The use of Gallium Nitride (GaN) semiconductors has been around since the 1990's. GaN FETs have gained popularity in recent years in power devices like laptop battery chargers as they can be made even smaller than just a couple years ago and produce even less heat. I have one that's 1/2 the size of a deck of cards that can charge my laptop in a couple hours.Amps that use GaN FETs are still Class D amps. Not all Class D amps are equal even those using the same technology as we have experienced over the years. For example the ICEpower Peachtree Class D amp that I had sounded terrible. Same for the ICEpower Bel Canto S300. My Wyred4Sound ICEpower monoblocks were very good while the PS Audio were excellent. My Hypex nCore amps didn't sound so great. My present Purifi Class D amp is also excellent.
I'm sure we will experience terrible sounding GaN FET amps just like we have with other Class D amps.
The point being, GaN FET is not a game changer in Class D amps - not yet anyway. I'm taking a wait and see attitude. Waiting for more capable designers to implement them in their products. And then we'll be able to weed out the bad ones from the good.
