RE: CD players
Title: RE: [ukha_d] CD players
I t o
wondered this - Am I right in believing that there is absolutely no
error detection (or correction) available in an audi 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 t 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 audi 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 audi buffs out there.
What
difference does it make t 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?
