Why do digital cables sound different?

Mapman, you are testing my memory. I believe they were all 1.0 m and all in good condition. The brands were Elco, Legend(?), Virtue, Monster, and some unknown cable. The Elco was the best.

Kijanki, let me make sure I am tracking with you. You are saying that jitter is important. That jitter can also result from cable induced errors. That re-clocking at the DAC does not necessarily correct for all/any errors related to jitter that could occur during delivery of the raw digital signal through a cable. Does it follow that some digital cables are better at delivering digital signals free of or with less added jitter?

On a related note, in theory or in measurement, can a digital signal be corrupted in a cable, say due to exposure to strong EMF, to the point where 1s and 0s are actually deleted or unreadable at the DAC. I.E. outright data loss?

I cannot speak for K. but clearly there are always differences between two products. The question is more how much these matter in practice. I tend to think that any good quality product will deliver excellent results for most people in most cases. There are probably always exceptions though.

That's a good question. Of course it is possible. DIgital gear is inherently a source of noise and may be affected as well. I think the former is a much bigger problem than the later. I encounter it to a great degree with my setup. Noise control is important. SOme wires may shield against it better than others and I think that can make a difference in most cases where detailed listening is involved.

There are obviously some on here that do not know how music is represented digitally.
