Those are some pretty Cantons! I’m using some old B&W 804S that I purchased nearly 20 years ago. Looking to upgrade soon, but they still sound great.
I tried using the Apple TV with the optical out of the tv to the RD160, but it doesn’t sound right. Samsung might do better than LG for that though. I am really impressed with the Zidoo media player for movies, though only good for your own media, not streaming Netflix, Prime, etc as its missing the certifications. There are Dune players that have streaming, but no USB audio except for their highest end model. Another option is an eArc audio extractor (to toslink).
The RS130 can play non-Dolby Vision content, but the video performance is poor, as well as the interface. You do not get a system to view/catalog your media, and navigating a video is near impossible.
