A long time ago I read a couple of different articles about differences in dynamic range as well as separation and after that I gave up.
The variability in mastering, not just from LP to CD or SACD but from release to release was so great. Some tests showed CD's having markedly reduced separation, or SACD being deliberately manipulated. It is possible that benefits to LPs today are in the hands of the ME's. Maybe they know the vinyl lover is pursuing a different sound than the MP3 downloader?
At best, I think we could tell there was a trend with mastering engineers to get as loud as possible when CD’s hit. We’ve barely recovered from that in pop culture music.
By all means, play what you enjoy!
