Any more updates from Marantz support on your end? They told me I needed to buy optical HDMI cables (!!!) despite the fact that I told them the same cables don't produce banding connecting directly to my TV, and then stopped responding to me. They've never acknowledged that this is an actual issue.Regarding the banding that the SR7010 causes when receiving some 4:2:0 or 4:2:2 signals, which I've previously shown pictures of, this is what customer service had to say:
It has not become a known issue. This issue is currently being investigated and handled by a product specialist at our corporate office they are handled on a case by case basis.
