Digital Output, Optical or Conventional Coaxial?


Just curious about this, which digital output, optical or conventional coaxial, do you prefer to use from your CD, DVD or Blu-ray/HD player do you prefer to use when connecting to a processor? Why do you prefer one connection over another?

Personally I use the optical digital output from my Pioneer Elite BDP-94HD player to connect to a Krell 7.1 HT processor. Sonically, there is no obvious difference between this and the conventional coaxial link. However, there is absolutely no hum on the optical cable link.

optical from hdtv tivo, coax from cd, component digital from dvd---why? cause senior engineer at mcintosh told me to do it that way.....some people i listen to....
Duh. What is component digital? Is there a principle hidden in these recommendations? In other words, why?

Sound wise I have found them to be all the same. Choice dependant on the gear outputs and available inputs on other gear in use. I have some components going into two others. Such as tv and preamp etc.
