AHB2 Review - Mono Mode - Geoffrey Vanhouwaert, Alpha-Audio

by Benchmark Media Systems May 18, 2021 2 min read

"Benchmark Media Systems Inc from Syracuse, New-York is an American company and has been one of the top pro-audio manufacturers for thirty years. In recent years they have also ventured into the consumer market with considerable success."

"In collaboration with THX came the AHB2 power amplifier and not much later they developed a suitable headphone amplifier and preamplifier, the HPA4 and LA4 respectively."

"The HPA4 and AHB2 have been a fixture in our reference set for several years now."

Testing an AHB2 pair in Monoblock Mode

"In stereo mode we get a nice 100 watts (8 ohms class A/B) but in mono that goes to an impressive 380 watts!"

"We set the small switch on the back of the AHB2s to mono and connect each speaker to an AHB2."


"Is it worth buying a second AHB2?"

"We say a resounding yes."

"The extra power (380 watts!) not only gives you more control over your speakers, but so much more."

"The playback in mono is 'off the charts'."


"There's no going back really. You have been warned!"

System Review - DAC3, HPA4, AHB2 - Geoffrey Vanhouwaert, Alpha-Audio

by Benchmark Media Systems April 08, 2020 2 min read

"There are many things that come into play when putting together a hi-fi system, one of which is synergy."

"After the arrival of the Benchmark Media Systems AHB2, I immediately thought of the matching HPA4 that colleagues Jaap and Yung were very pleased with."

"The key question, of course, was whether the HPA4 would really provide an audible improvement."

"Well you bet! The synergy between preamp and power amplifier is nothing short of magical, not to mention the DAC3 B that I got from importer Helios for the occasion."

"Not only a few curtains disappear, the whole window is gone."

Alpha-Audio.net tested 10 DACs side-by-side. Only one received the "Alpha-Audio Approved" award. That DAC was the Benchmark DAC3.

"Are you looking for the best DAC (d/a converter) in the price range from 1500 euro to 2500 euro? That’s great! Because we’ve put ten beauties side by side. And we tested it live on camera for you."

"It was incredibly instructive to put so many converters side by side. We clearly hear differences - and the viewers could as well."

"One of the models we all agreed on is the benchmark DAC3. This is a delicious musical product. Virtually no coloring, nice stereo image and plenty of inputs."

DAC3 - Alpha-Audio Approved!
