I was using eclipse to describe only technical matters - and since I do not understand the technical merits of either Roon or its competitors (hence my original question) I was raising a question and not making an assertion.

I have little feel for the sales of Roon or even Sooloos, but I suspect they are low volume, specialist products - only Sonos seem to have become really successful in this streaming marketplace so far (pace Logitech who backed away for reasons I do not know just after I had bought my Squeezebox Boom and Squeezebox Duet!

Perhaps I had better not get Roon for fear of blighting their prospects.
