"THX has patented a novel amplifier design, THX AAA Technology(TM) and Benchmark Media Systems has turned it into a new power amplifier – AHB2. The design is called Achromatic Audio Amplifier. Achromatic may mean colorless or neutral or without modulation. The AHB2 is an attack on current amplifier design. It’s basically an AB amp with a class H power rail arrangement."
"A low power Class A correction amplifier ... runs in parallel with the regular AB amplifier ... and corrects ... non-linearity in the transition stage."
"The AHB2 is a class AB amp – but could easily be mistaken for a class D with its very compact dimensions. The small size is made possible by the compact switching power supply."
"The AHB2 has a resonant zero-voltage switching power supply. The switching is carried out at frequencies well above the audio band to reduce any audible artifacts from the power supply. Switching power supplies are much more efficient, and smaller, than linear transformer based supplies."
"The AHB2 power supply is regulated and very efficient in combination with the H Class rails. Benchmark claims that there is no sagging in internal voltage during high loads or when line voltage dips."
"The amplifier has a spectacular frequency response of 0.4 Hz to 200 kHz. This means that the AHB2 will amplify the high frequencies present on high res digital files."
"So is there a sound signature to the AHB2? Since THX calls it Achromatic we can assume that they were not aiming for a warm and sweet tubey sound – and this is not what it delivers. The sound is indeed neutral and exact without being sterile or clinical. Colorless? Not really. The amp will send through the sound palette of the source component and disc/file without stripping any color away."
"The Benchmark AHB2 is a solid foundation for an audio system. It is very quiet with extremely low distortion."
"The AHB2 is so good it will immediately expose weaknesses in your system. It requires a very good pre-amp ... which should output a balanced signal."
"Medals to everyone and a rebel princess to the AAA Technology inventor!"

Benchmark's Rory Rall shows a storm trooper the AHB2 power amplifier at the NAMM 2016 Show, and explains the new THX AAA Technology. Rory waved his hand and was heard to say: "These are the amplifiers that you are looking for."
"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."
- Geoffrey Vanhouwaert, Alpha-Audio
"The Benchmark AHB2 is a very fine sounding, easy to live with, zero-maintenance power amplifier that has enough power for most systems. If more power is needed, two amplifiers configured for mono can provide it. The decision to purchase the review sample and make the Benchmark AHB2 a new, long term reference took over a month of listening and comparisons."
"The outstanding musicality of the Benchmark AHB2 takes some time to convince the listener of its wholly musical presentation. This subtle excellence assures long term satisfaction."
-10 Audio, Perfect 10 Award
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!
