I have Spotify Premium and Tidal Hifi with Roon. Qobuz is not available in my country. My DAC is Musician Pegasus. 

Spotify Premium sounds more compressed and slightly grainy when the music gets loud and busy. 

Tidal Hifi with Roon sounds more spacious and cleaner. 

Spotify Premium sounds better when I am using my TWS, Tidal/Roon sounds better when I am using my main speaker setup. 

I tried using DSP Upsampling in Roon. All the PCM and DSD upsampling options come at the cost of loss of details, smaller dynamics range, and more 'digital' sound so I keep it off. I actually like the MQA tracks, they seem to have better dynamics compared to non MQA ones. 

Interesting responses thanks.  I feel Qobuz definitely a bit better; most do. But I still value selections on Tidal which are not available on Qobuz.  

Great info on this topic. I use Bluesound with Tidal as my service, but this has made me interested in perhaps a trial of Qobuz... I've built up quite a collection of "favorites" in Tidal which I would hate to rebuild on another service. On the Qobuz site it says:

Yes, you can import your playlists created on other streaming platforms thanks to the Soundiiz tool.

When you click the link it takes you to a page in French, with no option for English. Can anyone relate their knowledge or experience with particular optionality? 

There is info on Qobuz and Soundiiz along with tutorials here.

I have extensive playlists that I made in the pre-streaming era. I tried Soundiiz to export to Qobuz, but it really didn't work well and I gave up on Soundiiz.

Infuriated by MQA two years ago, I switched to Qobuz from Tidal and never looked back. Agree that Apple sounds better than it's given credit for, and anyhow my old iTunes/Apple Music playlist can never be replicated. But that plays only on my backup system. Some rainy day (or pixie dust day, which seems no less likely) I'll get around to loading that playlist into Aurender for comparison with Qobuz and good streaming radio sources.
