It’s unlikely that the 210 is at fault.

Unless there is some method within mconnect or Tidal to directly link the Tidal Servers with a 210 it will not be possible to play MQA files “via Wi-Fi” from the iPhone to the 210 (since Page 1 of the 210 User Guide clearly states that communication between a phone/tablet and 210 is via Bluetooth).

UPnP on the 210 is for connecting either a HDD/SSD - and then using mconnect on a phone/tablet as a remote to playback music - or by using Audrivana on Mac/PC, FireStream (Mac), or some other Windows UPnP playback software on a PC. By these methods an MQA stored CD will correctly play via the 210 via its UPnP input.

IF Toony’s iPhone was miraculously somehow able to connect to the 210 via ‘Wi-Fi’, the 210 would require an IP Address to identify itself on his home network. This does not exist.
