Setup may be your problem.
I have read that it is not correct to equalize crosstalk, especially for premium cartridges. If memory serves, SoundSmith writes most convincingly of this. I set up optically, then use a well modulated (loud) NM record that distorts on one channel, and adjust until the distortion goes away. Then I listen for distortion on the other channell.
I also get precise about mounting torque. I use a German torque screwdriver.
