I find that Roon is consistently inferior to using a UPNP server like Minim or Asset. I always assume that is because it decodes the flac files it serves to my Linn streamer, unlike the others which serve flac files directly.
Well I would. If it is anything like the difference I experienced. The wife in a blind test picked the UPNP over Roon in 100% of tracks!! It is not a small difference.
