I’ve added Quobuz this weekend, I already had Tidal.
I’m still evaluating if I can find all the music I want in Quobuz as well but for now it seems I can find it in both. (Europe)
I plan to ditch Tidal as it only has CD quality and I don’t use lossy MQA. I disabled MQA in the Tidal app by setting it hifi and in Roon by setting MQA Core decoding to off in the DAC preferences. I seem to get the CD quality streams then. I normally don’t use the app, only the IOS app in the car and on the motorbike.
I really like Quobuz: quite a bit of true hi-res albums and the ability to purchase them at a big price reduction with the Sublime+ plan I chose. I use the Mac app to find music to purchase since that doesn’t seem to be possible from within Roon and the IOS app for the car and bike like I did with Tidal.
So for now I have both and if I will ditch one it ‘ll be Tidal.
