Sorry George,
you are the not really correct on this matter.
RF GaN business is totally different and requires different type of transistor design than the one needed in power management. Among other things, RF GaN transistors are Depletion mode type, so they are normally "ON", not a good start for any power converter circuit. So they are not applicable/usable in Audio (and in all other power) applications.
