Interesting that multiple people report opposite conclusions on which one sounds better. Maybe this is due to personal preferences in sound or, as @nyev mentioned, there could be other variables at play. Maybe differences in hardware, internet service, upsampling in Roon, gain within the streaming software, data centers, etc. are playing a part?
Tidal or Qobuz
Many say Qobuz sounds better than Tidal, not Jay.
