Optimizing phase and crosstalk by adjusting azimuth is best done with measurement software.

@nekoaudio adjusting azimuth with a test disc and software is certainly best way to adjust THAT specific test disc to the stylus.

The problem is that if we take 12 different pressings/brands of test discs then they all varying from each other. That variance is also between all of your albums on our collections.

The reason is that the cutting head in the lathe machine have of course also azimuth variance.

So the best way in my humble opinion is to put the azimuth as vertical as possible and that will then in average be the best "compromise". Because of the variance between all the different albums will give the best setup on average for all the discs in our collections.

So  adjusting azimuth with software/fuzometer/oscilloscope and one test disc is in my opinion a waste of time and resources.

@optimize well from my experience a bunch of records went anywhere from slightly blurry or an outright sonic mess to focused enjoyable music, after matching phase across two channels using software. So I will continue to recommend it. Especially as the stylus alignment may not exactly match the internal alignment.

@nekoaudio good to hear! Thanks for the feedback.

Normally I would ascribe to the 1950
”
rebuild your own transmission “ philosophy but nobody asked the OP about a variety of skills and yes physical acuity needed to wring the best out of a TT setup.

so have it done, learn if you can and or to your comfort level and ability and move on...

hoping the OP enjoys the music !
