Dear Stringreen: Some tonearms comes ready for the offset angle if you mount it according the manufacturer advise but if you want to change it then sometimes you need to twuist the cartridge to have the right offset angle.
MANY TIMES YOU HAVE TO DO IT BECAUSE YOU NEED THAT THE CARTRIDGE CANTILEVER BE STRAIGHT TO THE PROTRACTOR LINES WHERE SEVERAL TIMES THE CARTRIDGE CANTILEVER IS A LITTLE OFF POSITION WHEN BUILDED BY THE CARTRIDGE MANUFACTURER.
The tonearm/cartridge set up is a extremly critical set up where there is no " land " to even minimum errors/mistakes because fraction of mm. change for the worst the distortions levels and where those distortions happen.
I posted here that for the same cartridge/tonearm set up the difference between Löfgren and Baerwald alignment is less tha0.5mm on overhang staying the offset angle almost the same and if you go to the links I posted you will see in the charts how changes the distortions for both aslignments.
This kind set up permits CERO tolerances if we want minimum distortions. CERO tolerances is almost imposible to achieve so we have to have extremly care to make this kind of set up everywhere in the " circuit of the set up ".
Regards and enjoy the music,
