Mapman,
The Doppler effect in amplifiers is not actually a different problem than the one "solved" by NFB. It is the root of the problem that NFB cannot fix by design.
NFB is a servo system that only works for steady state sine waves. Not for complex music.
Even if you use massive amounts of NFB - you cannot remove Doppler. It is the wrong tool.

Roger
