IGBTs in an audio amp sounds really odd to me, I'll bet a set of
FETs could have been dropped into it perfectly.


** Switching PSUs in many high powered audio amps use IGBTs - often in
parallel groups. The topology is a driven, square wave inverter - no
feedback or regulation is needed.
OK, in the off-line DC power supply section, this makes perfect sense!
Not in the audio amp section. (You can probably tell I rarely get into
late-model consumer audio gear.)

Thanks,
