IMO, there is a legitimate concern about mixing and matching perceptual coder
mixing and matching. Every coder throws away music that it thinks won't be
heard. Not all coders throw away the same things. If you route music through
multiple stages of different perceptual coders, the possibility that audible
stuff is thrown out would seem to increase.

One "hot button" concern of mine is the fact that I can't edit MP3 files
without putting them through another cycle of encoding and decoding. I don't
think this is theoretically necessary, at least for simple edits with limited
precision, but that is the current state of the art. I'm of the opinion that
multiple decoding and encoding cycles, even within the same basic technology,
could leave significant, audible deficiencies that would not be there if only
one cycle of code/decode were used.
