Class A Solid State Sound

This is the reason I put up with the downsides of Class A amps, namely, heat, weight, and cost, cost of the amp and the cost of additional electricity. I haven’t heard any other amp topology that gets me as engaged with the music as Class A.

Correct there’s an effortless ease to the way the music is presented with Class-A, big transients are not squeezed out at you and shot at you from the drivers, instead coming out and washing over you like a huge musical swell.
Yes Gryphon!! probably the best high bias Class-A amps one can buy in the retail market today, and can do enormous current down to that 1ohm courtesy of their Bi-Polar (BJT) output stage and power supply.

"Green Bias" though is another incarnation of Krells plateau (sliding) bias.
Which for those who would like to know, was invented in Australia by my boss Steven Deratz in 1980 and had a provisional patent on it, but nothing came of it, and he let it lapse.
I actually have always preferred the fixed (user adjustable amount) bias of the Gryphon Antillion Evo’s and my amps.

I have ME amps also bjt output, some of which can also be user adjusted fixed Class-A bias.

Thanks, George.

The Gryphon Colosseum has three user selectable bias levels, Low, which is 30w Class A, Medium, which is 70w Class A, and High, which is 165w Class A. I can tell the difference and prefer running at High, but that’s hard to do in the summer. Still, I live in a northern city, so most of the year, I can run High without heating up my apartment too much. 

George, that is one crazy amp, haha. My rule is, if I can lift it, I don’t want it. Is ME mainly confined to the Australian market? I have not heard of them.

They were much in the line of today’s Gryphon Antileon Evo’s, maybe that’s where they got the ideas from.

Believe it or not these were made back 1990’s by Peter Stein of ME Sound (ME stood for modular electronics), as the ultimate statement to hi-end solid state amplification, most went to the Chinese/Japanese market.
They were shown at a US show but were severely let down when every time they were pushed into the very inefficient speakers they caused the hotels circuit breakers shut down, so they weren’t received too well, as well as being from Australia (nothing good comes from Australia we all know that) I don't think you yanks ever forgave us for taking the America's Cup away from you for the first time ever!!! Then we send Paul Hogan (Crocodile Dundee) over there to sort you lot out.

Later Peter Stein’s 1st wife divorced him and he survived that divorce so did the ME Sound company. But yes the idiot got married again, and once again got divorced, and settlement caused ME Sound to go down, never to recover. (what’s that old saying once bitten twice shy) he didn’t listen.

These amps used "probably" the best BJT output transistor ever made, the now defunct boutique manufactured Hirel EB203,204 (PNP) and ED203,204 (NPN). Each was spec’ed at 20amp 200mhz 200w and super linear, the ME-1500 I posted above used 24 of them.
Here was a little talk on them at DiyAudio

Here is a token website he put up, where he still services them, maybe one day they will get going again.

I just got modest Burson Audio Timekeeper amp, Australian company, and though they don't advertise it I have an impression that it operates in Class A until certain point.
Yes, Gryphon separates is a dream stuff.
