""If there is information in the original signal that the ear/brain can discriminate down to the 20uS range, does bandlimiting (and therefore the subsequent A/D/A) have the effect of eliminating/smoothing/smearing that information?""peterMy take? absolutely.
In fact, take a look at a 44Khz sample rate of a 15 Khz sine wave..The reconstructed waveform looks like three 1 Khz sines superimposed in three phase..so the peaks are riding three crests..
The only way to get back to the real wave is to reconstruct with a wide window, whereas cd replay is point to point..Blowin Nyquist theory out the window..
