A, men sikter vel så mye langs pickup huset. Etterpå finjustering vha ørene.
mvh
Forsikre deg da om at nålefana står helt rett i huset.
Hvis det ikke blir ca. riktig med å sikte etter pickup huset, enten med toppen parallell med platen/speilet, eller med sidene helt symmetrisk (ca. rett vinkel - litt avhengig av konstruksjon) i forhold til platen/speilet, er det mest sannsynlig noe feil med pickup'en som ikke uten videre kan rettes opp med justering.
Uansett må den siste fin justeringen gjøres med ørene -
stoler dere virkelig mer på øynene (eller målinger! 
) enn ørene?
Juster i meget små steg til lyden "sitter" (bedre 3D og imaging, mindre sibilans og mer behagelig i de høye frekvenser er min erfaring - damestemmer er ok å bruke)

I am a proponent of using your ears rather than instrumentation for adjusting azimuth. There seems to be a lot of angst about getting this adjustment "right". I assert that "right" is when it sounds best, regardless of what the technical parameters may be. I suspect that in most but not all cases an instrument guided alignment will also deliver the best sound. But since the only thing that matters is the sound, why take the detour into instrumentation.
With good line contact stylus it is very easy to hear when azimuth is properly adjusted. For most people I think it is quite unlikely that using an instrument will result better sound. And there is a distinct possibility that an instrument alignment could produce worse sound.
Some cartridges are considerably less sensitive to exact azimuth and VTA adjustment. Instrumentation does make adjustment easier in this case, but what does it accomplish other than to ease audio neurosis? If you have a cartridge where you can not hear the difference between close and exact then exact adjustment buys you exactly nothing.
Oh, yes and our ears are free"

Doug,
Congratulations on advancing to "adjusting by listening", and on learning to hear the difference azimuth adjustment makes.
Like Teres I used to use electronic equipment to adjust azimuth. After sessions with several cartridges I realized I could adjust just as accurately while listening to music, not to mention faster and with less fuss. You described EXACTLY what to listen for, IME.
Good that you discovered levelling the headshell doesn't help much. No one plays grooves with a headshell, we play them with a stylus and few styli are vertical to the necessary degree of accuracy. Levelling the headshell's usually a time-wasting distraction. Roughing in by eye is best done by making the stylus look vertical with a mirror and magnifier. After that the fine tuning is by ear and the headshell ends up wherever it ends up.
VTF, VTA/SRA and antiskating are also all best adjusted by listening to music. The more practiced we get the fewer measurements and test records we need.
Good post,
Doug
P.S. Hiho is correct. I described his observation by analogy many years ago on VA. Azimuth changes with vertical arm angle on any tonearm with an offset headshell. It's unavoidable."
-------------------------------------------------
Jeg vet ikke om denne stemmer - med tangentialarm er denne problemstillingen ikke relevant - men kanskje det er riktig? I så fall kan det kanskje forklare noen av rapportene fra brukere om stor sensitivitet til VTA forandringer - siden de også fører til endring i azimuth. Eller?
mvh
