Roon is great. Marvelous sound quality. Tunes both Qobuz and Tidal for me. As well as my own stuff. Roon radio is great; I just listen to something I'm in the mood for and it goes on to play tracks from albums I never considered. When it plays something I really like I add the album to my listen later group and move on.
Harmon has added a much more customer focused aspect to Roon. New software developments are better as is the customer service, still by forum though. Most of the time there are no issues except for the folks who want to design their own nucleus tuning process to run the core program. Usually to be clever and save a few dollars. Often their stuff doesn't work and they blame Roon. The program is based on a fairly complex internet access which seems to awry for some folks with less strong connections or fluky IP providers. That said, works great for me, Buy it on an annual subscription. It is not for the I want free music crowd.
