I've been debating which receiver to upgrade to for a while now and really appreciate your input. How does the Marantz compare to the Yamaha amps, in terms sound (quality and tonally)? I've been looking at the Yamaha 3900 and the new Yamaha 2065, I know they are both more expensive amps than the Marantz, but I need an amp with 2 HDMI outputs. Will I be missing out on any features if I opt for the Marantz?
