Digital cables and power cables make no difference to the sound quality. They either work or they don't.
You can hear a difference with some analogue cables though. The good ones don't add any noticable distortion so they all sound the same because they can't make the original signal any better than it already is. Bad cables that do add distortion can make it worse though and I suspect this is what often gets mistaken for an 'improvement' with some of the overpriced audiophile cables.
(I know this comment has been cut and pasted from another cable thread but the point is a valid one and is worth repeating for anyone new reading this. 🙂 )
If you think that the power will go through a very thin piece of wire, also called the fuse, I agree that under normal circumstances, the kind of power cable used shouldn't make any/much difference. If however you live in an intereference intensive environment and I'm not talking partners, a shielded cable or at the very least some sort of noise supressor close to the power inlet of the unit, can indeed make a difference, at least in my experience. - That goes for pretty much any analogue cables.
