I believe you're fine on MQA support. Meridian will continue to support Sooloos and will add MQA support.

As it is an audio end point (apart from Store and Core and UI), I would expect that you can use it with Roon as such.
But would need seperate NUC / Mac Mini style device to run Roon on and tablet to navigate.

Then C15 could probably still serve as storage over its samba share.

In short, on the Meridian track you are fine, on the new Roon experience, perhaps the C15 is not the most optimal device.
