Picked up a few LP's yesterday, at 25 cents a pop. First played was a quad-compatible "Also Sprach Zarathustra," from 1975. It had lots of pops, but a good performance, and the LP didn't look all that bad. Then I put on "Switched-On Bach," bar-coded and ID's as a "Wendy" not a "Walter," so it wasn't an early copy. It was superb! No pops, no crackle, no snap, just music. Wonderful! Then I was trying to clean some other LP, and finally took it to the kitchen sink, and washed it with dish soap and water. My Audio Cleanica does have its limits. Washing made a big difference, but I haven't played it yet. The label came out fine, too. If you haven't tried the method yet, do it with some no-account LP for practice.
