I am looking for a reciever to power a 7.1 home theater. I just returned my Pioneer VSX-1015-tx cause it was lacking. I am looking at the Yamaha for now, any opinions on this or any other reciever? I would like plenty of power to drive my Polk RTi8's, RTi4's, FXi3's, CSi5. Im running a PSW505 sub also. I would like all up to date ins and outs, like HDMI. Opinions?
