Since I didnt see you specify, what is it that you use your setup for - primarily movies? If yes, what is the display you use, is it a TV or a projector.
If its a TV, moving to a projector screen is going to be a far bigger upgrade than adding an AVR.
sud98,
Earlier I didn't realize, but now I understood a PJ is far bigger upgrade than adding an AVR. Recently I bought EGATE P513 projector, and I am loving the overall setup. You are right !!!!
