PS Audio NuWave DAC Stand and Deliver

By Rob Johnson

Working as a DJ for hire in the eighties, I was exposed to more than my share of New Wave songs, upturned collars, pastel colors, and hair gel. During those years the early CDs started taking hold. With them came forth the digital music revolution for the consumer, challenging the dominance of beloved records and cassettes. While analog will forever have a place in the hearts of audiophiles, the raw convenience of digitally stored files enables and maintains a solid grip. Digital-Analog Converters (DACs) today bring forth a great deal of musical pleasure from the latest high resolution digital files and also breathe new life into older standard CD-quality 16bit/44.1kHz material.

With all my fond memories of the New Wave era, the NuWave moniker on PS Audio’s latest budget DAC has a lot to live up to. Could it provide the same high level of musical enjoyment I associate with my past?

The Ghost in You

The NuWave carries high quality internals, though it serves as the entry level DAC in PS Audio’s product line. Its big brother, the $3,995 PerfectWave, has handed down one of its strengths – its low-jitter clocking circuitry – to its smaller sibling. The benefit of this capability is pulling from the source the best possible digital stream to be processed. From there it is sent to the analog section which is fueled by a very substantial power supply; then it’s translated into music.

Close to Me

On close inspection, the NuWave is a petite 14” long x 8” wide by 2.5” high. It weighs in at around 12 pounds. Once placed on a shelf the front profile is quite modest. The metal case of the test unit is coated in a matte black finish. Silver is also available from PS Audio. The front panel has aesthetically pleasing curved edges wrapping around to the sides.

Buttons on the front, and the PS Audio logo on the left side, glow blue. With some equipment I’ve experienced, LEDs have the potential to scorch a retina, but not with the NuWave. In this case, the overall appearance is both pleasant and subtle.

The package does not include a remote, which makes sense given the basic in-and-out philosophy of the NuWave’s build. There’s not a lot to adjust or control after a source is selected and a standard or up-sampled signal chosen. One additional LED indicator notes whether the PS Audio has a solid lock on the signal.

I was surprised that no USB cable comes with the NuWave. You’ll definitely want to have that on hand for setup. I found the Cardas Clear USB a good match. PS Audio does include a very basic power cord, but it’s likely one you will want to upgrade later to get the most from the unit.

One Thing Leads to Another

Physically connecting the NuWave to the rest of the audio system proves straightforward. The PS Audio offers three inputs for digital sources including USB, S/PDIF coax and TOSLINK. The USB connection provides the greatest flexibility for high resolution files and will serve most users as the best option for computer-based music. While there is not an AES/EBU digital input on this DAC, the RCA coax input serves well as a secondary input source from CD players and other devices with a stereo digital output.

Despite the small size of the unit, this DAC has both balanced XLR and RCA outputs giving it helpful flexibility in an audio system.

With all cables connected, it’s a simple matter to choose the input source from the front panel selector button. If only one source is connected, the NuWave defaults to it. If multiple sources are connected to the DAC and one is playing, NuWave’s autoscan feature will pick the input receiving a signal.

Once that’s done, the user has another toggle to select one of two modes. “Native” mode creates a straight pipe from the source so a 16 bit/44.1kHz signal remains exactly that.  Another option is 24bit/192Khz up-sample mode. PS Audio recommends that users try both and decide what sounds best to them. Most of my listening took place on the “native” setting.

Work for Love

Once physically connected to sources, the final step is configuring a bit of software. PS Audio claims the NuWave acts in a plug-and-play fashion with a Mac computer, but a bit more human intervention is required for Windows-based systems. First, a driver must be downloaded from PS Audio’s website and saved to the computer. Once that driver is installed, a quick visit to the Windows 7 control panel’s “Sound” settings offers the PS Audio DAC as an output option. A right-click of the mouse gives a user the option to make the NuWave the default recipient of the audio signal.

Once complete, JRiver needs a small adjustment too. Clicking on the Player menu, and selecting “Playback Options,” a window opens which allows the user to make a few more minor changes. The “Playback Device” pull-down menu allows a user to select the NuWave as the default for music output.  On the same window, I selected a larger buffer size than the default setting to encourage and maintain the best streaming quality. Accepting these changes and closing the configuration windows, the only remaining step is selecting what music to enjoy.

In total, the configuration process took no more than five minutes, with most of that time consisting of driver download and installation. PS Audio does a nice job here to make the setup process streamlined for the NuWave DAC owner.

PS Audio suggests leaving the DAC powered on all the time so that it maintains optimal readiness for the best sound.

We Got the Beat

Testing begins with CD-quality source files. In the spirit of this review’s theme, it seems only fair to begin with Blondie’s “Heart of Glass” which many consider the first true New Wave song. Given the age of the recording and the CD’s limitations of a 16bit/44.1kHz signal, the right-to-left soundstage exceeds my expectations by extending well beyond the speaker limits. Perceived front-to-back layering is reasonable; however, it’s not the NuWave’s strength. Debbie Harry’s voice is recessed into the mix and when blended with the guitars and drums the result remains largely two-dimensional. This characteristic seems consistent throughout my Redbook CD test tracks.

Rock This Town

Stray Cats frontman Brian Setzer and his Orchestra provide a good test for the sonic portrayal of guitars, drums, and horns. His remake of “Rock This Town” offers significantly more polished recording quality than the original, though still limited to CD-quality. The NuWave captures all the energy and excitement of the performance.

The NuWave’s decoding process leaves the music enjoyable and fatigue-free. However this characteristic exists at the expense of some detail. In comparison with other, more expensive DACs on hand, the woodiness in saxophones diminishes. Bass, while quite deep, is not as tight. Similarly, the complex sounds of cymbals are truncated to a significant degree in comparison with the impact, ring and decay I’m used to hearing. Vocals are a bit hot in the mix. But at the NuWave’s $995 price tag, these are relatively minor quibbles considering what you do get. Especially from a price-performance perspective the PS Audio does a mighty good job and has the finesse to hold a listener’s attention through hours of listening.

Dancing With Myself

As the saying goes, “garbage in, garbage out,” so playback shifted to test higher resolution material. Though the NuWave there’s a huge sonic improvement in virtually every attribute.

For example, Stevie Ray Vaughan’s “Texas Flood” on 192kHz throws an impressively huge soundstage, both wide and tall. Vocals remain front and center where they should be, while drums step to the rear. The richness of the guitar on “Dirty Pool” reveals the level of emotion entrapped in the recording.

Similarly, Bob Marley’s “Is This Love” in 192kHz emerges with deep, plucky bass. Well-rendered, sonically convincing drum and tambourine pour forth. Background vocals complement and showcase the emotional undertones in Marley’s voice. This is especially evident during “Redemption Song.” While vocals remain a bit forward, individual strums of the guitar are almost tangible.

NuWave’s rendering of Norah Jones’s “I’ve Got to See You Again” layers vocals, piano, strings and percussion adeptly blended together in a cohesive and compelling sonic experience.

For those who have a lot of high resolution digital content, the NuWave will surprise you with its capability. If you don’t have high resolution content yet, you owe it to yourself to try it!

Make a Circuit With Me

After spending time with several DACs over the last couple months – the Chord Chordette Qute ($1,800), AUARALiC Vega ($3,500) and Light Harmonic DaVinci ($30,000) – some interesting comparisons emerge. Although a native 44.1kHz signal may not be a stellar source, each of these DACs takes what bits it’s given and outputs highly enjoyable, refined sound. At a cost multiple times more than the NuWave, a user should expect more from them.

When listening to high resolution content, the gap does shrink a bit and the NuWave showcases what it’s capable of resolving. It’s a big step up from CD-quality experience. The NuWave won’t unseat the other DACs, but it leaves a listener with a very satisfying musical experience for a small fraction of the price.

In essence, more money buys a user additional capabilities like DSD decoding, variable output, custom filters, and/or a remote. It also enables more natural sounding, three dimensional and nuanced portrayal of the music. In the case of the DaVinvi, opulently so, but at 30 times the price.

Take Me, I’m Yours

Caveats considered, the PS Audio offers a lot of value and does a very good job providing a no-fuss setup and usage experience. It offers all the basic functionality most users need a DAC to do, and the sound is mighty good for a component under a thousand dollars.

The Smiths made famous the New Wave classic song, “How Soon is Now?” How apropos for this review. For those seeking a high quality DAC under $1k, especially those who want to delve further into high resolution digital content, give the PS Audio NuWave DAC a try and you might find it in your home system sooner than you think.
