Help with speaker set up??

Im having troubles deciding on what set up to go with. At first I was thinking about going with all klipsch reference. After some thought and looking at how things will work out i have started thinking about Using Klipsch mains, center channel, subwoofer and a set of Speakercraft Aim8threes for the rears. I am just wanting some input on seeing if this setup would sound good? Reciever is a Denon 2808. Thanks!
