I finally added an amp to my rig! Its a Carver AV-505 that my friends bought me for Christmas. I couldn't be happier, I hooked it up to my center and mains and it sounds fantastic. There was a big upgrade in clarity and volume, especially in the mids. My RTiA5's sounded good before, but they really woke up when the Carver was driving them. Its rated at 80 x 5, which is only 5 wpc more than my AVR, but the difference is dramatic. I hit 120 clear db's at the listening position during the "Comfortably Numb" solo, and there was more power available. Can't say enough about Carver. Will post pics and further reviews soon.
