fozgometer v2

Please correct me if I’m wrong. I’m sure the foz works as advertised to equalize crosstalk. But what I and others have said is that in doing so, the stylus tip in many cases will end up slightly askew with respect to the groove, unless the coils and magnets inside were perfectly aligned at the factory. But if the cartridge is perfectly constructed, then you don’t need the foz. Just aligning the stylus with the groove walls will give you equalized crosstalk. 

Do you really anticipate that you’ll only align one cartridge for the rest of your life? Anyway, in my opinion you don’t need a fozgometer. Just set azimuth so the stylus tip sits symmetrical to the groove walls, which almost always means set azimuth at 90 degrees. This you can do with a mirror. The obsession with equalizing cross talk between channels, usually results in setting the stylus tip at an angle to the groove, which in the long run results in aberrant stylus wear and early demise of the stylus
