As you said your records are pre-1979, and this is true analog recodrings. It was the era when mastering and pressing was on the highest level, Japanese pressing of the same releases normally even better. Listen to your favorite music just like it was recorded, mastered and approved by the artists when it came out on vinyl. Very few reissues can sound better than this, if you don’t want to hear something overcompressed, digitally remastered today by strangers (not related to the band) and reissued by someone who just bought copyright. Rember, musicians from the 60’s - 70’s era are old today and they are happy if someone reissue their music in any format, they don’t care much and can’t control the whole process anyway. There is a huge difference between audiophile reissues and normal reissues. 180g press is not an indication of the better quality at all. But even if an audiophile reissue is from the master tape, don’t forget that tape is over 40 y.o. today (not fresh).
Most of my collection is music from the 70’s (original vinyl). I don’t like the quality of reissues sonically.
