My long term thoughts are I'll keep Roon even if I find my proprietary music player to have superior sound quality at some point. Roon SQ good enough to be totally engaging and even more important, the great interface has turned me on to so much great music and artists new to me. Qobuz and Tidal also offer this, but Roon far superior, Roon radio is simply awesome with it's analytics, graphics suggestions same awesomeness. Finally, I don't know how well the other proprietary players organize local libraries, but my Stylus players completely destroys organization of local library on NAS, makes library unusable. Perhaps it would do better with streamer internal drives?
Bottom line for me is Roon cost so little it would always provide more than commensurate benefit. Being able to transfer it to nearly any brand or custom build streamer is another added benefit.
