Greetings!

This reminds me of my second setup where I drive an F80 but it could be a pair of DSP8000.2 as well.

LG C2 series OLED >optical out (configure for external stereo PCM optical out speaker setup)
218 - optical in, MHR out to DSP Speakers

Now this takes care of all TV-related audio. For Tidal many of us use Roon hence the ’NAS’ recommendation but in your case unless you have lots of offline music I would stick with a single

Roon Nucleus

That’s it. You don’t need a NAS unless you need massive offline storage for music.
