Andrew, I do have Tidal and occasional encounter MQA tracks. M1 is typically automatically selected (including the track in question in this thread). I don’t recall ever otherwise.
As a point of interest, IIRC, dCS is the only DAC vendor to allow a non MQA filter to be manually selected for an MQA track (not sure how dCS managed to wrangle that into the MQA licensing terms 
)
Yes, my point was that the product seems to be behaving correctly, i.e. according to the documentation. So if Lima, or anyone else wants to change it it would be considered a feature request rather than a bug.
I’m assuming there was a reason it was done this way, I’ll see if I can find out.
Are you saying that even after you’ve selected M1 as the filter for the MQA track, when you next come back to that track, it reverts to some other filter?
Hi, Yes, that’s whats happening
OK, my Bartok definitely does not behave that way.
You should probably get your dCS Dealer to have a look at your unit maybe 
Same here.
Here I am playing the same track, first from Qobuz, where it is tagged as standard red book:
and then on Tidal where it is tagged as MQA studio:
I have not touched the settings in between. When played from Tidal the Bartók is sensing the MQA studio tags and selecting the M1 filter which I have chosen for this media type.
The only way my Bartók goes to a dealer is to come out as a Rossini + Clock 
That’s surely one good way to solve your MQA problem
