AHB2 Review - Peter Davey, Positive Feedback
AHB2 - "It's phenomenal! Gobs of power, detail, finesse and control."
"Benchmark has been around for a long time. In fact, they are one of the early Audiophile pioneers of USB DACs ... I had always thought of them as more of a digital conversion company, and not an amplifier company—until the AHB2 came about."
"A PF colleague of mine (Steven Lefkowicz) said... Dude, you HAVE to try the Benchmark in your system (which at the time was going through a gamut of speaker changes as part of a myriad of reviews being done for PF) to which I replied, wow, they have an amp?"
"I was immediately taken aback with the level of detail given to this unit. Just one glance at the back plate will tell you that this is a well-engineered piece of equipment. Fully Balanced = Check. Speakon Outputs = Check. Bridging Support = Check. Input Sensitivity Adjustment = Check. 12v Trigger support = Check."
"The front panel is rather minimalist; a few LEDs to indicate the health of the amp and a power button. There is even a way to program the amp to turn on if it senses power so one can integrate it into a secondary power system if you wanted to (which then turns the power button into a mute circuit). Or, just leave it on all of the time. Even at LOUD levels, it does not get hot."
"I'm currently running it at a 4 Ohm stereo load, and the 190 Watts is going a long way! To be honest I haven't heard the amp clip yet, and I listen to music at cathartic levels sometimes (sorry, neighbors!). I believe these measurements to be on the conservative side."
"So, how does it sound, after all of that? Well, this thing is no slouch. It's phenomenal! Gobs of power, detail, finesse and control. I have thrown so much music at this tiny little amp, that I just can't seem to beat it to submission. It just takes it in and gives it right back. The damping factor is really at play here."
"For the price, you just can't beat it. If you have been looking for an all-in-one chassis stereo Class A/B amplifier that is reliable, energy efficient, and one of the best designs on the market, this is the ticket (it even comes in Black!). Most other offerings are at LEAST twice as expensive, and I can speak from experience that they don't sound half as good as this one. If I had the means, I'd keep this one as a perfect Swiss-army knife and never let it go. Hell, if you're feeling insecure about power, you can get two of them for cheaper than most Class A/B monoblocks out there, and have twice the power. Think no more, do it!"

AHB2 Review - Mike Prager, Future Audiophile
"For years, the audio world acknowledged one main contender (at least at sub-five-figure pricing) for the quietest, cleanest, most neutral power amplifier around. That was the Benchmark AHB2, whose specifications are still, for all practical purposes, unsurpassed, even by today’s excellent Class-D amps."
"10 years after its release, the Benchmark Media Systems AHB2 stereo power amp is still a standard-bearer in clean, neutral sound in the audiophile world."
"I greatly enjoyed having a pair of AHB2s in my system – their purity, neutrality, and seemingly unlimited power provided a clear window on the music and a lot of joy."
"I especially appreciated the AHB2’s smooth, well-integrated treble, free of splashiness or grain, and its natural reproduction of the human voice."

AHB2 Review - Constantine Soo, Dagogo
"The AHB2 bridgeable stereo amplifier ... was the topic of a recent discussion between American electrostatic panel speaker manufacturer Sound Lab’s president, Dr. Roger West, and me."
"In our discussion, he related his highly positive experience in driving even his largest, $55k Majestic 945 panels with the $7,000 pair of Benchmark Media AHB2 monoblocks, along with the $3,050 LA4 Preamplifier and factory XLR cables."
"Dr. West described the AHB2 as a class AB design using “feed-forward distortion reduction [thus removing] any possibility of pushing the margin of safety of a standard feedback loop, used in most amplifiers, into an unstable oscillatory mode.”"
"He further shared with me that “this is of most concern on powerful musical transients. The distortion of the amplifier in the balanced mode is astonishingly low even at just below the clipping level of 380 watts.”"
"The prospect of the AHB2’s specified distortion level of 0.00015% or lower when at full volume is comical at first glance, but upon actual audition the impact of the achievement is very audible from medium-high listening levels and upward."
"It was unlike any other sub-$20,000 amplifier I have auditioned."
"My audition of the Benchmark Media AHB2 amplifiers underscores the reason Dr. West is so taken by it, and confirms the design is best described as a watershed moment in the high-end audio industry."

DAC3 Review - Jerry Del Colliano
"Benchmark is a stalwart brand in pro audio, but has carved out a very respectable niche in the audiophile world with their diminutive but powerful components."
"The audiophile world sometimes looks to the professional audio world for enlightenment, especially on the digital side of things, and Benchmark Media is one of the companies that we put high on a pedestal."
"They are hardcore digital engineers freezing their asses off in upstate New York as they come up with some pretty innovative ways to get your varied digital sources sounding as much like the master tape as possible. Thank you for your service, gentlemen."
"If you really want to hear what your music sounds like in today’s streaming-driven world, this might just be the DAC that you need to test out."
