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.
