AHB2 Bench Test - Bascom H. King, Everything Audio Network
"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."
"Overall HF bandwidth is quite high with a 3 dB down point of 200 kHz or more."
"AC line draw at idle was 20W with a power factor of 0.46 and 0.37A."
"Input impedance was an easy to drive 47K at 1 kHz."

Why Did You Buy Benchmark Gear?
"I'm asking because clearly Benchmark is a highly regarded company here, and plenty of ASR members own Benchmark amplification/DACs. We know they are top of the heap in terms of measured performance, outdoing plenty of the competition in terms of typical distortion measurements."

AXPONA Review - Secrets of Home Theater and High Fidelity
"The afternoon before the start of the show I ran into John Siau of Benchmark Media Systems. He says to me quietly, “make sure you stop in our room, we have a surprise!” With curiosity suitably piqued, Co-Editor Jim Clements and I paid a visit ..."
"The results were pretty astonishing. A stable, enveloping stereo image that was devoid of any distortion whatsoever."

AXPONA Show Report - Stereophile Magazine
"Sound was extremely well-integrated and controlled, and the bass memorable."
"The Note received signal through the introductory version of the company's Liquid Cables. Each cable contains 27,000 wires. The company's introductory Elephant memory player joined Benchmark Media's AHB2 power amps, DAC3 B D/A processor, and interconnects."
"With the aid of a forthcoming DEQX HDP4 processor that's due in the fall, the system sounded super on a 16/44.1 file of the famed rendition of Copland's Fanfare for the Common Man, recorded by Eiji Oue and the Minnesota Orchestra for Reference Recordings."
