My STR-DN1050 (6-7 years old) seems to be on its way out. The centre channel output becomes very soft, unless I restart or change inputs. I do like the Sony sound and UI and I think I would prefer to stick with a Sony. Our setup is 5.1 and I doubt Atmos is in our future based on our room layout. 7.1 is definitely out of the question.
Most of our AV devices are plugged in to the TV and the sound runs over ARC to the receiver. Our Nintendo Switch, Sonos, and turntable are connected directly to the receiver. So I don't need a multitude of HDMI inputs, but need to be have analog audio inputs. I also want to stick with Sony for the ARC, since our TV is Sony. I know it shouldn't matter, but ARC compatibility seems to be all over the place.
Since we use Sonos, networking ability is not required.
The power output on the 590 is a little less, but we don't listen at loud levels so I do not believe that is an issue. We usually have the 1080 between 12-20 on the volume dial. I occasionally go as high as 30-35 but that's rare (only when the kids and wife are not home).
I bought the 1050 years ago because it was the top receiver in the Sony series, excluding the ES stuff, and I am OK paying the $800 CDN for the STR-DN1080 if there is a compelling reason to do so. But in looking at new receivers, I am thinking the STR-DH590 would be enough and I can pocket the $450 price difference compared to the STR-DN1080. Is there anything I am missing in my logic? Or is there a better way forward? I like the idea of separates but don't like the prices.
