I too
wondered
this - Am I right in believing that there is absolutely no error detection
(or
correction) available in an audio bitstream from a CD - is it not just a
stream of analog sample values ?
If so and
assuming the 1's and 0's are decoded reliably then I am guessing that the
differences come from the jitter (lock) and the edges of the serial data
switching - I can see that a varying speed motor for example would cause
problems but it would seem reasonable to expect that most 'fair' products
should be almost identical in performance once the a/d is done
offboard
- indeed I would expect it to be very difficult to pick out a top end
player
from a mid or even low one in a blind audio test - or am I missing
something
here ?
I know
putting
my Sony CD multi-changers through the Tag McLaren AV32R has made them sound
fantastic, previously one was just ok'ish and one was really awful - now I
can't tell the difference.
I really
cannot
believe that people can tell the difference between digital interconnects -
analog maybe but the technical reasons just aren't there for digital -
particularly optical. Maybe my hearing is just not up to it and I think
that
is Phil's point that at some stage the improvements , whilst technically
there, are lost on the listener.

A bit off topic but I
know we have some audio buffs out there.
What difference does
it make to the sound quality between using an expensive or cheap CD
transport or interconnect lead assuming the AtoD conversion is being
carried
out in the amp, surly the data is digital,its ether there or not
so how can it be changed by the hardware?
