Pioneer VSX-82TXS vs. Denon AVR-2807 vs. Marantz SR5001

I've narrowed my search for a new receiver that will hopefully warm my system musically while decreasing the overall brightness of all my RTis; at the same time, I want an amp that has the balls to push the soon to be purchased Fxi3s with the already owned Rti6 and Csi5.

Does anyone have any experience with either of these receivers on a system similar to my own? What are your opinions of the Brands? If you had to choose, what would you go for?
