Why do digital cables sound different?


I have been talking to a few e-mail buddies and have a question that isn't being satisfactorily answered this far. So...I'm asking the experts on the forum to pitch in. This has probably been asked before but I can't find any references for it. Can someone explain why one DIGITAL cable (coaxial, BNC, etc.) can sound different than another? There are also similar claims for Toslink. In my mind, we're just trying to move bits from one place to another. Doesn't the digital stream get reconstituted and re-clocked on the receiving end anyway? Please enlighten me and maybe send along some URLs for my edification. Thanks, Dan

Some people, convinced that digital cables cannot make any difference, claim that people who can have to be under influence of placebo effect. They don't realize that their strong conviction makes them unable to hear the difference because of negative placebo effect.
I am convinced that digital cables can make a difference, but in practice to date, I find that the differences attributable to cables I have used alone are not nearly as significant as many other factors and that once I have a handle on the big fish I do not find much to inspire me to tackle testing different digital cables alone. Its just not been worth it in my case to date, not to say it may or may not be for others.
A friend lent me 4 digital cables. 3 sounded the same but one sounded very different. You just have to find there "one"
Jim, can you provide more details? What kind of digital cables? How were they different? Construction? Length? Brand? How did the one sound different? Better? Worse? Did all seem in good condition?

I'm still trying to find out what does matter most with these things. Length is one factor that I have heard can make a difference alone.
Kijanki, I am also interested if you hear differences using the same source with different cables and your jitter resistant Benchmark DAC.
