Interesting. Seems to be a ways from commercialization though...
GaN Class D amps are already outdated, it's time for GaN on Diamond!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. :)

@jaymark You are most likely correct. I thought it was interesting that the semiconductor industry has been playing around with synthetic precious gems since the late 1950’s. There was a recent article about HP using silicon on sapphire technology for floppy disk controllers, with a ridiculously low chip yield of 9% (i.e. 91% of the chips didn’t pass basic quality testing). |
There is so much more in design then one component in the design one great part can help but it is the sum of the whole , the quality too of the other parts used ,let’s see how it goes. many have used theGan transistor as a marketing ploy give it a fancy case and chsrge $20-$30 k for mono blocks I won’t say the names but several smaller companies used to be within reason now they think they are gold . I look much more for quality at a fair price the fancy machined case doesnot justify these over priced items IMO. |
