Dear @deadhead1000 : "" I know I shouldn’t let it bother me, but it does and it has impacted my enjoyment. """
More than affect your or my opinion always is learning time and we can take advantage of that kind of opinion and how can we take advantage?: asking that gentleman if that " piercing " appeared in all LP tracks and in all kind of MUSIC both of you were listening it. I think you still can ask about.
In the other side and opinion of my room/system reproduction makes me , at least, to make a check up at each single link i the room/system chain and spcially to the cartridge/tonearm/TT set up and even if is ok I will mount again the cartridge to do a " freshly " set up and when I unmount the cartridge I will try to see it stylus tip/cantilever through a microscope.
Now and it does not matters the cartridge " pedigree " all new cartridges needs play hours to settle down and after those play hours we should to make a new check up tonearm/cartridge set up. Normally after settle down we have to " play " with minimal changes on VTF and/or VTA/AZ.
Always we learn a lot from " bad " criticas/opinions that the other way around opinions. A good audio friend is the one that tell you what he is listening no matter what.
Regards and enjoy the MUSIC NOT DISTORTIONS,
