Here is a decent article that puts some science behind the claims of vinyl
superiority.

Nyquist theorem states that a non-variant signal freqency can be
reproduced that is 1/2 the sample rate. Unfortunately, music that is
invariant is not terribly interesting. Thus, the common wisdom that
44.1KHz sampling can reproduce 22 KHz music is not true.

A seminal paper from MIT shows that distortion related to sampling must
consider both the sample rate and the target word size. For today's
CDs--that is 16 bits. Thus, according to this paper, a minimum of 8X
frequency is required--10X is better. Working backwards, that means that
CD technology can only reproduce, at best, 5.5 KHz before distortion
starts to enter in. This is independant of the construction of filters
and assumes a boxcar filter (impossible in real life.)

Other solutions have worked hard to reduce this problem by oversampling,
adding bits, etc. All these solutions smooth the distortion created by
the original system, but they can not add information back in that is
lost. What they can do is create better sounding music by smoothing out
the jaggies in the distortion.
