Passing uncompressed audio and better sync. I actually went with a SHARC and go eARC out the TV to a standard input on HDMI. So I no longer need HDMI 2.1 for all of the gaming features on an AVR.Curious, what excites you about EARC? I.e., what's the intended use?
On 2.1, is that only for 8k? Need a new processor for my basement hybrid theater, and have an AVM60 upstairs which is now going on 4 or 5 year old. Was shocked that Anthem didn't have an updated version for it yet!
But at the same time, not sure what is "missing" from the line up in terms of features, and also have come across "EARC" and 2.1 as what appears to be the real only missing "features".
