AHB2 Review - Barry Rudolph, Mix
AHB2 - "Unfaltering and Thrilling Performance"
"There is only one word for the AHB2: impressive"
"The AHB2 and the ML10Bs came through with unfaltering and thrilling performance every time."
"Immediately I heard that the AHB2 reproduced the recordings ambient space captured (or added artificially) as open and wide with reverb tails hearable down to the recording's noise floor. I could hear all of the reverb not more reverb--low level detail was more hearable much like wearing headphones vs. listening on speakers in a room."
"There was a pristine and smooth quality to the high and middle frequencies heard on the Tannoys. By comparison, another well-known power amp sounded "trashy" and harsh in the upper midrange."
"With the AHB2 there was an overall vibrancy and transparency not a hyped, bright sound. The transients--the spikey attack portion of snare hits, cymbal crashes and kicks are crystal clear if they are that way in the recording. Deep bass notes and loud kick drums are effortlessly reproduced without power amp compression as I sometimes hear on powered monitors--if there was any distortion it was the woofers themselves over-extending!"
"For listening to HRA directly at my studio, I bypassed my monitor controller completely and used Benchmark Media's DAC2 L digital-to-audio converter directly connected to the AHB2 ... For this test I borrowed a pair of Manley Tannoy ML10B monitors. If you like loud and room filling spectacular sound for classical pieces, you'll not be disappointed. The AHB2 and the ML10Bs came through with unfaltering and thrilling performance every time."
"As compared to my powered monitors, working on mixes in Pro Tools HD 11 through this system sounds more real, detailed and clear. In addition, this is a dead quiet--noiseless system. With no music playing, I could crank the DAC2 L's volume control wide-open and hear nothing--even with my ear right on the speaker cone!"
"There is only one word for the new Benchmark Media Systems AHB2 power amplifier: impressive. I highly recommend 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."
