Qobuz.

I can do the same with my Roon. But to get the second, and the final MQA unfold, you need a MQA DAC. So not completely MQA you are comparing, and not fair

Of course it is unfair. Qobuz is true 24/96/192 where Tidal MQA is at best upsampled(unfolded) to 24/96 or 192 if it goes there. Ive been using Qobuz for months, and most anything that you can find in MQA on Tidal can be found in a true hi res version on Qobuz.

My Roon friends report they already can sort albums and have filters for hi-res selection.

You can sort for Qobuz Hi Res in Audirvana too!
