The problem with 16-bit sample depth is not so much sounds recorded near 0dBFS, but what goes on at low levels where the resolution capability is severely reduced. -60dBFS is represented by only 64 levels in a 16-bit system. With 24-bit sample depth -60dBFS is represented by 16384 discrete levels.
Many seem to believe that a CD retains full resolution all the way down to the noise floor - so as long as the music is above the noise floor all is fine. Actually the Red Book standard is sort of a lossy standard as the clever designers thought that the weaker the signal is the less important it is. I have tried to record the same music (a piano trio) from my SACD player at -48 dBFS peak in 16-bit/44.1 and 24-bit/44.1. I normalized the tracks to -1 dBFS peak and listened to them through my SB2->Tact RCS2.0->Tripath->Tannoy system. The difference is quite dramatic!
