HDMI cables are all the same?

the same hdmi cables i uesd for audio, i also connected to the tv set from the cable box. i noticed differences in clarity and color saturation. for example, the cardas was clearest , but bleached. i have used hd 1.4. note, as dielectrics and metal changes, wouldn't one expect that differences would be visible ?

The HDMI standard is particularly prone to jitter, so the sound has the potential to vary more than for SPDIF cables. I find that the picture varies significantly as well. The Wireworld HDMI cables are the best I've tried -- significantly better than 2 Belden based Bluejeans and numerous cheapies I've tried. I'd imagine that the same technical factors which allow digital cables to sound differently, apply to HDMI. Among these would be a variance on edge triggering. If you really want to get tweaky, you can apply mechanical damping and RFI damping to your HDMI cables.

Here is a survey of reviews discussing differences.

I asked the Cable Company to suggest a high quality HDMI cable, a good value and one that would show a real difference with the Future Shop stuff.

Their proposition: Wireworld Starlight.

The image quality enhancement is so obvious, if you don't see that, just give up.
