Yes, a dumb question from a Home Theater newbie. Bear with me, and thanks (in advance) for the clarification. Ok, I just bought a Hitachi 51 s500 TV. Nice, nice. So I want to get surround sound. I see places that offer a 5-speaker setup (Fluance, etc.). Alriiiight.... is that all I'd need? Buy this surround sound speaker set... plug 'em into the back of the ol' tv... and voila? ...? Or is there more to a surround sound audio setup than that? I'm not looking for cutting-edge technology or anything--- I just want my sound and music coming from all directions. I guess what I'm asking is if I'll NEED to buy anything other than a 5-speaker set. amps, receivers, etc. Thanks; great forum here.
