There's a large range in prices for 7 channel AVRs. Going to 9 channels is a lot more expensive. (Example: Denon AVR-X4300H, $800 at Amazon and elsewhere.)Well damn! I've been thinking this in circles over nothing. This whole time I could swear it was Atmos... :crying:
Thanks for the help and research. I missed what was in plain sight.
Purchasing a new home soon. Now to contemplate if its worth it to purchase a new AVR capable of Atmos for the theater room.
Elsewhere, someone pointed out that Amazon has the Yamaha RX-V681 on sale for $300. I've never seen a better 7 channel receiver at anything near that price.
It has also been promised a Dolby Vision pass-through update, but I believe that it has not gotten it yet.
I toss out those suggestions, although it sounds like buying a new AVR probably isn't one of your top priorities at the moment, completely aside from the cost.
