AHB2 - Lab Report - Amirm, Audio Science Review

by Benchmark Media Systems May 30, 2019

"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."
