You’re right - its does say something about the WiiM app - its high quality. I talked to my wife’s husband (which concerned my wife) and what he likes a lot about ROON is management of his own content, Having thousands of albums, he finds locating music quickly on his Home Music Server (Western Digital MY CLOUD) is painful compared to ROON. Also the seamless integration of Qubuz playlists to ROON is also appreciated,
