DVD audio output: Optical or Digital RCA?

Always go with coax when a vailable. Most manufactures build in optical because of cost. Direct wire is better in all applications, expecially longer runs

If you are talking about DVD-A then you will need to go with analog interconnects from the DVD-A player to the pre/rcvr to get full potential.

If yer just talking about audio output from DVD, i reccomment coax first and foremoest because it cuts out a converion from electrical to light then light to electrical, and anytime you convert something like that there has to be some type of affect.

Also, dont be fooled by these "High Quality" optic cables. None of them hold a candle next to the capability of telecommunications fiber. I used to do a lot of work with fiber optics in the past, this stuff is all pretty low grade if you ask me. Then again, not many audio companys are going to put multithousand dollar transciever units into a dvd player. LOL

You might want to to to www.fatwyre.com and give them a call and sample the lending library. I got talked into trying some cables that I would never have even considered and I borrowed some from them and I got my chance to decide for myself.

Yes, as a matter of fact there is a difference between various fibre optic cables.
