I am in the market for a new HT receiver in the approx $1000 range. Currently I have the quintet system with a KSW 12, but plan to move up to the Klipsch Reference Series (RF-3, RC-3, RS-3).The receivers that I have been looking at are the Pioneer Elite VSX- 45TX which has THX select, the Marantz SR 8200 THX, and the Denon AVR 3803. All of these receivers have about the same output and features; however, I noticied the Marantz doesn't have any component in/ outs. Does anyone have these receivers or know anything positive/ negative about them? I have been leaning more toward the Denon b/c of name, and it's dual room capabilities; however, it is not THX certified. Does the THX certification really make that much of a difference? All help is greatly appreciated!
