I can stream wired through the BluOS at mqa quality OR I can use the Tidal connect app to get flac, but only connect wirelessly. So I thought Tidal had solved the flac issue but if its only wirelessly then I will need to stay with mqa or go to Qobuz on the BluOS app.
@mojo771 You can get hi-res FLAC from Tidal's own desktop apps (Mac/PC) on USB output.
On 3rd party streamers, only a few vendors so far have completed updating their software to support Tidal hi-res FLAC (I know of Linn, Volumio and Lumin). Roon says they are working on it, and no doubt BluOS is in progress as well.
