"If ever there were a giant-killer of an amp, this is it."
"Benchmark Media Systems’ modest-looking little AHB2 power amp may be hi-fi’s biggest bargain. It is one of the -- if not the -- quietest, most resolving amps I've heard. Time and again, without ever having intended to, I wound up hours deep in listening to the fringes of my music collection, thanks to the AHB2’s reference-level transparency and obscene athleticism."
"The AHB2 was, almost without qualification, astonishingly good. Spotting sonic differences among the ocean of class-AB amps offered for less than $10,000 can be challenging because those differences can be so subtle. But with the Benchmark, it was immediately apparent that I was listening to something special. Only one other amp has come close to matching the AHB2’s utter lack of noise and grain. I recall putting my ear practically on my speaker’s tweeter to hear only the faintest white noise from the Devialet 120, and I had much the same experience with the AHB2. There was just nothing there. Reading this on your screen, it might be difficult to imagine so total an absence of grain or noise floor in the sound of your own system. But let me tell you, the effect was profound."
"The AHB2 was incredibly transparent. It just tore down the cloud of ambiguity that burdens the sounds of, well, just about everything else I've heard."
"Wanting to hear how the AHB2 would handle richer, denser music, I cued up the high-resolution version of “Get Lucky,” from Daft Punk’s Random Access Memories (24/88.2 FLAC, Columbia). My concern about this monster single sounding in any way threadbare was misplaced. Pharrell Williams’s velvety chorus was supple and substantive, while the foundational bass guitar and kick drum were as solid as I could hope to hear them. The higher the fidelity of recording I threw at the Benchmark, the more rewarding my listening experience became."
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."
