Purchased a 30th anniversary LP of Dark Side of the Moon on a half speed mastered, 180 gram, special formulated virgin vinyl. Already had the same album on CD. Played both synchronized together and switched back & forth between them. There was no doubt the vinyl was superior. It won hands down on overall sound quality. From that point forward I replaced all my old records with 180 & 200 gram virgin vinyl recordings, many are 1/2 speed mastered, which I believe have superior sound quality.
When and how did you, if at all, realize vinyl is better?
Of course I know my own story, so I'm more curious about yours. You can be as succinct as two bullets or write a tome.
