Listening to John Coltrane’s magnificent mono Prestige ‘58 recordings on vinyl reissued recently in a lovely box set. Why oh why is it the case that every time I play mono vinyl on my restored Garrard 301 table with Miyajima Zero infinity cartridge, it blows away every fancy DAC I have in my house including the Lampizator Pacific, the Mola Mola, the Chord Dave et al. Have we advanced at all in high end since the days of mono vinyl? A puzzle. But I’m enjoying it all the same. My right brain tells my left brain to shut up and enjoy the sound of mono vinyl.

I have the CD version of that box set, and only half of the sessions are mono (track 1 to 15 - "Big Paul"). I believe that is the case for the LP version as well. Regardless - great music! The CD version sounds good, but of course YMMV depending on your system.
To determine if a track is mono or stereo, I use my ears, but also scan all my files and calculate the difference between left and right channel (with FFMPEG), and have the result updated in my tags.
In this session, the average difference is < -100db (numbers in brackets), so that's mono:
Perfect mono would be 999, but there is practically always a small difference between the two channels.
In this session, it's stereo:
It is odd that they did not issue the mono version of that session since it was originally released in mono:
Perhaps the mono tapes were not in good condition? These early stereo recordings often have too much left-right panning of the instruments, they are not as pleasant as the mono versions - even more so if you listen with headphones. On this particular session, however, Coltrane's saxophone is centered, so that's nice. I would be curious to hear the original mono LP, but they are quite expensive, especially if you want a "Mint" copy.
My understanding is that any mono LP issued after 1968 was made with a stereo groove, so can (should?) be played with a stereo cartridge.
Lately I have become interested in the history of mono vinyl. I've done quite a bit of armchair research the last few days, and I have compiled a list...
