Hey all...I'm a novice in this game and have a question. My setup is a Denon x2300 receiver..a Paradigm cc570...EP500 sub..M80 mains...and Q8s. Would my best option for a little more power be to upgrade my receiver to one that has pre=amp inputs and then get a amplifier..or just jump up a few grades and get a better more powerful receiver? was thinking of just getting a x3500 and then pairing it with an outlaw 5 channel amp..Or if i went to a x4500h...would that be enough? any ideas or thoughts? Looking for the most cost effective way to do this...Thanks!
