I have just got my Yamaha 663 and will be connecting it in about two weeks (darn moving woes).
I have some older DVD's with 2 Ch audio as well as newer 5 ch stuff, and I know not all cable signals are created equal.
My question: I plan on connecting analogue(Red+Wht) for 2 ch, digital optical for other, and component for video (don't have an HD TV, yet!). Do I need the redundancy of the RCA or is digital capable of outputting sound in all instances?
Thanks and Happy Listening
