Hi Scott,
I have the MPS-1 chassis with two emp-300 monoblocks for now to drive my m80's. I'm still using my Denon to drive my center and surrounds for now and using it as a pre pro for my Emotiva amp. Later I plan to add additional mono's and 2-channels to complete the system.
The HDMI 1.3 thing is not a biggy thing to me right now. Down the road that may change. I will most likely get an Emotiva PrePro some day. I'm sure they will be coming out with new models over the next year with advanced features.
I can tell you this....you won't be disapointed by their performance or quality. They use the best guts inside, and are designed from the ground up by Emotiva, nobody else.
