Hi all new to board. I could really use some advice. I'm looking to buy a receiver I have a denon 3802 right not with klipsch legend series speakers and rs 5 surrounds. I really liked the sound I get out of the set up I have but I blew up thereceiver and its not the same after it came back repaired so looking for a replacement. My room is 21 by 17 with a 19 foot ceiling.One thing I'm looking to get out of the new receiver is to be able to play concert loud with good clarity. Nothing beats the new korn dvd or the zepplin dvd cranked. The receivers i'm looking at are denon 4306 1500$, 4806 2400$, yamaha 2700 1100$ all new. Or these refurbished denon 5803 2000$ denon 5805 about 3500$ or the yamaha rxz9 around 3000$. I also went and listened to an arcam 350 new at 2500$ it didnt impress me but the speakers hooked up to it were pretty cheap I'm gonna bring it home and home test it next week. The receiver has to sound good for movies and be able to make me think I'm at a concert. Any advice or opinions would be great cause my brain is over loading and I just want to be rocking. Thanks again!
