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.

Assuming the cable is properly constructed and terminated, then in the digital domain, it is "bits in, bits out" as far as I'm concerned... Or at least until blind or ABX testing proves it to me otherwise.
Jitter is measurable, correct?

Will a cable of some determinate length not add some measurable, repeatable, non-arbitrary amount of jitter within a particular range of measurement, regardless of any jitter coming from the source component?

Are there any cable manufacturers that measure and publish jitter specifications for each of their different cable products and cable lengths?
