Oppo media control.

iPhone 2 yrs.  iPad 3 years 

If you have the MSB UMT and judging by the manual, it looks like your transport supports DLNA / UPnP. You can use mConnect Player HD - link - to stream Tidal from your iOS device to the transport. Just select your transport from the list after you tap on the ’Play to’ button.

Yage:   Thank you.   mConmect works well but I think it streams to UMT as in Airplay.    The original OPPO Media control app used UMT as the streaming device.  Also mConnect does not control cd player on UMT like media control 

mConnect uses a different protocol called UPnP / DLNA so it should stream hi-res without a problem. I've used it with my Raspberry Pi and Mac based streamers before and it worked perfectly.

It won't control CD playback, that's true, but at least you can stream Tidal again.

I successfully streamed Tidal on Oppo Sonica Streamer/DAC with MConnect, easy to set up too...
