I am not educated in the audio/visual world. I am starting my system with a Jvc hd-52z575 rear projector. I have picked out Athena tech. audition as-f2 main speakers. and an svs cs- ultra sub w/1000 watt amp. The center channel is also probably going to be an Athena.

Now for alot of questions.

1) What am I looking for in a good a/v reciever? what is 7.1 vs 5.1 sound?

2) What about amplification? How many amps does a system need? I know the sub needs its own amp. IS a good a/v rec. enough or what? and/or pre amps?

3)Surround speakers? with the Athena mains can I use bookshelf speakers? any thoughts on what to use?

4) Cables? silly question- does anyone have a wired house? (Trying to put this question in a non-idiotic sounding phrase but it is not working.) Do you have to big monster cable run in the walls or is the norm running the cable on the floor next to the wall? Where do you get the outlet covers for the in-wall set-up?

Please help!!!!!!!!!!!!!!!!!!!!! I am looking for a good system with a reasonable price. In advance Thank you for any/all advice.
