I spoke with tier 2 guy. Yamaha is not really admitting these things are lemons and blames the banding issues on the Apple TV 4K. He wondered why anyone would want the receiver to do the 4K upscaling anyway. So, I guess it's ok if it doesn't work since my TV can do it? He suggested it might be my cables and thought the idea of everybody having issues with these units was far-fetched. After telling him about all of my devices and the different settings I used to try to get them to work, he thought I "got a dud" and told me to take it back to Costco. I will do just that and put my money toward something else. Oh, he also said that Yamaha cannot say when features like Dolby and DTS height virtualization, HDR10+, VRR, ALLM and QMS will be activated via firmware update because they are awaiting testing materials from the HDMI consortium for the HMDI 2.1 features and do not expect them until early 2021. I was not impressed with Yamaha support. The guy sounded a bit arrogant and dismissive and I wonder if every brand is going to try and sweep this HDMI 2.1 fiasco under the rug as well. Yamaha is blaming Apple and HDMI for some of it's problems. Denon and Marantz might blame the XBOX Series X or the PS5 for some of their own. So, if you get the RX-V6A/TSR-700, you better be content with it's abilities right out of the box and hope those features actually work. I would advise against it and I would also say that if you have one, take it back. Nothing says "F#%k You!" quite as nicely as "I Want My Money Back!" I'm off to Costco this afternoon. I won't take Larry this time. He'd probably try to talk me into a f#%kin' soundbar.
