One reason I hate the N78S stylus from Shure is that it won't take any added
pressure and will not play any record with the slightest warp. It's also
incredibly delicate..I managed to twist one while simply cuing a disc that had
a groove defect or a bit of tape over a cracked edge. It's good for some discs
that otherwise mistrack but nowhere as adaptable as the S78E or the Stanton 2.1
TE (the Stanton, not the after market replacement that Expert makes, which is
also useless for 99% of my needs).

If the stylus mounting is riding too low and the label is the slightest bit curled up it will make contact with the cartridge and you'll get a thump or the cartridge will completely mistrack. In these cases I usually resort to gluing the label back down or easing up on the stylus weight for the last few revolutions and then editing in software.

It was more of a hollow scraping sound that could partially be alleviated by wet playing and even more by summing to mono in the final mix. Finally I believe I've found the culprit and solved the problem.
