GaN Class D amps are already outdated, it's time for GaN on Diamond!


The title is a bit of a troll for everyone who kept saying that Class D wouldn't be high-end until GaN transistors appeared.

But the truth is advanced GaN transistors on diamond substrates may be coming soon, further elevating the switching speed and power efficiency.

Will they sound better?  Meh, I like early 21st century Class D. :)

So the emotiva xpr 1 shiftr to class h in300wpc to to2 k wpc some of the old carver i think is class h like . Look at the specs on the emotiva xpr 1 it's as good as my michi m8 mono blocks

Yep, Carver definitely had some early class H designs. Some of them would go up in smoke too. Much later he realized his switching speed was too fast, and he’d end up in what we call a "race condition." Meaning, you have two circuits racing to be first, and sometimes it was a close tie and zap, short. :)

Of course, race conditions happen in software as well.

I believe in Carver's case it was a matter of one circuit not shutting off fast enough, sometimes.  IN that case you'd have two different voltage rails essentially short to each other, and hilarity ensued.

Have several carver amps including tubes all on surge protectors hope that keeps the house from going up.i like the 760x the specs on those are good but that was some of his last ones. They don't have grounds on the plug have read some shocking  experience as well
