Santa is rounding up all the stuff and will arrive shortly. Now I need to know how to connect it all. He is bringing a couple of RTiA5's and a CSIA6 center. An HK3600 will drive it all. Already have a blue ray player and LCD Sony 46" tv. A couple of rear speakers will arrive later in the year. I am assuming all components go into the receiver via HDMI. Now I need help with cabling. What are interconnects? Don't the HDMI cables interconnect everything to the receiver? I see interconnects for some crazy prices. Do they handle audio better than HDMI? Anything special about speaker cabling. Is it best to order with connectors or just wrap wire around receiver post the old fashion way? My application is primarily home theater. Thanks for the input.
