HDMI Cable comparisons

People who think they are hearing and seeing differences with different types of digital signal cables are suffering from the placebo effect. Don't believe the bologna...

There is a well known problem of interface jitter from transmitting the clock signal along with the data. I would agree that in the scheme of things this form of distortion is usally pretty small nowadays (compared to other problems like speaker distortion) but nevertheless it provides an example of why a digital cable might make a difference.

If you are just copying data from one drive to memory or to another drive and teh clock signal is ignored - then I completely agree with you and do not believe the bologna.

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).
