Beerdraft,
Any update to your problem? From reading your initial post, your screathing noise that you describe when listening to Norah Jones (Come away with me) vinyl record sounds similar to my problem. It sounds like the record is messed up at those particular spots. For me the first song on Side A, has that annoying screeching sound that lasts like one second or so near the beginning. It also happens on track 7 on Side A when she sings a high note. I got the 200 gram version of the Norah Jones, do you have the same record? I think this record was mastered/recorded very poorly(with this screeching sound flaw) on to the vinyl during production, cause I only seem to have this problem with this record ONLY. I think there might have been a bad batch of records made from Classic Records. Just to rule out that the record might be dirty(which it isn't cause I just bought it), even after cleaning it, the same spots on the track have that annoying screech sound. Based on that, I think the problem lies with the record, not your setup. Try bringing that Norah Jones record to your dealer and play it on his vinyl rig(assuming his table is set up correctly) and if you hear these same screeching sounds, it's the record.
Good luck !
