Why do digital coax cables matter?


Could somebody please explain this to me? Why does a $100 dollar cable sound better than a $50 cable. Why is silver coax better than copper coax? Why do the quality of connectors matter in the digital realm?

I'm currently needing a cable for a Stello U3. Some people claim that are no discernible differences out there b/t different levels of coax cables. They say the only things that matter are impedance,cable length, and adequate shielding.

They sound different to me. I've tried several budget brands and I have found them to sound noticably different. Logically, they should not sound different since it's sending discreet values, not an analogue electrical stream, but they do sound different. The only explanation I can think of is that the clock signal is sent on the cable and therefore there can be jitter introduced by different cables.
