Re: IMHO, the spec argument, misses the mark entirely...

Actually, unless you go way over CD's sampling frequency, and word length, there's no way a digital system can compete with a "cost no object, balls to the wall" analog system.
To use my example from above, a 35mm 3track magnetic film chain with no noise reduction I measured at within 3 db from 20 hz to 35kHz, with 16dB of headroom and > 80db signal to noise (> 96dB dynamic range). Those numbers mean that 50kHz reproduction at reasonable level is not out of the question. You can't get 50kHz out of even a 96kHz sampling system (Nyquist). 50 kHz is not out of the range of music--see a paper by James Boyk of Caltech where he measures the > 50khz part of the spectrum for various instruments--it's at 10% for a ride cymbal, 2-3% for a harmon muted trumpet, etc. That's a lot of music to be throwing away.
So unless you go bigger-- bigger rate, bigger word (and the allocation of bits at the low volume end of the digital word sucks, at least for 16bit, IMHO), digital is still not as good.
