Very happy to report that the following method works too if you have a large library on TIDAL that is not easy to navigate in Control:PC or Mac

1) Launch TIDAL Desktop App
2) Create a New Playlist
3) Queue the Master Albums into the New Playlist
4) In Control:PC, select TIDAL>Playlists. New Playlist will appear
5) Play from this Playlist to get MQA files. In Control:PC, fileformat says TIDAL but on hardware it says MQA.

Zone 1: DSP5200SEs, 818v3, Sooloos MC200 (1 Master, 1 Slave), Samsung LED 55" TV and Bluray
Zone 2: F80, MS200
