Hello, So I have a bit of a newbie question. I am in the process of building a new home and would like to setup a nice, simple, home theatre system. I am having all my wiring run throught the ceilings for my speakers and have chosen to go with the Polk Audio RM6750 5.1 speaker package. The speakers will be attached to a Harman/Kardon receiver (either the AVR2600 or the AVR3600, not sure yet). The cheaper receiver, the AVR2600 features 4 HDMI inputs and 1 HDMI output. My question is, what would I connect the HDMI output to? For the inputs I plan to plug in my TV (model not yet chosen), PS3 and Blueray player. Would I run an HDMI cable from the output, back to the the TV? What else is the HDMI receiver output for? That being said, the receiver also features 4 Component Video Inputs and 1 Component Video Output. I know these connections are quite dated, but with the three items I already mentioned that I want to plug in above, is there any reason to use these component connections? I can't imagine what I would require to plug into them. And finally, any ideas of what else I can connect to the receiver? Like I said, I'm not looking to build a crazy expensive system (as I'm sure you can tell by my audio choices), but something that can entertain the wife and I on weekends and such. Many thanks!
