I just purchased an Onkyo TX-NR708 receiver.  My cable box and Sony blu ray player both output HDMI.  My Sharp LCD TV has HDMI input.  I intend to run HDMI from the blu ray player to the Onkyo and HDMI from the cable box to the Onkyo.  Then run HDMI from the Onkyo to the TV.  My friend says I should also run optical digital audio from the blu ray player and cable box to the Onkyo for better sound.  Does that sound right?

Just using the hdmi cable for audio is all you need. It's digital just like optical and coaxial. There are some who believe optical/coaxial is a tiny bit better as hdmi is thought to sometimes have a "jitter" problem but I sure haven't experienced it. And hdmi is required for Dolby TrueHD and DTS Master Audio which are not available through optical/coaxial.


"Everyday room": Panasonic 58" Plasma, Dish HD DVR, Pioneer Elite vsx-23, BDP-23 BR, dv58avi universal dvd player, Paradigm Studio 20 V1, CC-450, Dayton HSU-10 subwoofer.

"Movie/Music room": Toshiba 65" DLP, Dish HD receiver, Marantz 7005, CC-4003, BD-7006, Polk LSI25's-LSi7's-LSiC, 2 original Dayton 10" "Mighty-Mites" subwoofers. (subject to change without notice).
 
Also have  MB Quart Vera VS05 +.....too much to list. Help me.

+1 Your friend is a few years behind and you will  want to have the HD audio formats that HDMI allows.



Every child has many wishes. Some include a wallet, two chicks, and a cigar, but that's another story.
