Are you sure? I thought that was just a problem particular to early encoders for the Vorbis codec, which were alleviated by altering the tuning parameters of the encoder.
I'm basing it purely on modern (Within the past couple of years) encoded 320kbps/V0 MP3s.
I have not done any personal blind ABX tests on AAC or modern ogg vorbis, so I can't really speak to them.
I'm going to keep 'archival' quality stuff in FLAC anyway, just so I'm covered for any advances in compression tech or whatever, and I stream to my mobile stuff, so size concerns aren't a huge deal for me. My ABX testing has just been for the sake of the mp3 vs FLAC argument.
So, AAC and Vorbis might have very well solved the problem of compressing some of these instruments.
