I have a Spotify account for my wife (iPad) and a Tidal account for me and my audio system (Windows 10, USB connection to the DAC).
For my Tidal listening, I prefer to download and install their app, instead of using the browser version, one less set of "variables". I have found the performance and SQ from Tidal to be awesome.
From what I’m reading, it sounds like sometime soon Tidal will be offering MQA, at first thru their app, later thru the browser version. I hope that they will be doing the conversion from MQA to whatever will be accepted by my DAC in the app, and not require that we purchase new "MQA-capable" DACs to enjoy the improvement in SQ. Time will tell.
