Sorry, intended to agree with you about CDs/DVDs using compression/not using compression. Edited my previous post to fix the typo.

In terms of capture, missing a frequency range sounds like it compromises 'fidelity' in some audible sense if those ranges are indeed audible--all of this as compared with analog media.

Simply asked: Is it possible that someone could hear and prefer/dislike the sound of audio recorded at above the threshold described by the nyquist theorem?
