Are these the correct Roon settings when using a Lumin U1 Mini streamer with a MSB Discrete DAC (Pro USB)? I used to directly connect my MSB Discrete via usb from my NUC/Roon Server and would see the MSB in the signal path. However, I recently added the Lumin streamer and no longer see the MSB Discrete in the signal path. The MSB still shows MQA when playing MQA tracks so I assume it’s still working?
If you can see MQA indication from the MSB, then it’s fine.
You may experiment with setting MQA Capabilities to “Renderer Only” and see if it sounds better to you or not.
