I meant to write analog, on that second one.
And the third one is product of forgetting what the conversation was about.
Fourth, signal quality differs over distances of cable. Optical cables are far better for keeping high-quality signal than electrical cables, enough so that 20' optical cable can be the quality of 5' of electrical cable. The receiving end therefore has to do less guesswork (if it does any at all, if it doesn't then it just sounds worse), meaning that the original audio is better-maintained. Also, optical cables look cooler when the sleeving's taken off than electrical cables do.
