I have both Tidal and Qobuz running on my Aurender N200 and Vault 2i in sys 2. They both sound excellent but I have to give the edge to Qobuz. Tidal has some great live recordings which is why I keep it.
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.
