AHB2 Review - Gary Galo, AudioXpress

AHB2 Review - Gary Galo, AudioXpress

"Our main cover article is an in-depth review of the Benchmark AHB2 Stereo Power Amplifier by Gary Galo. If you are interested in amplifiers, this review will clearly explain why you should listen to this one. Benchmark's new AHB2 stereo power amplifier uses feed-forward error-correction technology patented by THX that virtually eliminates crossover distortion. Designed in response to the needs of high-resolution audio sources, each channel of the AHB2 actually has two amplifiers - the main bi-polar Class-AB amplifier for driving the loudspeakers, and a low-power error-correction amplifier with ultra-low distortion levels. Gary spent some time with it and explains all the reasons why he was impressed. Very impressed."

"The AHB2 easily outperforms the DIY Hypex NC400 I had tested before which used to be the best amp I had tested."

"THD+N versus output level looks far cleaner than anything I have tested before."

"Intermodulation distortion versus power level shows the same story of clean power."

Signal to Noise Ratio:

(unweighted, 22.5 kHz BW)

  • Ch1: 130.286 dB

  • Ch2: 130.180 dB

Frequency Response:

  • -0.3 dB at 20 kHz

  • -3 dB down at 200 kHz!!

"Since this is not a switching amplifier, there is no filter there allowing the bandwidth to go to 200 kHz and beyond."

Stereo Power into 4 Ohms:

"We have 185 watts of power at incredibly low distortion of 0.00016%, besting the company specifications."

Bridged Mono Power into 4 Ohms:

"500 watts into 4 ohm! Stunning 0.00026% distortion at 500 watts!!"

"It goes without saying that the Benchmark AHB2 breaks new ground ... gets my strongest recommendation."

"The AHB2 power amps ... are fantastic."

"I use them as mono blocks due to my power hungry speakers."

"I hear clarity, precision and an openness in the treble that I haven't heard in my speakers before."

"The HPA4 line and headphone preamp and the power amps are made for each other..."

197 Rooms - Benchmark Room makes a "top 3" list

"The effortless and free-flowing nature of the Martin Logans paired up nicely with the transparent AHB2 amplifiers."

"The tonality and realism of the instruments were spectacular. An alto saxophone sounded as if it was in the room with me, and the pitch and timbre of both male and female vocals were absolutely spot-on. It was clear that nothing in this system was getting in the way of the music."

"Their room had a remarkable degree of transparency that made every listener feel closer to the music."
