No offense meant to anybody so don’t be hating on me now ....and apologies for veering a bit of topic. Us old pharts do that.

I would love to see a correctly done (good research design) double blind study that tested for discrimination accuracy of those tested regarding:

High quality mp3 vs wav vs etc.
Vinyl vs CD vs the best streaming platform
$3K speakers vs $500 speakers
High end tube amp vs a decent sold state amp

And more... smile

Good article. I'm surprised CD sales are still that high.

Caveat 1: I have a huge vinyl collection dating to early Elvis...including the Beatles "Butcher" album - got real lucky with that! All purchased when released. After the advent of CD's they were all relegated to the basement where they remain. smile I've gone from that vinyl collection to replacing most with CD's to uploading 500 CD's to iTunes to Apple Music.

Caveat 2: I owned some of the best turntables and tube amps. Mostly they too reside in the basement...well I wish all the tube amps did given the market for them now!
