"As a headphone amp: I sampled the DAC2 with both Grado 325i's and Focal Spirit One cans. The DAC2 was more than capable of driving either of these and made them each sound their best."
"The Benchmark DAC2 HGC does so many things – I didn't even get to all of them – and does them so well, it's easy to recommend. Got an old amp and you need a preamp to make a system out of it? DAC2. Want a first class headphone amp? DAC2. Computer audio? Of course. It's not the least expensive option for any one of those but it might well be the most affordable when you compare to other solutions that are as versatile – if you can find any. The sound is sweet, engaging, and long on textural detail without fatigue. You should definitely check this DAC out."
LA4 - Receives Stereophile's Highest "Class A" Rating for Preamplifiers
"Benchmark's usual approach to design is to out-spec the competition, and so it is here. Like other Benchmark equipment he has tested, the affordable LA4 challenged the resolution of John Atkinson's test instruments, with'superb'channel separation,'extremely low noise, and virtually no power-supply-related spuriae.'"
"Benchmark's LA4 is the widest-bandwidth, widest-dynamic-range, lowest-noise, lowest-distortion preamplifier I have encountered."- John Atkinson
"In his listening room, Kalman Rubinson compared the LA4 to a cable—and couldn't hear any difference. He concludes,'the LA4 is probably the most transparent and revealing audio component I've ever used. It does not seem to leave any fingerprints on the sound.'"
"The DAC3 B is a stripped- down, lower-priced version of the DAC3 HGC, which omits the headphone amplifier, balanced and unbalanced analog inputs, volume, mute, and polarity controls."- Stereophile
"The DAC3 was all about depths, in several respects...I heard deeper into the music."
"All I can say is Wow!"
- John Atkinson
"In a Follow-Up, JCA wrote of using the Benchmark processor with the same company's AHB2 power amp—a combination of high source output voltage and modest amplifier gain that he describes as 'optimal for minimizing noise and distortion' —and reported hearing 'richer and more interesting' reproduction of very subtle details."
