"In this age of ultra-refinement in the production and playback of music, Benchmark Media shows that it is to be recognized as a paragon of musical integrity at an affordable price point."
"I suspect that especially younger ears, and the ears of those who spend much time with headphones, will appreciate the Benchmark sound. I appreciate them as I have experienced many less accurate systems, and I revel in high purity playback."
"The only listener who will need to consider carefully prior to commitment to Benchmark is the lover of warm, perceptually “softer” or “laid back” sound."
"Those who are seeking a highly revealing sound, perhaps considered “honest” or “truthful”, and invigorating, would find great satisfaction with these components."
- Doug Schroeder, dagogo.com
"The folks from Benchmark and Martin-Logan teamed up to do something just a little different, and entirely enchanting, in the Jackson Room!"
"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!"
- Greg Weaver, enjoythemusic.com
"If we had to categorize the sound of the DAC3 using three words, those words would be precision, precision and precision."
"Partnered with the AHB2 power amplifier, the system represents a significant powerhouse in a relatively small footprint."
"Dynamics were surprisingly tight, quick and responsive in a manner that would make most audiophiles take another look at the “pro” side ..."
"The AHB2 makes use of THX Corporation's Achromatic Audio Amplifier (AAA) technology, in which a low-power feed-forward amplifier drives a low-bias class-AB output section, the latter energized by a system of class-H power-supply rails that deliver power in response to demand—resulting in an extremely efficient amplifier capable of robust power output."
"In his listening tests, KR discovered "much more apparent low-level detail in already-familiar recordings"—a characteristic he credited to the Benchmark's evident noiselessness—and a tonal balance that "sounded more 'right' than any of [the other amps on hand].""
"In measuring the AHB2 and attempting to confirm its specified very high signal/noise ratio, JA observed nonlinearities in his testing equipment that "haven't affected the measured performance of other amplifiers I've tested, but they were detectable with the AHB2's very low intrinsic distortion and noise." His conclusion: "an extraordinary amplifier.""
"KR's last word: "bargain.""
"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."
"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."
- Peter Davey, Positive Feedback
"As with a Class A amplifier, I could detect the muscle of the AHB2 and hear it in the sheer weight of presentation in the lower octaves."
"The AHB2 can drive virtually any speaker load with significant power--especially in monaural mode--yet it never lacked finesse on delicate passages."
"It is a technologically advanced and remarkable amplifier ..."
- Ben Shyman, Home Theater Review
The AHB2 was one of only 11 finalists in Stereophile's "Amplification Component of the Year" category. The finalists included 6 power amplifiers, 2 preamplifiers, 2 integrated amplifiers, and 1 headphone amplifier. This elite selection of amplification products included power amplifiers ranging in price from $2,995 (Benchmark AHB2) to $52,000 a pair (Vandersteen M7-HPA).
At $52,000 the Vandersteen includes a chassis milled from a solid billet of aluminum, liquid cooling and a vibration dampening suspension. It is an impressive example of mechanical engineering and industrial design.
At $2,995, the Benchmark AHB2 delivers the quietest, cleanest power available at any price.
The AHB2 proves that top-quality audio can be affordable.
It's not the first time I've heard Error-Correction amplifiers, but those were prototypes that weren't working all too well. Classic feedback, TIM-free design was better, so I was afraid that AHB2 might be “wrong” somehow. It took a little bit of “leap-of-faith” to buy one, but I could not ignore the advice I was given about it, as it was given by people that are insiders in this Audio industry of ours. I'm happy to say that my thoughts of Error Correction approach being maybe wrong, could not be farthest from the truth.
What can I say ... maybe the shortest way to summarize it would be this: the AHB2 is the end of the journey for me. I have no desire for ever going back to typical multi-thousand Dollar High-End amplifiers.

"Benchmark Media Systems Pro-centric products tout exceptional specifications, and their AHB2 amplifier--developed in tandem with engineers from THX and using their patented HX Achromatic™ Audio Amplifier technology—uses some rather unusual patented designs to get to those remarkable spec numbers."
"These two partners in musical misbehavior sound great together and cost less--with Benchmark cables included—than my Pass XA 30.8 amp alone. To be sure, my reference Pass is a fantastic amplifier, but the AHB2 has its own charms that I found played to my own listening biases."
"Yep. Good stuff, those BM boys."

At the 141st AES conference we demonstrated two Benchmark AHB2 monoblock power amplifiers driving a pair of 4-Ohm PMC IB2S passive studio monitors (these monitor are also available in the PMC IB2SE hi-fi version).
In bridged mono, the AHB2 can deliver over 518 watts into each of these 4-Ohm speakers. This is a perfect match to PMC's 500 watt recommendation. The AHB2 easily provides the power, the output current, and the damping required by these low-impedance speakers.
"I am very impressed with the clarity and accuracy of these outstanding professional monitors. The Benchmark AHB2 and PMC IB2S are an absolutely killer combination!" - John Siau, VP, Benchmark Media Systems, Inc.
