I have recently signed up for trials of Qobuz, Tidal, and Deezer (already using Amazon Music Unlimited). I stream via a Bluesound Node to a Roksan Caspian amp and PMC speakers - so a reasonably high/medium quality setup. Frankly, I can not discern any material difference in quality between the four and do not hear any improvement from hires.

Having researched the subject further, science suggests that the human ear is incapable of hearing hires. Perhaps it's just me and my older ears.
