"Does it follow that some digital cables are better at delivering digital signals free of or with less added jitter?"
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.
"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?"
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.
