Sorry for asking someone else to do my homework for me. If you have a completely current technology system, is there any sound quality or audio format flexibility reason why I should connect any of my sources to my HT Receiver using optical or coax instead of running all audio through HDMI? If it matters, I have a Marantz SR5008 receiver, PS3, Oppo DVD (wired for 5.1 analog), Motorola cable box, and an older XA2 HD DVD. Thanks.

No, HDMI is the say to go. It had the added advantage of passing the latest surround codecs.

Just curious... from the devices listed (other than possibly the Oppo), which one passes the latest surround codecs?
HDMI is probably a better choice simply for convenience and eliminating cable clutter.
