By the end of the week I'll be thru my month's trial of Qobuz and will need to decide if I'll buy a membership. I'm leaning to do so and to also keep my Tidal account as well.
I do enjoy many (but not all of the) MQA masters on Tidal. If there's anything that doesn't sound "right" to me, it's that many of them seem to have accentuated the bass.
When I've compared the sound of "regular" CD quality albums, Tidal vs. Qobuz, using the same Windows machine, same USB connection to the same DAC, the only difference is the Tidal vs. Qobuz app to do the playback, I must say I believe that the sound quality on Qobuz is slightly superior (i.e. a little better clarity, sound stage, stereo image), not a "day and night" difference, but it does seem to be better with Qobuz.
