Try examining the needle, head on, with a magnifier to see if it appears perpendicular to the cartridge base and/or headshell top. If not, I believe you need to adjust azimuth until the needle is perpendicular to the record/platter surface. Adjusting the cartridge base and/or headshell top in this case would not result in the proper azimuth.
I have noticed needles that are not set properly in the cantilever by up to several degrees and this can make a discernable difference in the quality of the sound. The relationship of the needle to the record in azimuth and SRA is everything.
