chakster, There were major differences in quality between the genres. Motown made the worse pressings ever. Rock and Jazz are hit and miss.
It has nothing to do with the genre, it depends on the pressing pant, mastering of each release and country/region where it was pressed. It is also depends on the recording itself, because not every band can make a proper recording.
Japanese pressing from the 70s (from the original master tapes) is the best for all genres.
Classical was handily the best.
I don’t listen to classical music and i’m not into rock music.
Fortunately, those us with turntables have become a lot more discriminating and are willing to pay for top notch pressings. Records are now better than ever.
Reissues are not better at all, in 99% they are worst ever, because they are digitally remastered, if you’re lucky they are made from an old master tapes. But comparing to the best original (vintage) pressing those reissues are very bad (most of them).
I don’t care about new records, as the OP i collect vintage vinyl, mainly from the 70’s.
When someone looking for turntable, speaker, phono stage, cartridges it is for all genres of music. The rest is personal preferences and just speculations.
