Boulder 810 preamplifier and 850 monoblock amplifiers

This relatively affordable amp-preamp combo from the legendary ultra-high-end audio company is dead quiet both electrically and mechanically, and was “exhilarating to listen to on a number of levels.” Possessing the same level of fit and finish as their flagship line of products, this pair was more than happy to be split up and used with other brands but offered an unusually high level of synergy together.
