Get a better avr if you are going to get the RF 82's, they can take more power. I like higher midrange Pioneer's with Klipsch. I use a Pioneer SC 35 with my Klipsch. If you check the used market or go on the Klipsch forum there are some great buys to be found and the speakers are in mint condition. You have a nice system. Get a good Bluray player and you will be good.
