A nice person on this forum sent me an SP14 for testing purposes, as seen on the pictures.
The problem is that there is a constant faint but audible "grating", "scraping" noise (both L and R), especially obvious on lead-in grooves and silent musical passages... which is a shame because the cartridge tracks very well. Even the end of side distortion seems absent!
I can't make a close-up of the tip, but there is a rondel and the tip (black in colour) is attached to this rondel.
It does seem to excite the arm resonance, because it is the same frequency as the arm when you touch it.
Any ideas?
Edit: an o-ring around the cartridge body attenuates this noise strongly... Knackered stylus?
Look at the amazing condition of this SP!
