The phase shift vs. frequency characteristics and square-wave distortion
reasons are summarized very well in the "Computers & Electronics" article
on CD players a couple of months ago.  It seems to me that, yes, those phase
shift characteristics are completely trivial compared to the phase shift
vs. frequency characteristics that characterize a symphony orchestra in
a concert hall.  Speaker manufacturers tried to make much of this by
setting tweeters back from woofers by a few inches, a few years ago.  Just
another "new speaker design!" gimmick.  I doubt that ANY distortion
(phase, etc.) in a CD player is audible at all.  

Certainly, however, most of the software available is not up to the
rest of the system.
