Hey there polkheads. I have just bought a complete Polk speaker system, which include Lsi9's for front and man rear, Lsic for center, FXi5's for side surround, and the psw1000 for sub. Now i need to decide on a first class receiver. I have come down to two brands, denon and pioneer elite. I am willing to spend around $4000. Does anyone have any expeirence with these two brands and high end polk speakers?
