You’re right about vinyl quality. For the brief time I toyed with vinyl again a few years ago I was appalled at the quality of some of the offerings. Surface noise in some cases was obvious, meaning they’re using low-grade regrind material, as well as just plain bad masterings. I won’t get into the pricing lol.
Not sure you’re aware, but there are a few websites for researching recordings and their quality. I often use Discogs, DR Database, and Hoffman Music Corner for this purpose. And AllMusic for music quality. Not for everything, but definitely worth checking out if you haven’t already.
