I'm not sure I get it either, but I'm going to guess and say you want to know what the preferred method of hook up is????
For me it would look like this:
1) CD player - ANALOG (RCA's)
2) cable decoder box - OPTICAL ONLY
3) DVD player - COMPONENT & DIGITAL COAX......but does it have DVI? or if It was a universal player, I would also go with RCA's for 6 channel audio (SACD, DVDA etc)
4) Anthem MCA3 II amp - RCA's are fine. I have yet to hear a system where XLR's made a night and day difference.
5) Projection TV - (DVI-HDTV input, component video, S-Video) - Your order looks right to me in terms of preference. DVI if your source has it.
6) Sub output from receiver is single coax. - Which is all you need.
