Exactly what I have done!
Nucleus as my Core (server), hidden away, and an iPad as the control point. Roon was the (way to go.
While my perfect world scenario (a B&O designed control point) is not happening, at least Roon provides a pleasurable experience when picking up an iPad.
Its pretty nice to be able to use Roon to operate my A9 and BS2, and my BL50s / Linn combination (hell, even the Linn streamer unit has 6 physical my buttons, able to start playlists, albums, radio stations)
Pretty flexible, and of course the Roon UI is fabulous.
If you are looking for a sound system, I can highly recommend Roon Software. Additionally a Roon Nucleus if you are looking for an "out of the box" solution.
The user interface of Roon is just awesome. It connects your local media with Hi-Res Audio streaming from Tidal and / or Qobuz. Additionally, multiroom is offered via Airplay, Chromecast, Sonos, LMS or Roon.
If you are looking for an impressive touch control (not comparable to Nativ Vita Player), you should watch the YouTube video
Another advantage for me was that thanks to Roon I managed to break away from my 100% B&O eco-system. The first were my kids who thought Sonos was much cooler than B&O. No I have a mixed set-up of different brands managed by Roon.
