Why is there a difference between any two cd/dvd players in audio if you're using them as digital transports only? It would seem to me that a digital signal would be the same coming out of any source, since error wouldn't be tolerated. I mean if a computer cd was read with errors, a program wouldn't run correctly, so how then could error be the reason why an audio cd would sound different? Is there a parity bit in computer cd's that doesn't exist in audio cd's to prevent any error? If that's the case, why wasn't the audio cd made with this in mind? That's the only possible source of a difference I could think of. I guess i'm more confused than anything. Thanks for any replies to this in advance, i'm really curious as to why this is.
