I have a KEFF Series 3000 5.1 surround sound system ( 8ohm speakers ) and sub woofer. The AV is Denon AV 2310.

I recently changed my TV from a Sony Bravia Full HD to a Sony AG9 4K. Therefore I need to change the AV
What would be my best option :
1—— Sony STR - DN1080

2——Denon AVR - X2700H

3—--Denon AVC - X3700H

Thanks
