Is there any update on this?

Primephonic is Classical only streaming. Personally I am finding the catalogue deeper in areas I am interested in than Qobuz. I really like the navigation and the focus on expert human curation in terms of themed playlists and discovery etc. Not sure how that side of Primephonic and other streaming sites that emphasise expert curation over algorithmic automation could be preserved in roon. On the other hand the replay connectivity options are very basic in Primephonic. That is not something I find an issue particularly but I assume any RAAT integration with roon would certainly improve that.
