An excellent review thank you, which also introduced a couple of options I hadn't considered.
I was surprised that there is no mention of any Onkyo A/V receivers, e.g. Onkyo TX-NR797. Any reason for this?
Pretty disappointed in you Tom's Guide..You listed the Denon X2700H as your #1 on the AVR for 2021 however you didn't list the HDMI 2.1 bug as a con for this AVR. This AVR suffers from the HDMI 2.1 bug just as the X4700H you have listed further down the page on your listings. I personally own the X2700H & have had to suffer with this HDMI issue, it sucks. For me personally the "HDMI adapter kit fix" that Denon sent out to it's customers has not fixed the issue for me. I still have issues when using the adapter kit & my Xbox series X. Really disappointed in fact that Denon hasn't came up with a better solution for all of it's AVR 2020 models that have these issues. You should consider putting the HDMI 2.1 bug as a listing on the con list as well for any Denon 2020 AVR models you recommend.
