@audio-b-dog Roon architecture is different than jplay or mconnect. It consists of 2 components - roon core that’s an application that runs on your pc or mac and that is your Roon Core. The iPhone and iPad apps are just Roon remotes. You can also run Roon Core on their own Roon Nucleus machine.
Downloading and installing roon app on your phone or iPad with running roon core won’t work.
Roon is great especially if you have local music library on hard drive. If you only stream qobuz or tidal, use jplay.
As to sound quality…it will most likely boil down to master. If you have a better version on LP, it will beat streaming.
Try the Cassandra Wilson high res on qobuz and compare to LP.
