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.
