USB from external hard drive to mac mini


I vaguely understand why the quality of USB cables carrying an actual digital audio signal can effect the quality of sound. Something to do with timing and jitter and waveforms. But I swear that I can hear a difference between USB cables running from my external hard drive to my computer. This doesn't make sense to me because the data is in blocks and there is no timing issue.

Has anyone else heard a difference between USB cables used in this application, or am I hallucinating again?

The one effect that I can envision possibly being relevant is that the quality of the shielding in the cable will affect how much rfi/emi (radio frequency interference/electromagnetic interference) is radiated from the cable, which might be picked up by and affect circuits in the dac or elsewhere in the audio system.

Obviously the likelihood of that being a significant effect would depend on the proximity of the computer and the hdd to the dac and the audio system.

So you may not be hallucinating! :)
