By the way, what can you tell about Roon as an active user? It costs as much as Qobuz, but it’s your responsibility to fill up your library and provide infrastructure - which is weird. Sure, it sponsors musicbrainz and lastfm for metadata and puts some nice UI, gets buddies in HiFi manufacturers, but what else?..<p>I’m very surprised that Roon does UNPnP for own port, potentially exposing home network through some zerodays. For that money it has to do reverse tunneling or something like that.
