I have read the articles on MQA but Tidal sounds good to me and my non-mqa dac shows 96k which is pretty high resution. The Doge 7 dac I use makes more difference in sound then getting the full unfold on my node's MQA dac. As far as provenance its not too hard to tell for many artists that my cd is same mix as the one online because there is only one mix.(ex. Van Hunt debut cd)
I do curate my cd collection and seek out the best mixes when there have been multiple issues over the years. Some hi res remasters are really good as aging rockstars finally dust off the true original masters and put out their best sounding cataloug yet uncompressed in hi res glory (led Zep comes to mind). Don't like licensing schemes but can't argue with great sound. Tidal or Quobuz through a good dac can be very engaging and indistinguishable from a transport playing the cd through the same dac when doing A,B comparisons in my experince
