G'day, All this high quality digital audio is encoded and decoded in a clean background, high S/N ratio environment. Seven and eight bit coded telephony has a surprising quality but there again the background noise is low. I have long had the feeling that signals in the presence of noise just don't work so well.
Certainly a lot of magic can be accomplished in DSP. Is it the answer to life the universe and everything, I feel the jury is still out. There is a danger of falling for the digital hype, if it's digital it must be better. Unfortunately what we get is a steady erosion of quality in the name of progress. Good analogue design is an art but once built a particular design is set in stone compared to pushing bits and doing math. Much of the good stuff in the K3 is still in the analogue domain.
