Interesting. I've tried Roon for their free trial but decided there was very little that Roon offered that BluOS didn't. In fact the only worthwhile feature I found that Roon offers that BluOS doesn't is their "Radio" feature where additional tracks are added to the expired playlist based on previous selection. Good, but I found this list degenerated quickly into ADVISORY labelled tracks that I didn't want. Also Roon combines subscribed-to streaming service offerings with one's own Library of music, but I'd prefer to chosse where I look for music first - but that's a minor advantage / disadvantage of Roon!The Bluesound app really is no where near as good and comprehensive as Roon, far far from it.
However the BluOS is a good basic package and one of the better ones, its far better than the Auralic Lightning DS App for sure.
What else does Roon offer that BluOS doesn't? I'd like to know as I'm thinking of looking for a possibly upgrade from my M33 and may have to return to Roon as many streamers (including the subject of this thread) fall well short of providing a proper control app..
Thanks. Peter
