"The AHB2 is being recognized as a Recommended Reference Component -- it’s an incredibly good amplifier that can take full advantage of the high-resolution music sources that audiophiles have access to today."

“I measured less distortion and noise in the AHB2 than in any other of the many power amps I’ve measured over the years.”
AHB2 -"Less distortion and noise than any other power amp I’ve measured over the years"
"All amplifier measurements are performed independently by BHK Labs."
"The AHB2 is Benchmark’s attempt to produce a very-low-distortion, low-noise power amplifier using THX’s AAA Technology, which linearizes the amp’s class-AB output stage without using large amounts of overall negative feedback. I must say that they’ve succeeded; I measured less distortion and noise in the AHB2 than in any other of the many power amps I’ve measured over the years."
"High-frequency THD+N is admirably low, and in stereo and mono modes, the AHB2’s level of distortion throughout most of the power range is amazingly low."
"... the signal harmonics -- consisting of the third and fifth harmonics in stereo mode -- are extremely low in amplitude."
AHB2 -"Lowest Noise and Distortion Power Amp I Have Measured"
"The new Benchmark AHB2 is the result of considerable research and patents on its resultant circuitry. The intent was to make it an ultra low distortion design. I would have to say they succeeded as it is the lowest noise and distortion power amp I have measured and I have measured a LOT of power amps in my career."
"The S/N ratio was about 131.6 dB. Pretty impressive, and this is the lowest output noise level I have seen in any power amplifier I have measured! (Editor's note: Benchmark measured 3 dB better when input was terminated with 60 Ohm impedance input.)"
"When connected in bridge mode, power was close to 400W into an 8 ohm load."
ADC16 -"Numbers That We Come to Expect From This Engineering-Driven Company"
"The noise floor is an impressive approximate -120 dBFS but the distortion takes quite a reduction of input level to get there – approaching 0.0001%!"
"All in all, the basic measurement parameters of the Benchmark ADC16 are in or near the top of A/D converter performance standards — numbers that we come to expect from this engineering-driven electronics company."
