UPDATE 31Mar19
I trialed Qobuz and got very few hits on some desired artists - mainstream ones are OK but others, not so much. I also streamed their hi-res stuff which only amounts to the most recent releases and then it mostly means just CD quality (16 bit / 44.1KHz). On rare occasions 96KHz or very rarely 192KHz are available but wholly insufficiently to warrant subscription - meh; I cancelled. Here's their UI playing Jenny Lewis's latest drop in CD quality... I think that's the maximum quality available from the web player. The second image shows their native app actually playing the same track at better quality (24bit / 48KHz), and it was better.
