rotaries
If the azimuth cannot be fixed by the limited headshell adjustment, you really need to return the cart you bought, you have a cartridge problem not a tonearm problem.
The headshell provides more than enough adjustment. Unfortunately the difficulty and time it takes to merely come close to the accuracy of the Well Tempered tonearm as determined by the Fozgometer is laughable.
On the other hand if one doesn't notice the difference in azimuth then close is good enough.
