>>>>listening digital files from which 90% of new vinyl releases are cut.<<<<
I'm trying to stay out of this because, y'know... And, I am probably as "vinylie" as the next guy; maybe more so. But I still like CD's and I have an iPod and an iPhone (and other digital players) as well.
The truth of the statement above is unfortunately without question, when it comes to _new_ productions that come out in multiple formats. They often do not bother to make multiple mixes and masters anymore, consequently the vinyl is often made from the same mixes that the MP3's (and CD's if there are any) are made from. So there is no optimization for each format. The vinyl is pressed as an after-thought. Because it's "cool" and Taylor Swift wants her friends to be able to get copies on vinyl (that they can leave unopened).
Not true for reissues that have access to master tapes of unreleased mono masters/alternate takes, of course. Also not true for vinyl-centric labels like Daptone, Colemine, and others.
