I have heard people claim to be able to detect the
difference between wav files and mp3s before, but I have
never been able to detect the difference myself.
(Probably worth mentioning, though, is that I used to jam
in a garage with a cement floor and stood next to a
very-meanly-played ride cymbal for years. I can't hear
voices over night-club volume music any more.)

What should I listen for to try and detect the
difference? Any certain cymbal sizzle or anything else
that would be a dead giveaway?

One approach is to encode the same piece of really clean music at
increasingly higher bitrates, starting around 32 K bps, and working your way
up to 320 k bps, roughly doubling the bitrate every step. The convert all
the MP3 files back to .wav files and compare the various .wav files to the
origional .wav file using the comparator softwawre you can download for
free from www.pcabx.com to compare the files, in synch. Start with the
lowest bitrate file and work up.
