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

I would probably have to agree with the possible theory that differences in cable geometry(or connections) will cause differences in the delicate structure of sound to different degrees.(my theory..and only a theory). I DO FIND that cables sound very very different often, and DO AFFECT THE SOUND MORE DRAMATICALLY IN BETTER MORE RESOLVED SYSTEMS for sure. I am indeed a believer, from working in 5 high end stores, and being around high end audio and custom install for more than 20 years now, that cables make a difference!
I also find that the trend amoung those advocates that cables ALL BASICALLY SOUND THE SAME(if matched from a mechanical impedance standpoint, etc), THEIR SYSTEMS TEND TO ALL SOUND POOR OVERALL!!!
I once had a long conversation with John Dunlavy(Thanks john for the contributions to audio) at his factory about cables. He is an advocate that "CABLES IS CABLES" basically. The irony there is that his systems in his factory where, HANDS DOWN, the single WORST SOUNDING set-up's I've ever heard from a "HIGHER END" speaker manufacturer!!!! Infact, other people touring the factory were asking me why his speakers sounded so bad....I litterally had to defend his speaker's "merits", and say that "I'd gotten much better sound from his speakers elsewhere!"
On another occasion, I was at CES in Vegas a year ago, where I stumbled in to a room set up with Merlin VSM's with some nice high end gear. I asked the guy running the room "what wires and cables are you using?" He actually looked at me and said "you're joking right?"..."surely you don't think cables make a differnce, do you?" I said, "no comment!" I proceeded to listen to the set-up when he started playing the music, and IMMEDIATELY BOLTED UP FROM MY CHAIR!!! Not only did I hear the most bright and analytically sound from any of the rooms I encountered during the trip, but everyone else in the room immediately took issue with the sound as well! I didn't even stop to say anything to him...I think he pondered it all on his own from that point out.
My experiences, basically, is that the "cables-is-cables" advocates, are usually "closed-in" with their thinking, and can't see past their brains!!(limited processor and hardrive I presume...) These are the one's I usually find have the poorest sounding, if even well intentioned, systems!..go figure
