Many listeners, including myself, find that Qobuz CD and hires SQ is superior to Tidal. But, what is often overlooked are the many remastered albums on streaming services. You need to make sure to compare identical albums.
Not always possible, Tidal and Qobuz may not offer the same version.
Variable stream transmission quality
I recently acquired a dCS Rossini Apex dac, with the idea of moving away from CDs, but I find sound differences between TIDAL and Qobuz when playing the same song. I have also noticed that the sound quality in general changes from day to day, so I thought about going back to the CD. I wonder if it has to do with the atmospheric condition that could affect the Stramer transmission?
