The only good thing about vinyl is the RIAA curve prevents loudness wars. If CDs were mastered correctly without intentional clipping it would be impossible for records to best them in quality.
Nyquist–Shannon begs to differ.
N-S requires, for instance, an analog signal which is perfectly band-limited. This implies that it must be of infinite duration, which, obviously, is not the case.
However, it is plenty infinite-ish enough for all practical purposes.
