The whole thought that USB cables can sound different just sticks in my craw.From a technical standpoint, and speaking as an experienced digital and analog designer (not for audio), I would not find it at all surprising if there were sonic differences between USB cables. USB cable differences could affect RFI that might be radiated from the cable and couple into arbitrary circuit points elsewhere within the system, with unpredictable effects; ground loop issues; noise pickup; waveform integrity; jitter, etc.
However, assuming that the cables are reasonably well made I see absolutely no reason to expect much if any consistency or predictability of their sonic effects from system to system, or from one physical arrangement of the components to another, or even between different lengths of the same cable type.
In other words, although I would expect there to be sonic differences, I would not attribute specific sonic characteristics to specific cables. And I would expect that the only way to determine which cable will work best in your system, among a group of candidates that are of reasonably good quality, would be to try them in your system.
IMO, FWIW.
