I am having the same issue with my NAD C388. I can only play MQA songs from Tidal if I disable the MQA core decoder in the advance settings for the amp.
I’m having the same issue on my NAD T758. With MQA set to “Decoder and Renderer” I can’t play music from Tidal. With MQA set to “NoMQA Support” the music plays.
This issue is probably low priority for the support team but it happened exactly when I got my system to a point where I might be able to actually hear what MQA can offer. Any progress updates would be appreciated!
We’re still working on investigating this issue and we’ve reached out to NAD.
No specific updates I can share at this time, but we’re looking into this.
Both the BluOs and the Roon updates were minor ones, if you read the relevant change logs.
I ended up just changing my Tidal settings to Hifi from Masters and then I don’t have to worry about it. I do not believe that one can hear a difference between the two - unless they are from different masters.
I found switching the m32 to turn off mqa renderer stops the error but I believe there is likely a quality reduction. My roon core is close enough to the Nad that I can use usb audio as well but it is a bit less convenient as I have to manually turn Nad on
The NAD T778 is not yet a Roon Ready device and as such we cannot make any comments on what capabilities it has with Roon until certification is completed.
