After reading a thousand or so of these, I'm finally going to make my first post. Just sold my paradigm reference studio 20's, cc-450 center, and denon 2700 and will be starting all over this week. I went and auditioned the polk audio lsi9's and was really impressed. I've decided on the lsi25's as mains and the 9's as rears because of space reasons, and after doing some research, settled on the denon 4800 as my receiver of choice. Being 4 ohm speakers, will the 4800 be a good choice to push these? Any other recommendations in the $700-900 price range would be welcome. Thanks in advance
