I think Radio Paradise sounds pretty good but in my system Qobuz sounds best generally with Tidal being very close.
I would expect the Innuos to be pretty good across the board. Any chance they are not set to max resolution in the set up menu?
My Vault 2 does not let me select quality but my Aurender does in the log in screen for paid services. In fact i just checked mine and somehow Tidal was set to HiFi instead of Max Must have happened at last update.... wondering if it's something simple
