Or your records; or a combination of the TT and the records... How does the "scraping sound" sound? Can you post a file? Have you checked to make sure the needle is seated properly and the cartridge isn't scraping the record itself? Are you weighting it with something (nickels, dimes, a quarter)? Remove the weights...
Which model Vestax? Is it the portable? I have the Numark portable, just as a 2nd/3rd TT and for auditioning stuff in the library. It's actually a decent little portable TT, but I probably would want something more hi-fi for sampling/production, and even vinyl transfers to CD (which I do a fair amount of, so I do use a Technics in the studio).
If the scraping sound is happening on everything you play, you might have a serious issue there.
