Jkalman,
Thanks for the links. It seems to corroborate my statement that interface jitter is a well known problem when devices are synchronized using a clock signal - or am I missing something? The way I see it, a long run of HDMI cable might behave differently from a short run. I agree that good quality equipment should effectively handle the interface jitter in both cases to the point that either cable is indistinguishable to the ear in double blind tests. I was only trying to point out that in some cases of borderline equipment performance then an audible difference "might" occur. I realize some authors have suggested that as much as 20 ns is necessary for jitter to become audible and since there are infinite forms of jitter the debate may never be resolved, however, it is easy to show that certain forms of signal correlated jitter will indeed rise above the noise floor at 100 psec on very high quality gear (whether this is audible or not - this simple fact has a tendency to cause concern because S/N is such a standard specification in our industry and modern electronics has incredible S/N performance).
