I recently switched from Tidal to Quobuz and I don't think I'll ever go back to Tidal. Tidal was decent but it kept having technical issues for me and the last issue in combination of a certain person buying Tidal was the last straw. When I switched, I noticed that the sound quality was better on the majority of the things I listened to. I was not expecting that.
I was also not expecting their library to be as expansive as it is. This may not have been the case when this thread was started but I really see no difference in selection(s). Some genre's have more, some less.....with both Tidal and Quobuz.
Given that the sound quality is noticeably better with Quobuz and at a lower price than the Tidal subscription I had, I don't think at this point I will ever look back.
Typically, I am not a subscriber to "convenience" formats but I do use this while in the office (a couple of rooms away) during business hours when I am working from home. It is nice to be able to listen to the rig at any given volume level, switch songs and mute the system when a phone call comes in....all from the computer at the office. While I still won't typically sit down in the sweet spot and listen to the network player, the sound quality improvement (especially on certain tracks/albums)? It does bring me one step closer to the sonic signature of physical media, sound wise over Tidal.
