dCS Bartók Apex + Tidal MQA: Filter M1 not auto-selecting? (Mosaic)

Hi everyone,

I’m hoping another dCS user might be able to help me with a small but persistent issue.

I have a Bartók Apex and use Tidal as my music source via the Mosaic app. According to the documentation, when the system detects an MQA stream, it should automatically engage the M1 filter, which is specifically designated for this format .

However, I’ve noticed that this is often not the case. The system frequently fails to switch to the M1 filter automatically, and I have to go into the app and select it manually.

Since this is supposed to be an automatic process, I’m wondering if there is something I need to do to correct this on my end. Has anyone else experienced this issue with their Bartók or Rossini?

Is performing a factory reset still the recommended fix for this behavior on the Bartók Apex? I’d prefer to avoid resetting all my other settings if there’s a simpler workaround.

Thanks in advance for any insights!

Tidal no longer supports MQA as it is defunct. Tidal has spent the past 18 months replacing the files with flac versions <24/192.

So you may well not find the MQA filter displaying as what you are playing is not MQA.

Hi Pete, thanks for your comment

If that’s so, why the Bartók screen shows MQA? Is that info not correct?

Lima , your query is why Bartok does not show MQA. I understand from other Tidal users that there may be a few odd titles remaining in MQA that have not been replaced. However as you will see from the Tidal statement that I posted it is not available at least officially. So you might occasionally find one by luck ( just like there are a few MQA titles on Qobuz but they never did support it). If your Bartok is only showing the MQA icon then that may indicate an issue.

I still come across several files that are identified as MQA by Roon and the screen on my Vivaldi stack. I do not have to manually select MQA for them to play properly.

Maybe include information on the exact album in question so that others can try it out and see if it’s a generic issue or just with your setup?
