DVD audio output: Optical or Digital RCA?


My CAL DVD 2500 has an optical audio output and a digital RCA audio output. Which one would you use? I am asking this because I am running the signal through my DVDO iScan HD for LipSync (the picture improvement with this unit is VERY nice with my Samsung DLP!). The DVDO has both of these inputs. Is there really any difference in sound quality? Light pulses vs. electricity... Hmmm Please let me know what you think! Thanks for looking... Paul

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.
Many thanks to those of you who replied to my questions! I had a feeling these would be the answers I would get. I suppose I was looking for a little "reassurance" so to speak... So now tell me if you will..., which brand of coax digital cable would you recommend?? There are so many different ones out there. I am just looking for the best "bang" for my buck! Thanks Again! Paul
