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.

There are differences to me. In a word, it may come down to jitter. Some cable designs adversly influence jitter more than others and all the physical elements of the cable design are in play. There are at least 3 kinds of jitter induction: optical, electrical and mechanical. Coax cables may affect both mechanical and electrical jitter. Insulation (less is more) may also influence the sound (openness) as well. Lots of people prefer silver in this application (I use copper and am very satisfied with it) and it may be due to the higher frequencies than with analog, but I'm leaving those with more of an ee background to expound on that. My cables are not shielded as I believe this also constrains the openness a bit (at least with analog IC's, IME) and I believe should ordinarily be avoided unless you have a discernable problem with interference. But, Mlsstl is right - no matter which way you go with it, there will always be someone to tell you you're wrong. Regards.
