I've just started playing with Roon and for $120 a year and I'm almost certain to keep it.
It comes across as a substantial upgrade to Sooloos (which I'm guessing is how it was designed) and, compared to the cost of an MC200, seems reasonably good value.
That said, how many people outside of the serious Hifi market see this as good value is another matter and I would probably have planned to stay on Sooloos longer had I not had a spare (and silent) Linux server lying around.
The fact it can turn the Meridian system off and stream to other devices when I'm finished with it is the icing on the cake.
