Hi,

I have a DSJ connected via Bridge2 UPNP to Tidal via MControl Android app.  
Since the latest update, the DSJ display does not show MQA or MQA. when playing Tidal master MQA files but instead UNK.

Any idea what that means and whether it reduces the input quality?

Thx  
Chris

Hi Chris, I get the same thing when streaming MQA with Tidal. The Perfect Wave Dac shows UNK in the display I think its normal. Great sound quality anyway for most music not everyrthing.

Thanks Chris D.
