I've been disappointed with some of the vinyl I've picked up and played, sure. But there have been some outstanding ones, and those are more memorable than the bad ones. So here are a few of my favorite great pressing that I enjoy:
I read the one post about Joshua Tree, I'll disagree with that one. I'm responding from work, so don't have the album in front of me, but my copy is stellar, and a joy to listen to.
Another GREAT copy IMO is Boston's First Album; my copy has an orange label, and I believe was engineered by Bob Ludwig. The sound quality is remarkable.
One more good one: Bad Company, the first / self titled album, so good.
