I went with the 2807 for HDMI inputs (2) and output (1). It's not many inputs/outputs, but at least it will handle the DVD player and projector in my HT (which is all I really want).
I also went with the M60 Axiom speakers and they are great. I chose the SVS sub over the Axiom package sub just based on hearing people's reviews and it is all I need.
don't know if that helps much, but I'm happy with the 2807 and Axiom and would highly recommend them to others.
