I just received my new Epic 50 system from Axiom, and after setting everything up, I'm a bit underwhelmed by the performance. I can certainly appreciate the great clarity these speakers are producing, but they seem to lack the 'oomph' I was expecting. I suspect my receiver may be to blame. I currently have a Yamaha RX-V630, which outputs 75 Watts/channel. I'm considering upgrading to a Denon, either 2803 or 3803. Would I notice a marked improvement by switching to one of these? And if so, how much more of an improvement would the 3803 bring over the 2803? Worth the $200 premium?
