Ditto. I also got an XPA5, in spite of recommendations to get the XPA3, because it was bigger, cooler, and in stock. The XPA3 had a backlog of orders. I finally admitted to myself and this forum, (but not to my wife), that the XPA3 would have been more than adequate. Now I have 200wpc to my L/R surrounds. Dogs barking, doorbells ringing and background crowd noises sound great! (That's me being sarcastic. The surrounds get so little sound, 200wpc is far from necessary.) The AVR has plenty of juice for the surrounds.
Plus now I have an AVR that provides 125wpc X 7 channels, driving only my rear surrounds.

They get even less than the L/R surrounds.
So for the cool factor and bragging rights, go for the gusto. I'm not disappointed with mine. It's not bad. No harm, no foul. I've just come to realize it wasn't necessary.
