My suggestion would be to look for a Marantz 2252B, 22565B, 2270, 2285, etc. and a pair of Klipsch Fortes and I think you will set for now. Or maybe a pair of Klipsch Heresys and a sub.
Hey, I had a Cambridge Audio 840a connected to a pair of Klipsch Fortes and it was awesome. The CA can be had used for about $550-650 and the Fortes for $350-500. When you get a chance, do a search for "Bob Crites Networks". He sells titanium diaphragms for the tweeters and new crossovers. That will run about $260 and is a very worthwhile upgrade.
Again, the only reason I suggest this is becasue it worked quite well in my room.
