Hey all! I wanted to ask your opinion. I have an old Yamaha RX-V2700 and an thinking to upgrade to a Sony STR-DN1080 for the sole purpose of 4K HDR. Atm i am obligated to connect every 4K source directly on TV and send everything to the receiver via optical output of TV which on pc gaming for example means stereo only... I know all this will be a thing of the past with the new receiver when it comes to video. But the thing that i need the expert answer to is for audio. Yamaha was a very expensive receiver and i am wondering if i upgrade for 4K video will i be making a downgrade in sound?
