorgeous wood cabinets to the lovely leather front and rear faces. The quality of execution is every bit as good if not better as what comes from Sonus faber in Italy. These are speakers you will be excited to have in your environment.

A quiet calm

If you bought a Bentley Continental as your first luxury car, you probably wouldn’t appreciate just how special it is, and so it goes with speakers. I gently suggest that the more you’ve heard, the more you will appreciate these speakers. Their lack of tonal coloration makes every kind of music welcome, and their high level of resolution will bring numerous “a-ha” moments to the time spent in front of them.

Like the Bentley they do everything at such a high level of quality, you almost forget how much work went in behind the scenes to make it all seem so easy. Swapping components in and out instantly reveals the changes made, so while being incredibly musical the Sinfonias are incredibly useful as a reference speaker as well. Whether you are a music lover, gear geek, or any combination thereof, you’ll be equally enthralled with the Sinfonias.

Specs aren’t the whole picture

One more aspect of the Sinfonia’s design that Ehrenholz is particularly proud of is the crossover design. Thanks to their Peak linear impedance control (PLIC), they claim the impedance only varies +/- 1 ohm with a nominal impedance of 5 ohms. The Sinfonias also have a claimed sensitivity of 89dB/1 Watt.

In addition to the seamless blend of the drivers, the PLIC is a low-loss crossover network. Not all speakers with the same sensitivity measurements are equally easy to drive. Thanks to this design, even driving the Peak’s with the 15-watt per channel ampsandsound tube monoblocks is a success. Some crossover designs that are more complex tend to lose the first few watts in the network – no big deal if you have 200-Watt monoblocks. To make a long story short, the Peaks are incredibly tube friendly.

All things considered, anything above about 40 Watts per channel will drive the Sinfonias, but how loud you need to go will determine how much more power you’ll need. Much as I love my reference Pass XA200.8/Pass XS Pre combo, the absolute magical combination has turned out to be the new PS Audio BHK 600 Monos, driven by the incredible ART88 preamplifier from conrad-johnson.

The PS amps deliver slightly better bass control at higher levels, and the CJ preamplifier images like nothing I’ve ever experienced – again proving how resolving the Peak speakers are. Every change, no matter how minute is easily discerned. This will allow you to fine tune the result exactly to your liking with ease. That being said, there wasn’t a combination I didn’t like.

More listening

Because the Sinfonias are so engaging, I listened to even more music than normal, both in dedicated listening, and just for background music while doing other things. No matter what music was playing, it was all enjoyable. Nothing caught me off guard, whether listening to solo piano or guitar, to larger scale orchestral works, or the heaviest rock music. Having heard the last version of their top-of-the-line Dragon at contributor Richard Mak’s house, the only thing the Sinfonia does not deliver, is that last half octave of low bass, and the ability to play louder. But I don’t listen as loud as Mr. Mak does, so for me the Sinfonias are just fine. All of the Peak Consult speakers share a similar voice, which again speaks to the excellence of the design team.

In closing I ask Ehrenholz when he and his team know when to stop the design process and go forward with the final build. “When I have no further ideas on how to improve, then we stop.” The proof is in the listening. While I am no speaker engineer, I have certainly listened to a lot of them over the past 40 years, and I must agree, there is nothing I would ask the Peak Consult team to improve in the Sinfonia. These are by far one of the most musically satisfying speakers I’ve had the pleasure to spend time with. I feel they have certainly met their goals. In my room with my system, they are absolutely heavenly.

Vera-Link: The most fun you can have for $199!

Some of you may remember Mark Schifter for all the fun products he came up with during his tenure at Audio Alchemy. They made some incredible products that had cutting edge performance, in tiny enclosures, with tiny price tags to match.

Many an audiophile started their journey with one or more Audio Alchemy components. Well, you can’t take the fun out of the boy, and his latest product, the Vera-Link is a 50 watt-per-channel class D amplifier and streamer, built into a box about the size of a deck of playing cards. While this may not sound super “audiophile-y,” because you can only get so much for 200 bucks, but the Vera-Link does sound pretty damn good for what it is. Certainly, better than a $300-$500 vintage 70s receiver that needs to have all the caps refreshed, that still needs a streamer. And, you can control up to five zones from your phone, so put those surplus speakers to work!

Substitute the word audiophile for fun

Now you’ve got it. I’ll bet you’ve got a great pair of older vintage speakers lying about that you’d love to press into service, or perhaps make more mobile – i.e. take em’ out on the porch/patio when you’re grilling, maybe even throw in the back of your truck for a trip to your favorite camping spot. But how to power them? If you’ve got any kind of inverter, you can run the Vera-Links that way. To try a mobile battery solution I used the two supplied wall warts with a 1400W Yeti battery supply with excellent results. All that’s left is to pair the amps with your Bluetooth streaming device. Vera-Fi even provides the Velcro to attach these babies to the back of your speakers. After the better part of an afternoon, the Yeti went from 100% capacity to 96%, so the current drain from these is minimal.


While I tried the Vera-Link with a couple of speakers that are way more expensive than what you’d choose to pair them with, it does reveal the engineering prowess at work. Even connected to the Eggleston Nicos that were on the cover of issue 102, listening to the strings at work with Al DiMeola, Jean-Luc Ponty, and Stanley Clarke’s Live at Montreux 1994, is highly enjoyable. No, it’s not a pair of Pass Class-A monoblocks enjoyable, but it’s way better than my neighbor’s crappy $800 Alexa speaker.

To make things more equitable for the little amplifiers, the next choice is a pair of vintage A/D/S L400 speakers. Thanks to the magic of Velcro, an older pair of Cerwin-Vega speakers are brought into play as well as a really old pair of Dynaco speakers. (Remember those?) Think thrift store fun here. Upping the budget a bit, the XSA Vanguards were also brought out for a test drive with excellent results making for a great portable system as well. However, I’m just so enamored with the simplicity and low-budget ethos of the Vera-Link, I like the lower priced speakers. An iPhone 14 was used as a source, and files streamed to the Vera-Link with Roon (16/44) and Spotify (320kb/sec).

The Vera-Link certainly has enough resolution to hear the difference between CD quality and 320kb files, but it’s not enough to discourage you from using your favorite $100-$200 pair of speakers and not being able to enjoy music. Perhaps the most amazing aspect of these tiny, non-distinct amplifiers is how far Class-D amplification has come. The A/D/S are my favorite budget/vintage speaker, with great midrange and smooth highs. They make a wonderful match with the Vera-Fi’s. And while we don’t do measurements, they certainly can play loud with these amplifiers, easily as loud as my vintage Marantz 2275.

When listening to heavier rock selections, as well as some of my favorite fusion tracks (lots of Stanley Clarke and Herbie Hancock) the Vera-Link’s ability to play complex music really shines through. Go back to that Montreux album and listen to Stanley Clarke’s bass solo. Yow. These amplifiers not only deliver robust bass extension, but good bass control.

Short and sweet

Other than the fact that these amplifiers are very musical, play loud without distortion, and have much less grunge than you would ever expect from a $200 pair of monoblocks (albeit Barbie Dream House sized monoblocks) there’s not much more to tell. They sound great, are unobtrusive, and offer no-fuss, no muss setup. If the audiophile bug still won’t let you go, plug the Vera-Fi’s into a linear power supply for even better sound – but you lose some of the portability.

Seriously, I’m buying a pair for my tool box. Why wouldn’t I? You never know when that vintage receiver is going to take a dump, or a friend in need has the same problem. They are going to go right next to my battery jump box. These would make great stocking stuffers, or even a great way to get your favorite budding audiophile one step further down the path. As I mentioned earlier, these are also a great way to have portable high-end sound anywhere. This is such a cool product, I think everyone should have a pair of these.

Keeping the discs spinning – Naim’s CD5si

What’s more intriguing in 2023? That vinyl’s upsurge refuses to subside, or that some music lovers still love their CD collections? Crazy as it may seem, CDs are still being pressed, and used CDs languishing on music store shelves are one of the best bargains going.

Naim has always made fantastic CD players, and the CD5si is the sole survivor. And for about $1,600 it’s a killer value. The build quality is much like their old flagship, the CD555. Thanks to Naim’s own semi-circular, manual drawer, this is a robust drive mechanism indeed. All the bits you can’t see (clock, power supplies and the latest Burr Brown PCM 1793) contribute to a highly musical player at a budget price.

We’ll have a full review very soon, but if you’re looking for that last, reasonably priced, yet high performance CD player, we can’t suggest the CD5si highly enough. Note, this player does not have DAC or streaming inputs. The CD5si does one thing – play CDs with RCA (and Naim) analog outputs, and it does it incredibly well.

The PrimaLuna EVO100 Phono

Listening to PrimaLuna’s new tube phonostage begins with an audiophile cut for a change. If you haven’t had a chance to hear Earth & Wood on Yarlung Records, this is an incredible piece of music exquisitely captured. The tone and dynamics are out of this world good. Seeing the EVO 100 Phono has a 50-ohm setting for MC loading, Rega’s Apheta 2 mounted to a Rega P9 is the toughest cartridge to drive on hand. The Apheta cartridges often get a bad rap at being thin and strident sounding, but nearly all the time they are loaded at too high of an impedance setting. 25-50 ohms is the key to unlocking the speed and transparency that this cartridge offers, and the EVO is a perfect match.

Next up, the SME 20 with a Lyra Helikon reworked by Ana Mighty Sound delivers a completely different voice. Not quite as contrasty from top to bottom, the Lyra has considerably more inner detail and front to back depth. Tracking through a handful of Blue Note remasters delivers a luxurious, texture filled presentation, that brings these classics to life.

Going off on a different tangent, the Technics 1200GR with Luxman LMC-5 is the last choice, again, we’re talking about different and subtlety, rather than hit you over the head differences, but you should know that the EVO 100 possesses more than enough resolution to let all of these different cartridges shine.

A long time in the making

PrimaLuna fans have been asking Herman van den Dungen at PrimaLuna when they would make a killer phono stage offering a level of performance and value to match their award winning amplification products for some time now. They’ve produced a CD player and recently a DAC – both upholding the PrimaLuna traditions of value, performance, and execution. (Staffer Sean Zloch owns the DAC and loves it, btw.) You have to hand it to Mr. van den Dungen for keeping a poker face, he’s never even hinted that they were actually doing this project.

Well, it’s here and it’s fantastic. Though it’s commonplace today to spout superlatives at every turn in the audio reviewing world, the EVO 100 Phono gets highest praise, as I own a handful of great $10k-ish phonostages from ARC, Backert Labs, BAT, Pass Labs, and VAC. The 20k-ish Nagra Classic Phono is also here for listening, so when I say that the EVO is one of the best deals going in a $3,700 phono and delivers performance you’d expect to pay more for, it’s not empty praise. It’s been compared to several great phono stages, with a wide variety of cartridges.

PrimaLuna has been around for 20 years now, and their components stand the test of time. Check your favorite internet forum, EBay, or Audiogon. There’s rarely many used PrimaLuna components for sale. People tend to keep em. For those of you that haven’t heard me say this often, I still have my ProLogue One integrated that I reviewed for The Absolute Sound 20 years ago. Just over 2,500 components have come through the door as TONE approaches its 19th birthday, and this one’s still delivering the goods. So, this is a product you can buy with total confidence.

Break it down again

The EVO 100 Phono uses a half-sized chassis, like the original PrimaLuna integrated amplifiers, the current EVO DAC and the EVO 100 series products. The physical design and styling match all PrimaLuna products, with the familiar dark blue metallic chassis, black or silver matte front panel, and the Coney Island Hot Dog warmer tube cage. It also comes triple boxed to make sure it is not damaged in transit, and a pair of gloves so you don’t smudge it when installing. If this is your first go around with PrimaLuna, you’ll be impressed with how well their products are packaged.

Though the EVO 100 Phono offers MM and MC capability, there is only one phono input on the rear panel. This is the only real complaint I have with it, and it’s unfortunate that they couldn’t have at least gone the route of having a separate MM and MC input, allowing you to use two turntables, or even using an external step-up transformer with the MM input. A single pair of RCA outputs are also supplied for output to your preamplifier or integrated of choice. With a pair of 6922 tubes for the MC stage, the main gain and MM stage each use a pair of 12AX7 tubes. And all the gain tubes have those vintage coolio metal cans to keep noise down.

Space the final frontier

Even though people are still arguing about analog versus digital, the spaciousness that analog brings to the listening experience is always exciting. Side one of Earth & Wood features Lou Harrison’s 1940s “Canticle No. 3.” Performed by the Smoke and Mirrors percussion ensemble, this track features a steel guitar and a number of vintage percussion instruments. The closest comparison would be to some of the Mickey Hart Drumming at the Edge work. The spaciousness of this recording through the recently installed Peak Consult Sinfonia speakers is massive.

Moving back to more familiar territory, Paul Weller’s first solo album proves equally engaging. Though this record feels digitally mastered, that feeling of a nearly endless soundstage is incredibly cool, revealing fine details not as easily discernable in the Japanese CD version. Isn’t that what vinyl is all about? Uh huh, oh yeah.

The vinyl version of Kruder & Dorfmeister’s The K&D Sessions is perfectly suited to this turtable/cartridge setup, and the tonal saturation that the PrimaLuna adds to the Rega makes for a Technicolor/Superscope presentation. The bass hits hard, and the tinkly bits float around the room. This all-tube design is a master of rendering three dimensional space, precisely the thing I gravitate towards tubes for.

MM and MC

While Chris did not achieve incredible synergy with the EVO 100 and the MM cartridges he had on hand, the Technics 1200G and Concorde Silver (basically a higher performance Ortofon OM40 in a Concorde body) used here was perfection, as well as our other MM reference, the Clearaudio Virtuoso Wood. Both delivered the dynamics you associate with taking the MM path. My least favorite matchup with the EVO 100 on the MM side, was the Linn LP-12 Basik, sporting their Adikt II cartridge. Sometimes it’s just how the planets line up, but this combination is already somewhat on the romantic side, so this might just be a bit too much of a good thing. And remember, I’m the guy on the staff that leans to the warmer side of things.

An interesting aspect of the EVO 100 Phono is the all-tube design – no step up transformers, Op amps, or solid-state gain stage anywhere. A pair of hand-picked 6922s are hidden around back, in a sub enclosure (behind a little door) with the circuit board suspended from the main chassis. You simply remove a small pair of posts to remove the door for tube access. This only delivers 60dB of maximum MC gain, but also adds a level of circuit purity and tonal saturation that others do not. The medium and low gain settings are 56dB and 52dB, handy if you have a high(er) output MC that ranges from .9mV to 2.5mV.

It’s slightly on the low side for something in the .25 – .30mV range, like a Denon 103 if you have a preamplifier/linestage with low to moderate gain. However, when feeding the Pass XS Pre and the conrad-johnson ART88 (in for review) we had no problems with lower output cartridges. And it’s a perfect match for an all PrimaLuna system. If you have a MC cartridge in the .4mV – .6mV range, you will be fine regardless. The EVO offers loading at 50, 100, 200, 500, and 1000 ohms for MC and two capacitance settings of 47pF, and 100pF for MM.

Many different system configurations were tried, however most listening was done with the Pass gear and Peak Consult speakers. While the EVO 100 lacks the ultimate level of resolution of the $10-$20k phonostages on hand here, (as it should) to coin an old audiophile cliché, they are only sins of omission. Yet dynamically, the EVO leaves precious little on the table compared to some of the industry’s finest thanks to the enormous power supply with tube rectification handled by a pair of 5AR4s and regulation from a pair of EL34s. It’s like getting out of a Carrera GTS and getting into a standard model 911. After about half an hour, you don’t really miss that extra 50 horsepower all that much.

I have to confess to not being much of a tube roller, but considering the luck I have had with PrimaLuna pre and power amplifiers, I’m guessing those of you that want to invest in some premium NOS tubes for this phonostage can probably wring even more performance from it. This is not to say it is necessary to enjoy the EVO 100, but the most fanatic among you can probably take it a click or two further, should you choose to experiment.

There was a time that almost four grand was crazy money for a phonostage. Today not so much, but for many analog enthusiasts this is still a major commitment of resources. To that effect, the EVO Phono is more than worthy of an Exceptional Value Award for 2023. I know I could live with one of these forever – and with shopping season around the corner, i still may purchase one. Highly recommended.

To get a better handle on how it stacks up to something much more in the same price neighborhood, I sent it over to Chris’ house for a while as he has been listening to the Modwright 9.0 SE (now with X mods) for some time. Here’s his take on the two.

Additional listening; Chris Harr

For several months, I’ve been thoroughly enjoying ModWright’s PH 9.0 phono stage ($3,500). So much so, I recently returned the unit to ModWright for the “X” upgrades (+$1.250). While the “X” mods are entirely positive, they don’t transform the PH 9.0 into an entirely different phono stage. For that reason, it seemed obvious to compare it to the $3,695 PrimaLuna Evo 100 Tube Phonostage.

For initial listening, the PrimaLuna Evo 100 Phonostage is paired with an Avid Volvere SP with a Kuzma 4 Point 9 tonearm. The phono cartridge selected is an Ortofon Cadenza Bronze modified by Andy Kim at the Needle Clinic with a boron cantilever and micro ridge stylus.  Listening to the Evo 100 phono stage, I’m quickly struck by a smooth, liquid and well-layered midrange while listening to Clementine on Halsey’s (Ashley Nicollet Fragipane) Manic album. Make no mistake, Halsey is a pop singer/songwriter of a special quality. Her voice carries a textured emotional depth and the PrimaLuna allows that nuance to be clearly heard. Contrasting overdubbed vocals emerge from a space behind the main vocal rather than blending with the primary vocal. The effect is haunting, in a good way, as though we’re hearing a bit of raw emotional desperation.

Later, listening to “Little Death” from The Beths’ debut album Future Me Hates Me, I’m greeted with the expected crystalline triangle-type sound at the beginning of the track followed by a rapid, light cymbal tap before the song transitions into wall of electric guitars over the top of galloping drums. The Evo 100 keeps the dense instrumentation well-separated and clearly placed in the soundstage.

Next, a ProJect X8 with a Nagaoka MP-200 cartridge (4mV MM) and Cardas Cygnus phono cable is plugged in to assess the PrimaLuna’s MM input. I found the overall combination to be excessively weighted toward the bottom octaves and relatively dark sounding overall. This same configuration is warm through the ModWright also, but very satisfying especially with recordings which tend toward being “hot” in the upper midrange and treble.

Finally, a Rega RP6 with a Dynavector 20x2H (2.8mV HOMC)is substituted. The sound is clear and well balanced, if not as intense as I was accustomed to through the PH 9.0. Overall, I am left with the impression that the Evo 100’s MM stage is best paired with livelier, brighter sounding MM cartridges. I’m sure some of this could be changed by a little tube rolling in the MM section.

My evening concluded by switching back to the Avid and listening to Phantogram’s Eyelid Movies. Phantogram recordings fall into a special category of electronic rock/dream pop with sequenced beats. They’re intense, fun albums but are far from being “audiophile” quality recordings. Despite the average recording quality, I was again struck by the smooth, textured clarity of vocals through the Evo 100.

While the majority of Phantogram’s songs are sung by Sarah Barthel, the occasional track is sung by guitarist and producer Josh Carter. His voice often falls back into the mix, lacking nuance. Through the PrimaLuna, he emerges in a convincing, textured manner not experienced before. Very impressive.

A major difference between the ModWright to the PrimaLuna is how differently they present dynamics. The Evo 100 builds from the bottom-up, whereas the ModWright builds top-down from a higher average intensity level. High frequency dynamic details emerge from the Primaluna, as though someone were turning up a dimmer switch in a darkened room. From the ModWright, the ambient light level is higher, and the color temperature changes instead.

The ModWright PH 9.0X presents dense rock and pop recordings in a stable, lively manner with tighter, punchier bass and equally extended low frequencies. Paired with the Focal Scala Utopia Evo’s powered by a Parasound JC5, The lower octaves and overall tonal balance are more satisfying through the ModWright with rock, pop and electronic recordings, the types of music I listen to most often.

To my ear, The PrimaLuna Evo 100 Phonostage is the warmer, more organic sounding phono stage, excelling at presenting a comparatively more layered midband, remaining unflustered when complex passes occur and remaining sweet in the top octaves.

An audition of the PrimaLuna would be easy to recommend, especially to vinyl enthusiasts who gravitate toward acoustic and vocal based recordings.


Bel Canto Black EX Integrated

Sonic and Stylistic Excellence

We’re just winding up our full review of the Bel Canto Black EX integrated, and it’s been a great time. We’ve been listening to some fantastic integrateds lately, and this one’s at the top of our list. With 250 Watts per channel on tap (8-ohms, double into 4) you should be able to listen as loud as you ever need.

The Black EX is unique in the sense that even the analog inputs (MM and MC phono) are converted to high resolution digital and everything happens in the digital domain. This includes a tilt control, bass control and a high pass filter to fully optimize powered subwoofers.

Good as it sounds, the EX is compact and beautifully executed. The black finish and the quality of enclosure machining will look fantastic no matter what your décor. With everything on a single chassis, you can kiss that big rack of gear goodbye.

Please click HERE to visit the Bel Canto site and get the rest of the specs. The Black EX integrated has an MSRP of $15,500.

The Java Single Shot Integrated Amplifier

Class-D Perfection

$8,995 -$9,495 (finish dependent)

Spoiler alert. The Java Integrated is a Class D amplifier. Just in case you’re predisposed to a certain idea of how Class D is supposed to sound, you need to abandon it, or stop reading. To be fair to Java’s Martin Bell, I’ve always been Class D adverse, but I keep investigating. I didn’t like coffee until I was 50, and then one day it all clicked. Ironically, this amplifier is called the Java. Weird.

Taking advantage of the latest GaN-FET power amplifier module technology, the Java rewrites the book on whatever degree of harshness you’ve associated with Class D designs. Remember how awful digital audio used to sound? 20 years’ worth of development and it sounded pretty darn good. If you can think of this in the same vein, it makes sense.

Cursory break in with a pair of vintage ESS AMT-1b speakers immediately feels different in an ear perking way. The vintage AMTs are merciless with amplification that is even the slightest bit harsh, so this is a great torture test. Passing this test with ease, moving on to the main system with the new YG Acoustics Cairn speakers in for review is equally interesting – the Cairns are not overly bright in delivery, but highly resolving. Again, any frequency response or tonal anomalies will be instantly revealed. This is a fantastic combination.

Smooth, smooth, smooth. Smooth and tonally correct in a way that if no one told you this was a Class D amplifier, You wouldn’t ask the question. Trying a few more sets of speakers on hand vaporizes any lingering animosity towards this form of amplification. Past experience with Class D always exhibits more speaker sensitivity than normal, much like an SET tube amplifier. The result is usually brilliant or awful. The Java suffers none of these issues.

Working through everything on hand from vintage Acoustat ESLs (which due to their overly capacitive nature are tough to drive for most amplifiers) to the current Peak Consult Sinfonas that are my main reference is a breeze. Where the Peak’s are slightly forgiving in the same way that the outgoing Sonus faber Stradiveris were, the YGs and the Team Fink Kims are both highly resolving yet remain a lovely match. If you love listening way, way into a recording, this is a rewarding combination

A sonic and stylistic decision

I submit we have a lot of people out there wanting a high-performance music system, considerably more involving than a soundbar solution, more than willing to pay for it that don’t want to become audiophiles. That’s not to say that an audiophile can’t love the Java, but being that it is somewhat upgrade adverse and self-contained it may not appeal to those that constantly want to tweak things. Of course you could plug a different phonostage or DAC in, but it defeats the primary purpose.

The onboard MM phonostage delivers excellent results with the Technics SL-1200G (featuring an Ortofon Concorde Silver cartridge) and the Linn LP-12 table (with Adikt cartridge) in for review. Again, just as not all music lovers become audiophiles, not all music lovers that buy a turntable purchase thousands of albums either. We’ve certainly come across numerous end users that have 50-200 albums and are perfectly happy with that. For the random vinyl enthusiast, this will be more than you ever need to enjoy your collection.

Adding the Quadratic MC-1 step-up transformer to the MM input, taking advantage of the recently reviewed Luxman LMC-5 and Rega Apheta 3 MC cartridges proves just how good the onboard phono is, so more obsessed vinylistas can still play in this sandbox without concern. The noise floor is ultra-low, and the sense of space presented large. The onboard phono in the Java is easily the equal of anything you might find in the $800-$1,200 range and remember, no extra cables! Considering what you’d spend on four sets of mains cables and interconnects for a preamp, DAC, phonostage and power amplifier, the Java is almost free.

The onboard 24/192 DAC utilizing a pair of Burr-Brown PCM1794As in mono mode, with DSD being converted to PCM before playback delivers equally enticing results with digital files. Your favorite streamer, or laptop can be connected via USB. Keeping in with the general vibe of this amplifier, the Pro-Ject Stream Box S2 (about $800) makes the Java an effortless Roon endpoint. You can also stream from a tablet or phone via aptX Bluetooth.

Thanks to eight different finishes, the Java will integrate into any décor with ease. The high gloss and satin matt cases are only $8,995, with the five luxury wood veneer options (like our gorgeous review sample) bring the price up to $9,495. The Java you want is only a few clicks away thanks to the online configurator.

Thanks to Class D amplification, the Java only weighs 27 pounds, and offers a compact remote. Everything is CNC machined to perfection, and it feels like a much more expensive product. The input selector and volume controls both feature a backlit display, making them very easy to read.

In addition to the USB digital input, there is the MM phono input mentioned earlier, and two line-level RCA inputs. A variable preamplifier output (also RCA) is available for those wanting to add a powered subwoofer to the mix and a ¼-inch headphone jack on the front panel. Integrating with a REL Carbon Special sub and the YGs was easy as pie to configure.

As it goes with everything else, the headphone amplifier should keep you happy if you’ve got a pair of $200 – $1,000 headphones, but just like that record collection, I suspect the person buying a Java is going to make the same commitment to headphones as they are vinyl. Find a nice pair of $400 – $600 cans and enjoy. Trying a few different things from Audeze, Sendy, and Focal all went without a hitch.

The final frontier

While I haven’t had the ability to hear every Class D amplifier out there, of what I’ve heard, another commonality is their inability to achieve a neutral tonal balance. Voices always sounded somewhat electronic and grainy, as did stringed instruments. Depending on the model of amplifier, this was better or worse, but in the case of the Java, tonal balance, texture and shading is just right.
Whether listening to violins, piano, or acoustic guitar, there is a sense of rightness that allows your brain to disengage from analysis and fall into the music. I’m sure you have your favorite solo vocal tracks to investigate this with, but I lean towards Rickie Lee Jones, Aimee Mann, and Johnny Cash, merely because I’m intimately familiar with them.

Purposely heading for the most difficult tracks I know in terms of musical complexity, pushing the Java, there was never a torture test this amplifier failed. Even tracking through a higher amount of classical music than normal, delivered fantastic (i.e. fatigue-free) results. No matter what kind of music you love, the Java will satisfy you. However, if you really love electronic/techno music, the high power, and rock-solid bass control the Java delivers is very impressive. The opening track in Peace Orchestra’s self-titled album, “The Man, Pt.1” is simply enormous in its delivery through the YGs. There’s so much extension and sheer grip here, these small stand mount speakers sound like floorstanders. Ditto for Theivery Corporation’s The Richest Man in Babylon.  For those of you that love classic rock. Rush’s epic 2112 was highly satisfying through the Java and the big Peak Consult speakers. Admittedly, listening levels did exceed 90dB here!

The Java integrated amplifiers come as a single shot model, with 200 Watts per channel on tap, or the double shot model, with twice as much power. As so much of my listening is done in a 78-90dB environment, and most of my speakers are fairly sensitive, the single shot amplifier was never remotely close to being maxed out. If you have relatively power hungry (like maybe some Magnepans) speakers, you may want to pony up an extra $4,000 for the double shot model.

Sheer brilliance in every way

This amplifier is a massive success on every level. It looks fantastic, sounds fantastic, and has a balanced amount of performance in every aspect. The amplifier is far and away the most natural we’ve heard from this topology, and the functionality is just right. Should you be looking for a great two channel music system anchor, I can’t suggest the Java highly enough. Adding a table, pair of speakers, phones and some equally great cable (we used Tellurium Q Black II interconnects, speaker cables and power cord to excellent effect with this amplifier) and be all in for $15,000 – $25,000.  You can’t even buy a CPO Mini Cooper S for that kind of money.

The Java will win over two main users to be sure. The music lover lacking audiophile ambitions, and the audiophile wanting to get off the upgrade marathon. (or perhaps downsizing) But anyone who hears it will enjoy it tremendously. The Java is an easy candidate for one of our Exceptional Value Awards for 2023.

Put this one in the love column.

Power to the people – with Fuse Box!

With audiophile fuses all the rage these days, Swiss Digital has an alternative. A fuse replacement.

Taking advantage of microprocessor technology, the Fuse Box monitors how much current your component is using and then shuts it down if the parameters are exceeded. And this tech has picked up some ground lately, with a few other manufacturers following their lead.

For now, we’ve only had a chance to try it with our LSA VT-150 integrated (you have to have it configured to your individual components) with excellent results. We’ll have a full review in issue 117, but suffice to say that this is an interesting upgrade, and a methodology that we wouldn’t be surprised to see being an OEM product at some point. Let’s face it, wire fuses are pretty old tech.

A Single Shot of Awesome From Java HiFI

You know you want this. I want this.

For every audio enthusiast that has had to listen to a friend, partner, or roommate complain about the overly industrial look of the gear we love – bam. Here’s your answer. The Java integrated you see here is the “single-shot” version with 200 Watts per channel of power. (the “double-shot” has, you guessed it, twice as much power)

For $9,495, you get a magnificent looking product that will look great in any environment, that sounds great thanks to careful design and utilization of the latest technologies. We’ll have the full review done shortly, but suffice to say it’s a winner. Also included is an excellent MM phono stage, and a USB/Bluetooth DAC.

Pair it up with your favorite speakers, as power will not be a limitation, and place it in your room where it will get a lot of attention. And it will. Bonus points: Java lets you customize the look to your preference, just go to the configurator section of their site. Just click here.

YG Acoustics Cairn

In case you hadn’t noticed, the new range of speakers from YG Acoustics (the Peaks series) offer wood cabinets instead of the aluminum you’re used to from this high performance manufacturer. This small two-way, stand mounted system carries an $8,500/pair price tag (stands optional – $1,500/pr.) and deliver big speaker performance. Here in our 24 x 36 foot listening room, they offer an immersive, three dimensional sound stage that will pull you in like your favorite panel speakers. But they have big dynamics too!

Of course, a pair of small woofers can only move so much air, but what’s here is good. Really good. Tracking through a major set of 80s classics, chock full of deep, synth-bass, the Cairn’s deliver a stunning performance. And, YG offers a matching subwoofer, which we’ll have in for review soon. With a rated sensitivity of 86dB/1-Watt, they prove incredibly easy to drive. In combination with our favorite little tube amp, the Mighty from Lab 12, the Cairn’s still really rock the joint.

You might think YG has cut corners to produce a wood cabinet, but after a recent visit to the factory to observe their manufacturing process (which feels a lot more like a Formula 1 parts supplier than a speaker manufacturer) they point out that because wood is a bit more of a variable than aluminum, it’s actually more work to make their thick aluminum front panel fit up to the cabinet. No compromises have been made whatsoever.

In the end, it all serves the music. Having had a chance to hear the entire Peaks range, YG has masterfully combined everything they’ve learned up until now, and incorporated some new tech to build an entire line of speakers that are approachable in price and implementation. They work equally well in the context of a tube or solid-state system.

Stay tuned for our full review.

The Heretic AD612 Speakers

If you read our review of the Heretic AD614s, you know how much I love these speakers. Always on a hunt for a great pair of high efficiency speakers, the Heretics succeed brilliantly. The only major difference between the 614s (which actually use the same 12″ coaxial driver) and the AD612s you see here, is cabinet volume.

The increased cabinet volume allows the 12″ ported driver that pays homage to the Altec cabinets used back in the EMI/Beatles days to go a bit deeper. 35hZ, vs. 40 for the 614s. Fortunately, they can be placed fairly close to the wall, so you can pick up a little bit of room gain. Wall voicing is a great thing for the Heretics – speakers up against the wall looks super cool, and that extends the useful frequency response down to about 32hZ.

Available in a few different finishes, these speakers are gorgeous no matter how you configure them. Our full review will be live in issue 117, but thanks to their 97dB/1-watt sensitivity rating, the Heretics are perfect for low powered tube amps. The Pass Labs First Watt amplifiers also make for an excellent, highly musical pairing.

The Heretic AD612s are incredibly amplifier friendly, and will deliver good results with nearly anything, much like my other favorite speaker, the legendary Quad 57, the absolute right amplifier takes them to a completely more engaging presentation. So the AD612s may just send you on an amplifier hunt!

Very enthusiastically recommended and #toneaudioapproved. You’ll be seeing a lot more of these in the years to come.

Focal Announces Theva Speaker Lineup

Always on the move, improving their products, Naim has announced today that they have replaced the very popular Chora Line with their new Theva speakers. This is a full lineup, with products for 2-channel and theater users. Here’s what they have to say about all the changes incorporated into the Thevas. It’s pretty extensive.

Focal listened and with consumer feedback is excited to present Theva, a new line of Hi-Fi loudspeakers comprising six products that deliver uncompromising performance and design.

Made in France in Focal workshops, all the speaker drivers in the Theva line are born of Focal’s unique know-how. They incorporate its Slatefiber technology, a cone made from recycled non-woven carbon fibers and thermoplastic polymers from discarded aeronautical and automotive parts. It delivers excellent performance, reproducing a dynamic, rich and balanced sound.

First seen in the Chora line, this cone has proven its worth across numerous products and several divisions, since our engineers have used it to develop the Alpha Evo studio monitors and even the Slatefiber in-car kits.

Also made in France, the Aluminum/Magnesium TNF tweeter – already present in the Chora loudspeakers – offers a mellow, clear treble. With its outstanding performance, it was the obvious choice for Theva loudspeakers.

The finishes for the Theva loudspeakers are inherited from the Chora line, with considerable improvements. They are more modern, to blend even more seamlessly into any interior. The pure, elegant look of the Black, Dark Wood and Light Wood finishes enhances any room, as well as offering an even closer coherence with our other loudspeaker ranges. Each Focal line has its own aesthetic, while together they form a harmonious catalogue and unique signature.

After Chora, every detail was reviewed and redesigned to create loudspeakers that are robust and refined from every angle.

Here are the key areas Focal concentrated on with Theva:

An additional front panel, for the perfect finish and no risk of detachment on the front.

An increased perceived value with a metallic, screen-printed Focal ring around each speaker driver. It also ensures Theva is coherent with all our other lines.

A vent now placed on the rear of the loudspeaker, for a sleeker finish on the front. This also reduces the size of the enclosures, particularly the one housing the Theva N°1 bookshelf loudspeaker, which is much more compact in comparison with Chora N°1.

A fold in the vinyl at the back of the loudspeaker to avoid any detachment.

The addition of a slimmer loudspeaker to the range, Theva N°2, perfectly suited for smaller settings, with an even more attractive profile.

A light base for the Light Wood versions for even more sophisticated products. Likewise for the grills, designed to coordinate with the finishes: a beige grill for the loudspeakers with a light finish.

A tweeter minus its grill and surrounded by a chrome ring for an understated front piece.

The Focal flame beneath the speaker drivers on all the loudspeakers in the Theva range.

The Puron Power Filter

One of the most important things in your audio system is the quality of the power you are feeding it. Before spending a ton of your hard-earned cash on exotic audio accessories, consider sorting out the power first. The more artifacts you have in the power line, the more noise creeps into the audio signal.

The Puron is a small device that is not a “pass-through” device like a standard line conditioner, and it can be used in tandem with whatever current power conditioning you might be using. It looks somewhat like an old metal encased rectifier tube (for those of you old enough to remember that kind of thing) and is meant to be plugged into the same circuit as the components you are using, whether you have a line conditioner or not.

We are in process of trying this in a number of different environments and systems to give you a full report, but for now, the Puron proves successful.

The first trial in our main listening room, only yielded a small, but definite result on a system consisting of the T+A Caruso R all in one, and a pair of vintage ESS AMT1-b speakers, with Tellurium Q Black power and speaker cables. This was chosen because this system has a bit of a high frequency edge to it. The Puron definitely took some of the glare out of the presentation, and actually had more effect the following day after being in the system for about 30 hours. (Which incidentally is what Vera-Fi says needs to happen for optimum result.)

To put things in proper perspective, the TONE studio is a metal clad building (kind of a natural faraday cage), with it’s own dedicated power, attention paid to grounding, and Cardas outlets installed where gear plugs in. There is no wi-fi in my office – even the iPad is hardwired, and there are no wall wart or switching power supplies. Finally, there are no light dimmers of any kind. So, it’s fairly grunge free out here.

The house is a different story. Multiple appliances, wall warts a plenty, Hue light dimmers, and wifi everywhere. All in the context of a 60-year old house. The bedroom system consists of an LG 80” TV and a pair of Totem Kin Play Tower speakers. Nothing fancy, by any means. This was an immediate change for the better. Just watching the last two episodes of Picard shows less pixelation and noise in the blacks. Seriously, I’d buy one just for this. However, it really did clean up the sound coming through the Kin Plays by an order of magnitude.

We’d really like to try this in a few more configurations. But for now at $250, I can’t suggest this one highly enough. – Jeff Dorgay


New Wyred 4 Sound Power Conditioner

We all know how good quality power delivery is to your audio system.

The new ProPowerStream from Wyred 4 U/Wyred 4 Sound comes in at an introductory price of $699 with one of their power cords included – A nice touch. With a 1000 Watt capacity (max. 1500) this is a great addition to line level components and smaller integrated amplifiers.

In addition to the line conditioning circuitry, the PPS also incorporates a DC snubber, which can eliminate harmful DC from getting into your system. Even a little DC floating around on your mains can wreak havoc with your system, and some very expensive conditioners don’t address this.

We’ve got a full review under way, but initial use in our headphone system and system three (which consists of a Naim Atom Headphone amplifier, Technics 1200 table and Parasound phono pre) instantly reveal a lower noise floor and more clarity up on top. But more listening is needed to give you a more in-depth report.

However, in a world where first impressions are everything, this is an excellent product and worthy of your attention. (and credit card, hahahaha)

RAW Power – 50th Anniv. Legacy Edition

Listening to the 50th anniversary edition of this punk classic raises a few questions: How did I get this old? How did Iggy make it this long? But the one question I can answer definitively is how does this record stand up half a century later?

It still rules. With multiple alternate takes, mixes, and outtakes, Raw Power is still a blast, that sounds best when you blast it. The additional live tracks, recorded in Atlanta, Georgia in 1973 convey the live Iggy experience of the period, and flesh out the perspective of this record nicely. This is an original DIY production to be sure.

Bruce Dickinson joins Iggy for engineering and producing credits, and it’s clear they took as much care as you can take on a punk record to make sure this iconic pressing is preserved for all time. Everyone else needs to write Iggy Pop a check.

The LSA VT-150 Integrated

With the backlit output meters bouncing to the sound of Massive Attack, cranking up the VT-150s bias to the “high” position and plugging in a set of KT150 tubes proves to be a great move to get that club feeling. Our Team Fink Kim speakers are relatively easy to drive and taking advantage of their variable damping factor technology allows an incredibly good matchup to this tube amplifier, delivering solid bass.

Both Jerold O’Brien and I really enjoy the lower powered VT-70 from LSA. It’s a great entry level tube integrated that ticks all the boxes. Good build quality, great sound, and tubes that are relatively easy to come by. However, if you’re a tube lover, you know a pair of EL34 output tubes can only take you so far – lovely if you can live with 35 Watts per channel, but not the right tool for the job if you have speakers that require more power to do their thing. Or, you really like it LOUD.

Variable output

VSA now gives you a way to get more power, and if you use this amplifier as a monoblock, way more power. And options, you like options, don’t you? While you can drop a set of KT88s in the VT-70 and crank up the bias a bit, it won’t deliver that much more power, but the VT-150 thanks to its larger power supply and more robust output transformers (and more weight…) will deliver 60 Watts per channel in stereo mode at the lower bias setting.

Where PrimaLuna offers this as a switch-controlled function on some of their EVO amplifiers, the higher-powered options on the VT-150 require some manual labor. But this is what gets you a 60-100 Watt per channel integrated for an introductory price of $2,499. If you aren’t constantly tube rolling, this won’t be an issue.

Should you desire 80 Watts per channel, or even 100 Watts per channel with a set of KT150 tubes, the bottom cover can be removed, and jumpers replaced to supply the output tubes with the necessary current to deliver the additional power. Keep in mind, running the KT88s (or KT120s, if you go that route) at the higher bias results in shorter tube life. It’s easy enough to see what you prefer and set your VT-150 that way. If 60 Watts per channel gives you enough juice to light your speakers up, stick with the low bias setting and enjoy longer tube life.

Whether you are new to tubes, or familiar with the breed, biasing the output tubes is very easy – the output meters double as a bias indicator. Take a quick peek at the well written manual and follow the instructions. You’ll be an expert in no time. As with any tube amplifier, re-check the tube bias again after a week or two and then in a month. After that a cursory look should be all you need, the tubes should not shift much after the first 30 days or so. When you can no longer bring them to full bias anymore, it’s time to replace.

Basic configuration

Where the VT-70 offers a basic remote control, the VT-150 is no frills and no remote. Where the VT-70 offers three single-ended RCA inputs, the VT-150 has one RCA input and one XLR. Around back, you’ll see a switch that turns the amplifier into a monoblock, and delivering more power. Instead of having 4 and 8-ohm speaker taps the VT-150 now has 8- and 16-ohm taps. None of the speakers on hand for the review had major impedance drops so there were no issues with this amplifier in stereo mode.

For those seeking the maximum amount of sonic engagement with the least number of superfluous additions, the VT-150 is the way to roll. They’ve eliminated the remote control, no LED light in the volume control, and have kept all functionality to the bare minimum. The front panel is nicely finished, as is the volume control and chassis – an amplifier you’ll be proud to own, no doubt.

However, when producing product at this price point, every ten dollars affects the bottom line. In this case, the frills eliminated have been put into the quality of the output transformers and the components underneath the chassis. A few other tube integrateds offer completely point to point wiring, where the VT-150 has a mixture – they are all way more expensive. Careful listening reveals this amplifier is without sonic compromise, at this price. Considering that the McIntosh LB200 with optional rack mount handles will set you back $2,000 and it’s only a light box, the VT-150 must be one of the most stellar values in high end audio. Another $500 gets you a 80 Wpc integrated amp! Woo hoo.

More about tubes

The VT-150 arrives with a tube cage in place, but if you can avoid using it, few things in audio beat a bunch of glowing tubes. Much attention has been given to the output tube choices at your disposal with this amplifier, but thanks to the input/preamplifier stage using a pair of 6SN7 and 12AU7 tubes, you can tube roll to infinity.

Manufacturers rarely want us to discuss the benefits of tube rolling, especially substituting NOS tubes because this is not a consistent item, and often without repeatable results. Hence, manufacturers tend to design around tubes that are readily available. However, this amplifier circuit is well designed, and should the urge strike to swap tubes, there are sonic rewards to be had. It will depend on how maniacal you choose to be, but let it be said that should you feel like chasing down a few primo 12AU7s and 6SN7s (or maybe have some on hand already) it’s worth your while to experiment.

Ditto for the output tubes. The KT120 is not my favorite output tube, as it tends to sound more etched, but that doesn’t mean it won’t be the perfect match in your system with your speakers. Leave bias jumpers at the lower setting and set bias to the higher end of the range. The KT150s will deliver the most output, however the presentation is a different one than the KT88s produce.

When driving a pair of vintage Acoustat 2+2 speakers, the extra output and high-end snap, along with a pair of Nordost speaker cables brought those old ESLs to life in a way that’s never been done with a modest tube amp. When driving the XSA Vanguard speakers, the KT88s even at the lower bias setting is incredibly engaging. Finally, keep in mind that the amplifier sounds great out of the box. Tube rolling is not a necessity; however, this amplifier responds well to small changes. So to be clear, the VT-150 delivers top performance out of the box with the stock, factory supplied tubes, however those inclined to investigate premium tubes will be rewarded as well. This great for two reasons: it gives you a chance to easily improve your system as your involvement grows, and it shows a circuit that has been designed beyond meeting its immediate price point.

The finer points

Because the VT-150 uses a pair of input transformers to offer balanced inputs, this input will provide a slightly warmer, less dynamic sound than the RCA inputs will. The upside is this amplifiers’ ability to be fine-tuned to your music collection and/or listening habits. These are miniscule differences but make a difference nonetheless when using a balanced source.

Listening to the VT-70 and 150 side by side for some time, it’s important to point out that you are not merely getting more power when stepping up. More refinement awaits you with the VT-150 too, a sign of great designs. The bigger amplifier is more composed on top, more controlled on the bottom, and it resolves a decent share of increased inner detail too.

The VT-150 produces a very clean, fast, detailed look into the window of your favorite recordings. Comparing it to more expensive amplifiers on hand from Audio Research, BAT, Octave, and PrimaLuna, the VT-150 holds its ground. It is not a giant killer. The refinement afforded by the 10-20k amplifiers is still supreme. However, the way this amplifier nails all the musical basics at an equally commanding level will surprise you.

Tracking through a wide variety of different music is a joy with the VT-150. It is dynamic enough to play classical music or heavy rock as loud as you need yet offers great linearity at lower volumes. Even listening to the CSN debut album on MoFi at very low levels with the Dynaudio Confidence 20s is incredibly engaging. Yet cranking the volume way up for some Public Enemy and Slayer proves it delivers the goods.

in addition to having solid, controlled extension on both ends of the frequency scale, this amplifier can generate a large sound field in all three dimensions. There’s a lot of “vacuum tube magic” going on here, to be sure.

And, putting a $2,500-$3,000 amplifier in the context of the $7,500 to $15k system it is more than likely going to end up in will leave you thrilled with the purchase. If you’ve been dreaming of investigating a tube amplifier, I can think of no better place to start your journey. Perhaps at some point, we will commandeer a second one to investigate how these perform as monoblocks. For now, staffer Jerold O’Brien will be using this one on a daily. His daughter took the VT-70, so how can you argue with that?

Highly recommended.

Our System of the Year for 2023

We’ve decided to do something different this year…

How about giving out an award at the beginning of the year and start out on a happy note? Bam. If you’re looking for a great all in one, turnkey system that will serve up music in every format, we suggest this setup.

Also, just so we’re CLEAR – we do not advocate putting a speaker on the same shelf as a turntable… Just trying to take a pretty picture here. PS: Click here to go to Design Within Reach if you’d like to purchase the Nelson Bench in the photo.

The rest of the system is built around The T+A Caruso R ($4,250) and the XSA Labs Vanguard ($795/pr). We’ve rounded it out with a Technics SL-1200GR table ($1,799 without cartridge) the iFi Zen Phono ($199) and a pair of Tellurium Q Blue II speaker cables ($149 for a 2.5m pair). ($225/pair for the 1M RCA interconnects to the iFi Zen)

Taking Ethernet Performance Higher

The folks at Network Acoustics have developed their Muon Pro Ethernet Filter and Streaming Cable, claiming to eliminate noise in the network line. Initially developed for the Pro Audio world and handmade in the UK, we will be anxious to hear how this (Approx.) $2,000 bundle cleans up the sound.

The Naim CD5 Si CD Player

What, a CD player in 2023? Shut up.

If, like us, you still enjoy the CD format, and why would you not? This modestly priced player from Naim, leverages a lot of tech from decades of producing some of the world’s finest digital players, with and without disc transports.

Priced just under $2,000 ($1,990 actually) the CD5 Si delivers the goods. It doesn’t stream, it doesn’t let you access the (excellent) internal DAC, it just plays CDs. And it does a cracking job. If you are still a CD lover/collector who’s been wanting to replace that 10 or 15 year old player that you know is about to fail, drop what you’re doing and buy a CD5 Si right now. You’ll be glad you did.

As you unbox the CD5 Si, you instantly realize that this feels like a much more expensive component, from the weight of the enclosure, to the immensely tactile feel of the buttons, to the bank vault solid transport drawer. Put your favorite disc in and press play. Regardless of where you are on your digital journey, you’ll be enthused.

We’ve only just begun the full, in-depth review, and we can tell you this one’s going to be one of our first Exceptional Value Award winners for 2023.

The REL No. 31 Subwoofer

Tracking through a time-worn favorite, The K&D Sessions, the very definition of the lower bass notes being delivered is stunning, just coming from a six-pack of REL No.25 subwoofers I lived with for two years. I loved em’ but at the end of the day, they were just a bit too large physically for my room. (Though REL’s John Hunter had them set up to perfection in said room).

Yet here we are – a smaller cabinet delivering even better results for $500 less. (the outgoing 25s were $7500 each.) With a Santa Claus-like twinkle in his eye, he says, “you really should hear what we’ve done with the ($10k each) no.32. Merely extrapolating from what I’m experiencing with the 31 and have from the 25s, I’ll bet for someone with an even bigger room, they are amazing. For now, the No.31s head back, as they have dates already scheduled with other reviewers, and I’m doing some remodeling here. If the planets stay aligned, the TONE listening room will increase to 24 feet by 26 feet – which will warrant revisiting the No. 31s in a six-pack configuration next year.

Having the pleasure to meet some of the best minds in high-end audio over the years always leaves me with the same question: how do you keep making products that already deliver a rarefied level of performance better? Yet, they always do.

Keep in mind that engineers and designers live to push the envelope. It’s what they do, what they are trained to do, and what they are paid to do. Much as the grouchasauruses like to think that “it’s just all marketing,” the legitimate manufacturers have a plan. Some (Audio Research comes to mind, bringing a new model out every 2 years or so, then an “SE” model 2 years later.) Others like Nagra and Luxman only make a change now and then – yet they all take the approach that significant change must occur to warrant a new model. 

For another thought on this process, read my blog piece, “What you have isn’t rubbish,” here.

Cursory comparison

Mr. Hunter goes to great lengths explaining all the things that make the new (No.31 and No.32) models a major leap in performance from the old models (No. 25 and G-1MK.II). It only takes the first bass drum stomp from Shelby Lynne’s “Just a Little Lovin” to reveal the increased resolution his new baby produces. Having spent a fair amount of time with the recent Carbon Special, the No.31 takes the advances in driver, cabinet, and crossover made there to another level. And yes, I still have a Carbon Special here to compare. Going back to the Serie S 510s (also here for comparison) shows off a solid lineage, but comparing the S/510 to the Carbon Special or the No.31 is another step down in resolution. That said, a six-pack of S/510s remains formidable because of the spatial qualities only a six-pack provides.

I’ll stick my neck out and say that the Carbon special gets you about 80% of the way there, with a more traditional (i.e., box-shaped) enclosure that is smaller and lighter. The REL website claims that “the No.31 delivers the No. 32’s sound quality, build quality, and thoughtful features with a more compact footprint.” I couldn’t agree more.

Just as a particular breed of automotive enthusiasts thinks a 500hp Porsche GT3 is the way to go until they have to drive through a Starbucks window, some will settle for nothing less than the No.32s. But just as a GT3 can only be truly experienced on a long stretch of road with no law enforcement for miles, or a race track, I submit that unless your room is truly massive, you can live happily ever after with the No. 31. (Or a pair, or better yet, a six-pack) Or a Porsche Cayman GTS 4.0. Just saying.

Judging on its own merits

Forgoing the comparisons picture for a while, the No.31s deliver a prodigious amount of low-frequency output – but many subwoofers can do that. Where this product truly excels (like the other top RELs before it) is the level of definition and texture in the lower registers and the life they breathe into the upper ranges of your hifi system. No other sub I’ve reviewed does this to anywhere near this extent.

The No.31 has a long-throw 12-inch carbon driver, 900-Watt amplifier (this is the same 1000-Watt amplifier used in the No. 32, but limited to 900 Watts because of the No. 31’s 12-inch driver having slightly less ultimate excursion than the 15-inch unit in the No. 32) the majority of low-frequency extension will be provided by a single unit, but that’s not the whole story. Where the Carbon special’s 12-inch driver shares core technology with the 12-inch driver in the No.31, the latter’s driver is much more robust, allowing more output and more extension. Being ADD for a minute and thinking about carbon fiber (something I think about nearly all the time anyway), check out the super zooty carbon fiber REL badge on the top of the cabinet. Woo hoo. And check out the slight edge curvature on the cabinets. Subtle but better.

Going to a pair, as we’ve done in this review, helps to smooth out the bass response in the room, making the single woofer work less at pressurizing the room. Thanks to REL’s dual parametric filter, these subs are easier to tune to your room and main speakers. For those not familiar with RELs approach, they prefer to take the high-level from your amplifier’s speaker outputs via a Speakon cable/connector and run your main speakers’ full range.

Even better, thanks to RELs gorgeous, yet highly functional remote, you can adjust everything from your listening chair, which really helps the setup process. Be sure to move that little “lock” button to the lock position when finished, so prying hands will not undo your hard work. If you’re new to the top REL subs, it’s also worth mentioning, (especially if you have more than one) make use of the LED readout in the upper right corner and take note of all your settings. This will always make going back to your starting point much easier, should you explore different settings at a later date.

This has a couple of advantages. They claim it’s much easier to integrate with your main speakers – and I agree. I’ve set up at least 40 or 50 subs from REL and several others over the last 20 years here, and this still is the easiest way to blend sub and main seamlessly. Are you turning the sub up, down, and sideways from one album to the next? You’ve got the setup wrong, and I’m only saying this as someone from the other side of that same canoe.

Second, by using the output of your amplifier instead of the preamplifier, the low-frequency flavor of your system stays precisely the same. I’ve tried a few RELs via the preamplifier inputs to prove this point, and it’s still pretty good. However, it’s not as good (in every way) as it is when going speaker out. The No. 31 is faster, tighter, and more extended when connected via speaker outs. This also has the benefit of not needing another pair of incredibly long and expensive interconnects.

More listening

Because this isn’t my first rodeo with REL, They are up and going pretty quickly. As the REL mothership in the US is just 600 miles down the I-5 freeway, Mr. Hunter is kind enough to fly in for the day and double-check my work. With some careful fine-tuning on his part, the delta with REL in to REL out is even greater than before, and we run down a handful of familiar tracks we both know well when setting speakers up. (Yeah, that means the horse song.)

Like the No. 25s before, the No. 31s prove a major upset to office productivity. The improvement of our reference Acora SRC-1s is tremendous. These fabulous speakers now go bigger, louder, and deeper. While Ella Fitzgerald is the usual “go-to” for music with relatively little low-frequency content, this time, it’s a Supremes superset. And again, even with relatively sparse LF information, the soundstage swells in size dramatically. Diana Ross’ silky voice has more body than ever before. It’s pretty dreamy, and when the RELs are unplugged, the soundstage collapses.

For those unfamiliar with the Acoras, they are fast, offering near electrostatic-like transients. Like the other top RELs we’ve tried, the No. 31s can easily keep up with your favorite ESL or planar speaker. 

Pumping the bass way up, the jumpy, funky bass line in the Average White Band’s “Cut The Cake” pushes my chest cavity in as the volume control goes up. Hunter was headed home at 5 p.m, but I was up with a long list of bass-heavy tracks from RUN-D.M.C., The System, K.C. & The Sunshine Band, and some Prince until about 2 a.m. In the world of stuff, there are a few things I never get tired of, Porsche manual transmissions, the gentle click of a Leica rangefinder camera, and the way a REL subwoofer improves a system. It’s never less than extraordinary. 

The following day was reserved for more heavy rock and jazz. Jaco Pastorius, Stanley Clarke, and Charlie Hayden all sound more similar than different on a lesser sub, but with the No.31, you can easily hear the distinct sound their instruments and playing styles make. Rather than bore you with a long playlist of tracks, the REL No. 31 excels at its function. Even when playing arena rock at brain damage levels, the RELs never run out of excursion.

At $7,500 each, these are not inexpensive subwoofers. However, if you’ve invested $30k to crazy money in a pair of main speakers, will you bring up the bottom with an inexpensive pair of subs? Whether you choose one, two, or six – you will be impressed by the added dimension the REL No.31s can deliver to your system.

And, we’d like to mention that the No. 31 was awarded one of our three Masterpiece awards at the end of 2022.

Luxman L-507Z Integrated Amplifier

Relaxing with Elvis Costello’s Painted From Memory on the turntable, it’s almost tough to believe that the source is an integrated amplifier, not a $100k rack full of separate components and a $30k loom of mega cables. When music lovers that want high performance yet do not want a rack full of gear, a pile of cables, or the inconvenience of vacuum tubes, ask me what to buy, my answer is always Luxman. There are a few others I’m very fond of, but if you want the phono on board and prefer to keep your DAC as a separate component, Luxman is my personal favorite. And Luxman offers a few incredible digital boxes to keep it all in the family.

I enjoy a few other excellent brands as much, but the combination makes Luxman integrated amplifiers so unique. The combination of every section, performing at an equally high level, to be precise. Coming up on its 100th birthday in a few years, Luxman is a company of constant refinement and engineering excellence. Everything they improve is purposeful, and the new products always outperform the old, leaving you thinking, “how did they do that?”

External beauty

Weighing 25.4kg/60 pounds makes the L-507Z big but not unyielding for a single person to unbox and carry. I suggest some gloves; just because that front panel is finished to such a high standard, you wouldn’t want to scratch it. As with every other Luxman piece that’s been through here, you don’t realize just how lovely this amplifier is until it’s sitting on the shelf/rack of your choice. It’s much like examining a high-resolution photo captured with a high-quality digital camera. The more you zoom in, the more you can see the fine details and level of finish. Perhaps it’s my imagination, but it seems like Luxman has refined their already excellent level of finish on the L-507Z.

This product is beautiful to behold and contributes significantly to the pride of ownership and happiness with writing the check. I’ve only seen this level of fine finish on Burmester and Boulder gear – both cost a lot more than Luxman.

All the usual controls you expect from a Luxman amplifier are here and in the same place they always reside, so the level of familiarity is a great thing. However, a few new features are clearly apparent. In between the output level meters, a seven-segment LED numeric readout resides, letting you know at a glance from across the room how high the volume level is. 

The tone controls are still present; if you’re a complete purist, ignore this paragraph. However, if you’ve longed for a bit of boost or cut at the frequency spectrum extremes, Luxman’s implementation is perfect. The bass and treble controls are gentle in their effect but very handy on a somewhat flat or tinkly record. It’s also convenient for headphone listening – especially if you have a collection of headphones. The tone controls go a long way at adjusting minor differences to make your personal listening that much more enjoyable. There is also a new 4.4mm “Pentaconn” jack on the front panel that Luxman says allows “quasi-balanced” operation because of its separate right and left channel grounds, resulting in better left to right separation. Unfortunately, we didn’t have a pair of phones wired this way, so we were unable to fully investigate. Here is some more information about the Pentaconn connector:

However, our usual stable of phones from Audeze, Grado, Sendy, HiFi Man, and Focal all worked well, indicating a substantial amount of current drive from the 507Zs headphone amplifier section.

Around the back, in addition to the analog phono input, there are four RCA, line-level inputs, and two balanced XLR inputs. Luxman allows you to invert the phase of these inputs in case you have an external source (like Burmester and a few others) that doesn’t use the standard pin configuration. For the first time, 12V trigger and control jacks are also available for anyone needing to blend their L-507Z with home automation.

Subtle smoothness

With only one class-A amplifier in the lineup (at least for now), Luxman is further embracing class-AB topologies, no doubt, in an effort to be more green. Yet, the level of smoothness and refinement always associated with their class-A amplifiers is here at a nearly equal level. The class-A Luxman amplifiers, particularly the L-590II, is slightly warmer but also somewhat less dynamic. A fine distinction but one to be aware of.

Connected to a pair of Dynaudio Confidence 20 speakers and a six-pack of REL 510 subwoofers, the combination is stunning. Because the REL subwoofers perform their best when connected to the speaker level connections, the Luxman’s L-507Z’s front panel speaker switch is incredibly handy. Being able to switch the subwoofers in and out like this makes setting them up that much quicker. It also made A/B comparisons here very easy to get on with.

With 110 Watts per channel (into 8 ohms, and 210 per channel into 4 ohms), precious few speakers are off limits. Trying them with everything from the (86dB/1-Watt) Harbeth Monitor 40XDs, to a pair of (96db/1-Watt) Heretic 614s, Magnepans, and vintage Acoustat ESLs was a breeze. Everything on the list was able to be played as loud as I’d ever need to listen to music. Even the notoriously power-hungry Magnepans deliver an excellent performance.

The lower octave, with or without subs, is solid, with texture and finesse. Starting with the Supreme Beings of Leisure’s 11i (which has notoriously floppy, whumpy bass) and transitioning to Kruder & Dorfmeister, finishing up with some Neu! all were engaging and powerful.

Subtle details

Luxman products personify the “greater than the sum of their parts” philosophy. Building on the technologies that have made their components so well known in the first place with a new 88-step LECUA 1000 attenuator circuit (also used in their top separate components), along with improvements to power supply design and even the circuit board layout all adds up to higher performance.

Where most of the technological improvements will be apparent the minute you turn on your L-507Z, most of them are inside, where you can’t see them. The new LIFES (Luxman Integrated Feedback Engine System) replaces the previous ODNF circuitry and cuts the low amount of distortion in half of earlier models. Again, the technology from their separates is converging in the L-507Z – there’s a level of musicality here that you might associate with a much higher price tag.

You don’t notice this quite as much when pushing the power output needles into the red playing Slayer, but it’s instantly obvious when switching the faire to something more subtle like acoustic instruments. A few reasonably long listening sessions comprised of solo piano, violin, and acoustic guitar had me wondering if this was not a class-A amplifier after all. Good as this amplifier is, the level of midrange integration with acoustic instruments is tremendously good.

The most significant difference is in the shadows or the quiet passages. Where the outgoing L-507uX also produced 110 Watts per channel, this amplifier is not only more silent, it has more low-level resolution. Fine details fade more gently into the backgrounds, with a greater sense of the information at your disposal. Whether listening to analog or digital sources, you’ll hear more.

Fantastic phono

Luxman claims an improved phono section in the L-507Z, and again, I can’t help but agree. With a .3mV/100 ohm spec, the Luxman integrateds have always been perfect for a Denon 103R cartridge, as well as the Dynavector 17DX Carat. Both proved to be a great matches. It’s also a perfect match for Luxman’s new LMC-5 MC cartridge. We’ll have a full review shortly. Setting the stylus of the Dynavector down on Al DiMeola’s new Saturday Night in San Francisco is breathtaking. Hearing these three guitar virtuosos come to life in front of me again has me wondering if I’m really listening to an integrated.

Good as past models have been, this is another step up. Again, putting this amplifier in the context of a $20k – $50k (or even maybe a little more) system as its hub, I could easily see pairing this with an excellent $3-10k turntable and calling it a day. 

Always a joy

In nearly 15 years, I never tire of unboxing a Luxman product. The care in the build that extends all the way to the packaging is a wonderful thing, in this age of ambivalence we live in. The balance of cost, features, aesthetics, and performance are top shelf. Just as McIntosh and Naim have feverishly dedicated to the brand supporters, Luxman is no different. If the combination provided by the 507Z ticks all the boxes on your list, there’s no better choice. 

I only have one complaint about the 507Z; it’s both selfish and personal, so it probably won’t apply to most of you. Since Luxman offers an MM and MC phono option, I truly wish they would offer two phono inputs – one MM and one MC. Come on, there are two headphone outputs on the front panel. That would truly make a 99.9% product 100% perfect.

Keep in mind this is the first of the new “Z Series” integrateds from Luxman, so it will be interesting to see how they rollout the rest of the lineup. Based on the past Luxman models we’ve owned and reviewed, I’ll bet they will be equally fantastic. Stay tuned.

The XSA Labs Vanguard – a new paradigm.

In case you’re wondering, XSA stands for “eXtremely Sexy Audio,” and the Vanguard monitors you see here, done up in bamboo are certainly that. Those of you that work with wood on a regular know how hard bamboo is to work with and get it to look right.

Bamboo is the carbon fiber of woods – it’s hardness is much tougher to cut and machine to tolerance – one mistake and you’ve blown it. Careful inspection of the cabinet corners and the cutouts for the drivers is a real work of industrial art. Sexy indeed.

Listening to the rich vocal harmonies in Crowded House’s Woodface brings the capabilities of this great little speaker immediately. They deliver a huge sound field, that is deep and wide. Top to bottom is pretty good for such a small speaker as well. With grilles removed, it’s easy to see the homage to the LS3/5a, but I suggest that this is a different beast. And for $799 a pair, a beast you just might want to welcome into your home.

The Vanguard is about an inch and a half deeper than the LS3/5a cabinet; designer Dr. Viet Nguyen makes this choice to get a bit more bass extension from the 5.25” treated paper cone woofer. Moving from boomer rock to 90s obscurity, with Crash Test Dummies’ “Just Chilin’” reveals where the bass rolloff is – but again, this is an impossible feat for any small speaker. However, in a smaller room the fundamental is still there. Moving back almost a decade to the Dummies’ “Superman’s Song” is where the Vanguards shine. They keep lead singer Brad Robert’s deep voice perfectly blended with the light background vocal of Ellen Reid.

Playing music that doesn’t push the Vanguards out of their sweet spot is a revelation. Winding up this listening session with Elvis Costello and Burt Bacharach’s “I’ll Never Fall In Love Again,” from the Austin Powers soundtrack is truly groovy baby.

A Bit of back story

The BBC LS3/5a monitor has been a staple of small room audiophilia for decades. This diminutive monitor, in a small-ish room with the right electronics does such a fantastic job achieving a natural sounding midrange, you forget about what it doesn’t do. Because the BBC engineers were using it as a location recording monitor, their goal was to get the voices right. I’ll bet they had no idea their creation would become such a cherished thing. Measurement geeks will complain to the stars about a lack of bass and treble extension, and rolled off highs – yet when you sit in the chair and listen, it’s hard to not come away amazed and smiling.

There have been a number of BBC licensed LS3/5a variations over the years, all with a somewhat different sound. Several manufacturers like Harbeth, have done their own updated variation on the theme, and while not following the design exactly, keep with the spirit. Most of these speakers run in the $2,500 – $3,500 range and are all well-crafted. Just as we can have a heated discussion about which version of the 12AX7 tube is “the best,” the same can be said for the LS3/5a and the speakers it’s inspired.

Back to the future

While it’s always fun to respect the past, drivers and crossover components have improved dramatically over the years, and what used to cost megabucks is now much more approachable. Dr. Nguyen’s hard work came to the attention of Mark Schifter, (an industry vet  who’s influenced a number of great brands over the years) who is not only a main collaborator on this speaker, but the LSA 50, 60, and 80 – another group of speakers offering tremendous performance and value.

If you’d like a little bit more tech perspective on the Vanguards, there’s a lively discussion over at, illuminating more of Dr. Nguyen’s design decisions, and of course, measurements. However, measurements don’t tell the whole story, and they don’t speak to the natural tonality that these speakers deliver. Just as most reasonably priced EL-34 tube amplifiers deliver a slightly warm overall sound with a slight bump in the upper bass/lower midrange (to great effect I might add), all of the LS3/5a speakers I’ve heard are goosed in a similar manner. Some not so much, yet it’s always there if you listen for it.

The Vanguards don’t have this pronounced effect, delivering what is arguably a slightly more transparent midrange. I admit to being biased towards a warmer sound, mating the Vanguards to a tube amplifier is more my cup of than a budget solid-state amp. Where the LS3/5a’s combined with a tube amplifier can be too much of a good thing with certain pairings, the Vanguards are lovely. Of course, you must be the final judge.

A quick peek inside the Vanguard reveals high quality crossover components, and less of them. Where the BBC licensed speakers use 11 components, Dr. Nguyen’s design makes do with 6. Claimed sensitivity is 84.5dB/1-watt, but thanks in part to this reduced parts count, the Vanguard is incredibly easy to drive. 25 Watts per channel will get you rocking.

Running the gamut

You’ve probably seen massive amplifiers powering small speakers at hifi shows to deliver higher than expected performance. You might consider this “cheating,” yet it does reveal just how much a budget speaker can deliver. Taking this approach, listening began with the dCS Vivaldi ONE-Apex, Pass Labs XS Pre and a pair of Pass XA200.8 monoblocks, all connected with Cardas Clear cable.

I’d be lying if I didn’t say this was pretty awesome, albeit unrealistic. After trying several different amplification choices, the two I settled on for most of this review were both realistic matches. The $1,299 LSA VT-70 (EL-34 powered), and the ($4,100) T+A Caruso R (solid-state, all in one) delivered great performance, and both make great partners for these speakers. While the T+A Caruso R is three times the cost of the LSA amp, it does feature an integrated tuner, DAC, CD player, streamer and MM phono stage. Together with the Technics SL-1200G, we are awarding this combination one of our two system of the year picks for The Audiophile Apartment.

Investigating the vintage path, the Vanguards also work well with the vintage components we have on hand from Sansui, Marantz, and Nakamichi, though keep in mind these speakers resolve enough detail that you will detect a bit more “wooliness” with older gear.


Many audio enthusiasts love mating mini monitors to a small subwoofer to extend total system response. Most listening was done in an 11 x 13-foot room and a 12 x 18-foot room. As you might suspect, the larger room benefitted more from a bit of LF augmentation, though with careful setup, it worked in the small room as well. However, resist the urge to combine the Vanguards with a budget subwoofer. The detail that they do resolve in the lower register will be lost in the lack of transient speed that always comes along with a cheap subwoofer.

That being said, the SVS Micro ($899) and the REL Tzero MKIII ($499) both make an excellent match for these speakers, but that’s another movie. You do not need to have a subwoofer to enjoy these speakers.

In Perspective

In a day where some speaker manufacturers charge more to custom paint a speaker cabinet than Porsche charges to paint your car a unique color, no one at XSA is getting rich building these speakers. Even if these cabinets were made from MDF (and they wouldn’t sound nearly as good) $799 would be an incredible bargain. To keep it a fair fight, because these speakers are only sold factory direct, they should be compared to speakers costing twice as much – yet they still deliver superb performance.

As a reviewer, it’s easy to lose your way, trying to convince the audience that they need to spend more, more, more, and if you don’t, you can’t play. It’s also easy to lose sight that anything beyond a pair of wireless buds for your smart phone is a luxury on one level, because that’s all you really need to be a music lover. Investing more than that in your hifi system is still a luxury, no matter what level you are engaged.

Some of the most passionate audio enthusiasts I’ve encountered over the years have been those that put a $2,000 – $10,000 system together with extreme care, working hard to achieve the maximum value with every component.

Whether you are putting together your first major system, downsizing from a big system, or putting an additional system together in another part of your living space, the Vanguards are a great pair of speakers that are more than worth the price asked. Should you purchase a pair, I hope you enjoy them as much as I do – they are staying.


The Carver Black Magic 25

Sometimes less is more, especially when it comes to vacuum tubes. There’s always something special about a low-powered tube amp and a pair of fairly sensitive speakers. Bob Carver’s latest, the Black Magic 25 is a perfect example. Sporting a fairly compact chassis size and tube compliment (1-12AU7, 2-12AX7’s, and 4-EL34s) the Black Magic certainly made some great music here, paired with our Zu Dirty Weekends and the Heretic A-1614s.

Build quality is robust, yet sparse, and the amplifier is a cinch to use. There is a handy meter on the front panel that can be used as a tube tester, as well as for setting the output tube bias. Carver claims that their unique circuit means you don’t need matched output tubes, yet our experience with only one bias control for four tubes suggests otherwise.

The amp runs cool, and provides a sound not as romantic as a vintage Mcintosh, Marantz or Dynaco amp, yet still delivers plenty of tubey, midrange magic that you’d expect. And of course, with only three input tubes, you can roll em’ if you’ve got em’ to fine tune and experiment.

Thanks to careful design, this little jewel plays louder than you would expect a 25Wpc amp to play, even with less efficient speakers like a pair of Harbeths, or your favorite LS3/5a variation on the theme.

Definitely a good thing in a small package!

REL Raises The Bar

The new no.31 Reference Subwoofer is a substantial improvement.

If you aren’t paying close attention, you might easily mistake REL’s new no.31 subwoofer for one of their outgoing reference models. Upon close inspection, aside from the new super-coolio carbon fiber badge, the rear facets of the cabinet top are beveled – a further effort to refine the shape and eliminate resonance.

We often discuss break-in time in terms of days and hours, yet the difference between the no.31 and RELs past is immediate. The no.31 is faster, more nimble. If you only think of the low-frequency augmentation provided by a subwoofer as a single sonic shade, be prepared to have your paradigm reset.

Those familiar with the effect of adding one (or more) REL subwoofers to their system, will be equally impressed. John Hunter and his team have pushed the possibility of what a subwoofer can add to a high performance audio system further than ever.

More Power From LSA!

The New VT-150 rocks…

$2,499 Intro price: $1,999 (Black Friday – 3 days ONLY)

You know we had a great time with LSA’s VT-70, featuring EL-34 power. Jerold O’Brien even
bought the review sample. It’s a pretty incredible little amp for the size and definitely for the

However, 35-40 Watts per channel isn’t always enough for everyone. Bam, they just introduced
the latest VT-150 model, sporting four KT-88 tubes. Following the PrimaLuna and McIntosh
playbook, the tubes are “branded” with the LSA logo. Nice touch.

The newer (and heavier) amplifier now pushes out about 75 Watts per channel, and the bias
can be dialed up to work with the KT-150 tubes for close to 100 Watts per channel. Those of
you not familiar, keep in mind those last 20 Watts are gonna set you back about $600, (for a
set of KT150s) so if you HAVE to have it, that’s the cost of more juice. The rest of you will do
just fine with the KT88s.

Thanks to the careful attention paid to component choice and transformer construction, the
VT-150 is a class leader, just like the VT-70. Slightly less sweet, but more extended at both ends
of the frequency spectrum, as it is with all other amplifiers utilizing this tube.

We’ll have a full review shortly, but our initial impression is VERY favorable!
