Yes, I understand that. Let me rephrase: I am very surprised that you are hearing what you are hearing simply due to changing the data cable. The change you made is prior to any jitter, and signal-induced noise, any processing of the music signal, digitally or analog. Changing digital cables, be they USB, SPDIF, toslink, firewire, AES or otherwise, makes sense, as does changing analog cables. But data cables...well, I guess "everything matters".
