@auxinput, I have also considered switching to the Anthem AVM 60. Do you have thoughts on that pre? I have seen nothing but stellar reviews, but when I demo'd their power amp, I wasn't blown away. Granted, this would not be doing what the amp was supposed to do.
I have honestly had some 4K pass through issues w/ the 7011, which is partially why I also want to upgrade/swap. For some reason, NONE of the rear HDMI inputs will support 4K from my Oppo 203 or PS4 Pro. When I use the front HDMI port, it works. But on the PS4, it only allows one of the 4K resolution types to display...its quite odd. Neither Marantz nor Sony has an answer. I figured upgrading to a pre that solely focuses on video could alleviate the problem.
Sorry for all the questions - I almost bought an Anthem a while back, but I have no way to demo it....
