AHB2 & Marting Logan ESL 11A - Axpona 2019 - The Audio Beatnik
DAC3 B, LA4, AHB2 - Driving Martin Logan ESL 11A Electrostatic Speakers
197 Rooms - Benchmark Room Makes the Audio Beatnik "Top 3"
"The 10th annual AXPONA was the largest yet with an expansive array of speakers, amplifiers and turntables on display across a staggering 197 listening rooms."
"Certain rooms featured systems most enthusiasts could probably afford at some point in their lives, and other rooms catered to the small well-heeled handful who are willing to spend extravagantly to obtain the best possible sound. That’s why I divided my top rooms into two categories: the best three “reality” rooms where the systems were more reasonably priced and the best three “dream” rooms where cost was no object."
Benchmark and Martin Logan - "Reality Room #2"
"Benchmark teamed up with Martin Logan to drive a pair of their Impression ESL 11A electrostatic speakers with their AHB2 power amplifiers in a bridged-monoblock configuration. The source was an Aurender A10 streamer fed through their own DAC3 B and an LA4 preamp."
DAC3 B - Featuring High-Headroom D/A Conversion
LA4 - Featuring 256-Step, Relay-Controlled Volume
AHB2 - Featuring THX AAA Feed-Forward Error Correction
"The overall sonic signature of this room had a remarkable sense of ease and purity. Minute details such as a breathy initial saxophone note or a solo vocalist parting her lips and taking a breath before singing were easily discernible. At the same time, they presented all of the musical energy and rhythm contained within the source material."
"The effortless and free-flowing nature of the Martin Logans paired up nicely with the transparent AHB2 amplifiers."
"The tonality and realism of the instruments were spectacular. An alto saxophone sounded as if it was in the room with me, and the pitch and timbre of both male and female vocals were absolutely spot-on. It was clear that nothing in this system was getting in the way of the music."
"Their room had a remarkable degree of transparency that made every listener feel closer to the music."

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."
