Emotiva have a pretty nice receiver that you might want to consider, the Fusion 8100. It currently sells for $449 and Emo will allow you 30 days in-home trial. It has honestly spec'd. amplification, unlike most HT AVRs, and a good room correction system. It also comes with a 5 year warranty - *much* longer than the competition.
I bet this would sound pretty darn good with the speakers you have...
