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?
