This editorial comes across as a bit condescending, and considering the likely audience of audiophiles, more than a little self-congratulatory. I don’t think anyone is questioning that “good gear sounds better”, although there is very definitely a point of diminishing return and a lot of snake oil out there. It’s also reasonably clear that people can tell the difference between heavily compressed MP3 and better files. It’s not at all clear, though, from scientifically conducted, blinded A/B studies, that the overwhelming majority of people can tell “CD quality” from high-res files. I can only speak to my own experience- I have decent gear, appreciate the difference between my best system and the others, but am almost entirely unable to tell the difference between Apple Music streamed over AirPlay 2 and the “high-resolution” files I get from a hardwired connection.
(Sorry for the bold type- not sure what I did)
