Hi all i have a dennon 3802 that I blew so I'm gonna upgrade. I decided to go with seperates and have a couple of questions. Would I be able to use an av reciever say a yamaha 2700 for a preamp? And if so what will make the sound the power amp or the reciever? I don't know much about seperates and that is bugging me I dont want to go spend a couple of grand on a power amp if the reciever is gonna dictate the sound. Also i would like opinions on power amps I'm looking at a rotel 1095, adcom 7807, earthquake cineova 5 channel, b&k 7250 series 2,sunfirecinenama grand,and a couple of different parasound amps. I would love to have an anthem p5 but cant find one in my price range. I'm running klipsch legend series speakers and my room is 22x17 with a 19 foot ceiling so I loose alot of sound going up so I need the wattage well I think anyways. I really like all kinds of music but really want to be able to seriously rock out some Korn, Zepplin or old Rush, but I don't want to kill my movie experience either. Sorry for such newbie questions but I just don't know alot about power amps. Also if anyone has these amps or other opinions would really appreciate the info and opinions. I 've been racking my brain for 3 weeks now on this and everytime I decide I read something about a different amp and then that leads to another and another LOL please someone stop the room from spinning.
