DAC2 & AHB2 Review - Dimitris Stamatakos, AVMENTOR.net
AHB2 - "What the Future of Power Amplifiers Can Be"
DAC2 & AHB2 - "The best preamplifier/power amplifier ... in this price range"
"For the listening test, DAC2 HGC and AHB2 replaced our regular reference preamplifier and power amplifier (Melos Plus Series Line and Parasound HCA3500) to drive the ATC SCM50PSL loudspeakers with the Teac P70/D70 CD transport/DAC as a source."
"Replacing the reference amplifiers with the Benchmark devices introduced some interesting and significant changes in the system."
The first impressions include a more clear, dimensionally stable and well-defined soundstage, a better performance on detail and a better feeling of macrodynamics of the listening material. The end result was effortless and uncompressed, with very good speed characteristics and a sense of balance."
"Low frequencies appeared comfortable, well extended and balanced while, in comparison, the reference amplifiers sounded somewhat exaggerated and larger-than-life in this part of the audio spectrum. In contrast, the Benchmark system seemed tighter and with a more strict character without depriving the listener of any details contained in the recording."
"Rhythm section parts reproduced effortlessly, with great speed, and a sense of fullness, without ever becoming excessive."
"Stereo imaging is clear, well defined in space, with very good resolution and a sense of transparency and good depth. Voices feature very good articulation and detail and the overall presence is very realistic, both in small orchestras and solo voices and in larger scale projects and choirs. It is obvious that the design of the amplifiers is done with some "good monitoring" values in mind, like tonal accuracy and a coherent soundstage."
"Towards the high-frequency part of the audio spectrum, the DAC2 HGC/AHB2 combination sounded quite pleasant -but without being intentionally soft or euphonic- and offered a very well balanced feeling of brightness and wide bandwidth. From the listener's point of view, the result is a restful character, without any trace of harshness."
"The overall impression is that the system is able to pass into the listening room both the harmonic richness and the tonal balance of the recording."
"The Benchmark pair offered near-flawless attack/release times and sounded full and impressively present even in small details, a behavior that reinforces the sense of precision and carries the listener a step closer to the live performance."
"Based on a very interesting set of ideas, with a long history but few examples of a practical application, the Benchmark AHB2 could serve as a convincing example of what the future of power amplifiers can be. Combine it with a renowned D/A Converter like the DAC2 HGC, and what you have is a top quality system from which only the loudspeakers are missing!"
"While the DAC2 HGC is a, pretty much, well-known device, the AHB2 proved to be a very pleasant surprise, indeed."
"Benchmark dared to engage their power amplifier project from a different angle, discarding the standard approach ... and certainly succeeded. The theoretical advantages of their choices are both evident in the laboratory and heard during the listening sessions, thus justifying the whole approach."
"Overall, the DAC2 HGC/AHB2 pair is the best preamplifier/power amplifier we had the opportunity to listen to in recent years in this price range."

DAC3 - Award Nominee - Best Digital Audiophile Product of 2024 (Cost No Object)
2024 Nominees
- Benchmark Media DAC3 B DAC, $1895
- Bricasti M3 DAC, $6000
- Bricasti M19 CD-SACD Player, $10,000
- T+A DAC 200, $7620
- Weiss Engineering Helios DAC, $21,995
"There was some debate about whether anybody can hear the differences above a good Chi-Fi DAC like the Topping D90. Unless you are missing most of your high-frequency hearing, you can hear where a high-end DAC makes a difference."
The Bricasti M3 is a great example of that performance in a $6,000 DAC."
"The Benchmark DAC3 B is an audiophile DAC, with pro audio roots, that punches way above its weight."
LA4 Review - Mike Prager, FutureAudiophile.com
"Benchmark Media Systems made its reputation in both pro audio and audiophile circles by designing gear with extraordinarily low noise and distortion, and selling it at reasonable prices."
"What Makes the Benchmark LA4 Preamp So Special?"
"A high-quality volume control is much of what makes a superior preamp shine, and the Benchmark’s volume control is outstanding. The Benchmark LA4 uses a bank of precision resistors switched by gold-contact relays to set volume in 256 steps of 0.5 decibels each."
"If accurate reproduction is your wish, you won’t find a preamp with meaningfully better objective performance than the Benchmark LA4, especially one made in the United States at anything near the LA4’s price."
"Very few preamps at any price reach the LA4’s level of objective performance."
"On the subjective end of things, the Benchmark LA4 preamp puts the lie to the old audiophile myth that neutrality means clinical, cold, or sterile sound. Instead, here neutrality means musical, involving sound, with precise, stable imaging, a sense of space (if one is on the recording), and exceptionally truthful timbres."

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."
