Qobuz.

Here’s an honest review from someone with an MQA DAC.  I’m currently using an Aurender A10 (which I purchased in order to stream MQA tidal files).  I would like to believe that I have decent equipment that could showcase the potential differences (McIntosh preamp, 601 monoblocks, and Amati Futura speakers).  I’ve been A/B’ing the Tidal MQA files against the comparable Hi-Res files and will say that they are very close to identical for me.  Here’s what it boils down to:

Tidal - $5 cheaper/month, even though MQA is lossy - it sounds identical (to me) to the uncompressed Hi-res files from Qobuz.  The downside is that you have to have an MQA DAC to get the full potential from MQA.  

Qobuz - The biggest plus for Qobuz is that you do NOT need a specific DAC to recognize the potential of Hi-Res and It sounds ohhhh so sweet! Did I mention that they have Springsteen in Hi-Res?  I’ve been quite impressed with their Hi-Res catalog. 

If you have an MQA DAC, you will be just fine with Tidal.  If not, I would recommend Qobuz.  When all is said and done I will probably stay with  Qobuz due to the fact that I prefer their Hi-Res catalog and like the fact that I can purchase the music from them as well.

Just started my trial today.  Compared to the last time I perused Tidal, there seems to be a lot more Classical available, not to mention better organized 

beetlemania I just clicked on a random album in the Quobuz store Mini Mansions.....A Guy Walks Into a Bar and the CD version $12.99 hi-rez $14.99 but hi-rez with the sublime streaming package $7.49. Quite a nice savings! The Sublime Tier is $299.99 per year. It's basically the same monthly rate at the Studio tier $24.99/month but you pay upfront.

@jond Thanks. I plan to try it soon, probably go with the sublime package.

I have both Tidal and Qobuz at the moment. 

Comparing 24/96 Qobuz and Tidal MQA unfolded to 24/96, both sound good but different. For certain tracks, vocals seem to have more body and are more present on Tidal than Qobuz. For certain tracks, Qobuz seems to have a wider soundstage and better at micro details. On balance, I slightly prefer the sound quality of Tidal. 

At this point, I might stick with Tidal since I find the interface more intuitive (probably since I've been using it longer and prefer the black background) and music selection better aligns with mine. It's not a strong preference and I could be convinced either way. I do find the option of not having to get an MQA DAC a very big plus for Qobuz.
