  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

12-12-00: Blues_man
Gmkowal 2 points here. It ought to be obvious that your test is inadequate, simply use a CD source. It should take about 4 seconds if memory serves me to fill a 1 meg buffer of SPDIF data. That's real time. When I say jitter can not be measured accurately I'm simply pointing out that any device that measures jitter has to have a clock, that clock has jitter, so your measurement has to be off by some amount. That amount may be small but it always exists. My point was that many claims of jitter reduction devices are total BS. 1439bhr I thought the Levinson also had a proprietary data transfer interface. My point was that some component combinations do and they seem to do the best job. My points were simply that jitter reduction devices are a poor substitute for a good implementation between a DAC and transport. They may even incrrease jitter. My second point is that the jitter on most "good" systems is low enough to not be a major factor in the sonic degredation. I believe jitter is third behind errors in the transport and signal loss of high Khz signals.
