Yesterday, Roon released 1.5 which does first unfold of MQA. It allows DSP to occur on the MQA stream. Apparently, there is a known issue with the current fw of Bridge II that causes many dropouts to occur when using DSP with MQA. Turning off DSP in Roon resolves the issue, or setting the DS conf…

I needed to change this setting on my DS Jr. Looking at the Roon 1.5 Feedback Thread last night - there was a question about (Maybe it was yours brett?) As, I can’t find it this morning. But, yes - changing the device settings: MQA Capabilities from Decoder and Renderer to just Decoder worked for …

Found it! 1.5 with DirectStream BridgeII - dropouts MQA with any DSP

That’s it. I believe the Roon boys may have come up with a novel method (working with MQA) to unfold, apply DSP, and retain the authenticated info. Something isn’t happy in the BridgeII with this method but as you say, setting the DS in Roon to ‘decoder’ works around it for now. Brett aka Larry P…

Thanks Brett, I found your thread last night while Roon was updating. So, I knew exactly what to change. Hopefully we’ll get an update in the not to distant future.

@brett66 Thanks for sharing the information…

+1 Same issue with the Bridge II and the DSJ.

Does the MQA DSP feature work over USB to the DS or DSJ?

Not the full decode and rendering. The Bridge II is responsible for the final rendering. You would only get the first and arguably most important decode in Roon.

Would that mean - over USB - that Roon would unfold the MQA and apply the DSP filtering, and all of that would be received as MQA by the DSJ? Or would it still be a Roon Wav signal? I guess I just need to be patient for PS Audio to send out the software update!
