I'm trying to put together a system from existing components and could use some advise from experienced HT folks. I have a Panasonic TH-50PX600U plasma tv, a Yamaha DSP-2070 amp., a separate Yamaha RX-v670 receiver that I use as a tuner and to power to outside speakers by the pool, a Sony PS3, an NAD 5100 CD player. Speakers are B&W Matrix 3 fronts w/ a B&W center channel and sub and Paradigm Atom surrounds. My main concern is all components except the TV and PS3 are non-HDMI. Will I need some sort of interface to get the most out of the pic and sound, or will non-HDMI cables suffice. I do have good quality component cables as well. Also, will the PS3 handle all my "disk" needs and can I forgo the CD player?
Any thoughts would be appreciated. We're having cabinetry built and I don't want to build shelves for components I'm not going to use.
