Dang, thats a killer HT setup you have there with the EP500!
Others have covered it well. The entry level HD receiver market seems to be very competitive right now. The RX-V663 dosn't have a lot of extra features, and is limited in HDMI inputs, but it sure hits a nice price point for HD audio and video. It also has pre-outs, a surprising feature for such a low priced receiver and a good thing to have if you think you will ever get hit by upgrade-itis and want a pair of M80s
I'm sure the Onkyo mentioned is also very good.
