One area of vinyl folklore is that "First Pressings" are better than later ones because:However, there may well be historical cases where LP production master EQ moves improved on poor mixdown tape EQ choices....
1. The sleeve is often "embossed" or otherwise embellished while later pressing are not. Also the original pressing sometimes included a poster that was not in later pressings. This is actually true and easily verified.
2. The original pressing is mastered by a "famous" mastering engineer like Robert Ludwig or Rudy Van Gelder with a "signed / initialed" dead wax while later pressing were mastered by junior engineers. This is true to the point that originals often have a signed dead wax and later pressing don't but in my experience it is "hit or miss" if one really sounds better than another although sometimes they do. Given a choice I always like knowing the mastering was done by a "master" rather than an intern.
3. The original pressings were made with "virgin" vinyl while later pressing used "regrind" in the vinyl formulation making them noisier. This was especially an issue during the 1970's "Oil Crisis" when vinyl prices went through the roof. This is one piece of folklore I have no idea about. I can't say I have any direct experience with a quiet first pressing and noisy later pressing because of the vinyl used but some people go as far as to say some 1970's vinyl has visible pieces of paper from a reground label in them. I would be curious if there is any truth to different vinyl being on first pressings.
All things being equal none of these things would make an LP sound better than digital but they could make one LP sound better than another LP and in some cases due to either a great LP mastering or poor digital mastering or lost of damaged master tapes some people may prefer the LP version. All these weird variable are also part of the "fun" of LP's.... digital is digital for the most part which is great but LP's have much more variability so there is the "treasure hunt" aspect of finding a preferred version of your favorite old music that is not on the streaming services.
