Trying to decide between Denon 890 or 990, or go with Onkyo 807. I will be using these to power Polk Monitor 70 for fronts, Polk CS2 for center and not 100% sure on surrounds but probably polk FXia 6. And a pair of polk in walls for Surr. Back. I want something I can keep for a while so that if I upgrade my speakers it should not be a problem. My only concern with the onkyo is the heat issue reported on some of the older models, dont know if this one is any better. The reciever will be in a built in rack. Don't know if it matters but I will be using this with a pj (probably Epson 8500UB). I know there are fans of both brands but with what I'm planning what do you guys thing would be the best fit?
