Dear Nolitan: In a pivot tonearm you can't eliminate 100%. If you want minimum distortion at inner grooves then align your cartridge/tonearm with Stevenson geometry.
If after that you still heard that IGD then maybe the tonearm or the cartridge or both are out of specs or are not a good match between them.
Regards and enjoy the music,
Raul.
