I heard it pushing Martin Logan panels hard. Not impressed. The room was probably a factor but I get better sound at home with ICEpower driving Acoustats.
Not the last time that dopes think demo means LOUD. The amp seemed to square it off.
Benchmark AHB2 or Class D (GaN FET)
The Benchmark AHB2 seems to be a different twist on linear Class AB amplifier design. This amp uses a different approach to distortion cancellation that gets around some of the problems of using large amounts of negative feedback. It uses a THX patented technology (under license) called AAA. This amp has been around for several years. It gets rave reviews, so I am surprised that the technology is not in more widespread use.
I am interested in why this approach is not more widely used.
Also, how would this amplifier compare to the newest Class D technology, which uses GaN FETs and much higher switching frequencies. (GaN Class D amplifiers which are price-competitive with the AHB2 are the LSA Voyager and Peachtree).
At a higher price point would be Atma-Sphere Class D monoblocks and the AGD Tempo.
I would appreciate hearing the forum members' opinions on the AHB2 technology vs the latest Class D amps.
Thanks,
