VTV D300 Digital amp

Then what about the Class G used by Benchmark? 

Where is E & F I want to hear them. I know I am being a smart ass. 

This is not the first digital amplifier as the Technics SUG700R2 and the Flagship SUR1000 are both DIGITAL not CLASS D. 

The D in class D does not stand for digital. It's D only because it came after 3 previous classes, A, B and C

Do a search of my posts and website.....your will find the history....Tact in the 90s, with Lyngdorf using the same? code till now......then Technics.....and also the Exogal Comet Powerdac.

However, these boards from Elegant Audio Solutions are the first ever released that any manufacturer can use to make amps, integrated amps and powered speakers with......and, of course, the code was written by someone else than wrote the above......and it uses GaN transistors. Only the $10K Technics amp uses GaN fets. The $2.7K Technics uses mosfets on the output stage. Lyngdorf and Exogal also use mosfets.

Bi-amping with two of these amps with the Minidsp flex is so way cool. And you also use the flex to room correct and equalize. The benefits of not having a normal DAC, preamp, normal amp, analog cables and having zero passive xover parts plus room correction and equalization is completely over the top. Never before has this been done and you can do it right now. For instance, buy four 12 great inch woofers and mount 2 of them on an open baffle for each channel......put a serious tweeter above it......including the $150 Dayton large dipole AMTPRO-4 and wire the drivers directly to the amps....cross over at 1K and equalize and....OM frickin God.....you will be blown away......transparency like an electrostat without all that junk in the signal path. Of course, you can bi-amp any existing 2 way speaker by removing the passive crossover....and you can make a two way box speaker real easy too. The possibilities for mind blowing sound without spending very much are unlimited.

The Benchmark AHB2 amps letters A, H, and B allude to the unique topology of the amplifier’s output stage. The AHB2 combines class-AB, and class-H topologies using a feed-forward error correction system.

Come on guys and gals reading this thread you all have some interest otherwise you would not be reading it, let alone posting on it.

My research led me to this quote in the Enjoy the Music review.....that I thought I remembered correctly.....indeed, this old guy can still remember....he he:

"The AHB2 (named in tribute to Allen H. Burdick, who founded Benchmark Media Systems in 1983)"

@ricevs You are correct and so am I, a Kumbaya moment!

A.H.B.

The letters A, H, and B allude to the unique topology of the amplifier’s output stage. The AHB2 combines class-AB, and class-H topologies using a feed-forward error correction system.

But there is much more to the story -

The initials A.H.B. can be found on many of the circuit diagrams of Benchmark’s early products dating back as far as 1983. These are the initials of Benchmark’s founder, Allen H. Burdick. He personally designed many of Benchmark’s early products.

Allen had a life-long passion for audio, and he became one of the leading innovators in the pro-audio industry. The AHB2 is named in his memory.
