If you don't want to host Roon anymore, WiiM really is the shit. I only use Tidal Connect, Spotify Connect + sometimes Airplay and I never, ever open the WiiM app. Like ever. But the WiiM app is pretty good anyway! No real complaints here. It lets me listen to English radio in the U.S. as well really easily which I really appreciate - but that's just a me thing.
It can act as a Roon node. It can not act as your Roon server. You'd still need a computer/Nucleus/NAS/Rock to do that. Sorry if you knew that already and I misunderstood your previous message. Just assumed you were trying to bin the laptop altogether cause you said 'replace' :)
