A pretty positive review of Roon in the latest print edition of the Absolute Sound. (Sorry there is no online link available.)
They don’t like the lack of a manual and provide a lot of setup and how to use details.
They like the sound quality but though the sub-title of the article touts Roons rich metadata there is almost no discussion of that, no mention of focus or discover and how the rich metadata is really used and made available and enhances your music collection. Only a brief mention of the Tidal integration as well.
To me reads more like a review of a traditional music player and misses what is really special about Roon. Shame the Roon we know did not really get out there to a wider group.
