Budget?
Most of us here use Roon with a Tidal or Qobuz account to supplement our existing music library.
Some use a ready-made Roon Nucleus, while others use a custom-built Intel NUC with Roon ROCK.
Either a Meridian 218 or 210 is the obvious choice for streaming Tidal/Qobuz content via Roon to Meridian DSP’s.
You can even add a Sonos Port to a Meridian 218 (ideally via Coax) for access to most, if not all, streaming services that is controllable via the Meridian app on your preferred Tablet/Phone.
