AHB2 - Driving Martin-Logan ESL 11A Electrostatic Speakers
DAC3, AHB2, ESL 11A - "Something a Little Different, and Highly Enchanting"
"The folks from Benchmark and Martin-Logan teamed up to do something just a little different, and entirely enchanting, in the Jackson Room!"
"Multi-channel bliss with the Martin-Logan ESLs driven by an all Benchmark system."
Benchmark and Martin-Logan System at Capital Audiofest, 2017
- 3 Benchmark DAC3 Converters
- 5 Benchmark AHB2 Power Amplifiers (Bridged Mono Mode)
- 5 Martin-Logan ESL 11A Electrostatic Speakers
- 2 Martin-Logan Balanced Force 210 Subs
"The resultant sound was extremely clean and fast, surprisingly dynamic, and the space, as you'd expect with good multi-channel, was get-up-and-walk-around through. Well done!"

Martin Logan ESL 11A
"I'm not clear what sources were used, but by using three DAC2 HGC DACs ($2,195 ea.), to feed five Benchmark AHB2 amps (which I reviewed back in November of 2015), each configured as a monoblock ($2,995 ea.), they drove three Martin-Logan Impression ESL 11A's ($9,995/pr.) across the front, and a pair of ESL X's ($4,000/pr.) for rears. Supported by a pair of Martin-Logan Balanced Force 210 subs, ($2,995 ea.) everything was connected with Benchmark cables."
"The resultant sound was extremely clean and fast, surprisingly dynamic, and the space, as you'd expect with good multi-channel, was get-up-and-walk-around through. Well done!"

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."
