I have both, and I’ve spent numerous hours comparing the two. In my experience/system, one doesn’t sound superior to the other across the board. Some tracks sound better via Tidal, and some tracks sound better via Qobuz. I find the differences in sound quality between Tidal and Qobuz to be negligible at best, so I use Tidal as my Roon default. Happy listening.
Qobuz and Tidal comparison
They are doing serious demonstration.
The conclusion is that Qobuz give more realistic bass and nuanced details than Tidal.
It is because that Tidal use more compression.
