Finicky in what way? The audio seems to take longer than the Marantz did to kick in when I start playing content on my PC. I haven't used other devices enough to know if it's across the board. I also couldn't get 4K 120 Hz from my Xbox Series X, but then I remembered the 25' cable from the AVR to the TV isn't rated for that. Ordered a new one from Amazon, though I won't be heartbroken if it still doesn't work.
