So here's a vinyl noob question of note -- why are some records so much noisier than others? This morning I listened to a couple of mid-80s LPs that had clearly been knocked about a bit in their lives, but after cleaning were very quiet and generally pleasureable to hear. Then I put on a brand-new "special edition" 180g release that supposedly got the kid glove treatment in both production and pressing, yet it's like the needle's tracking over sandpaper. The surface noise is so high it's pretty much unlistenable.
