i may be wrong, but i'd say the quality loss is pretty much negligible,
as long as you use the same decoder and quality settings for re-encoding.
a few years ago, i experimented with gradual degradation of repeatedly
encoded and re-encoded files for artistic purposes (using an mp3 codec),
and the amount of "degradation" was disappointing, to say the least...
i guess what happens is the psychoacoustic model removes information,
when you decode, the new wav has all those simplifications in it, and
the next encoder down the line has nothing left to do.
