I had my dealer set up my Aries 3 when I bought it, but being the tinkerer I am, I decided to get the proper tools to do this myself. When I initially got the table I checked and redid the azimuth and VTF. I then ordered the Feickert NG gauge, Fozgometer and the AP Ultimate test LP. I set my overhang to the Baerwald setting, adjusted the cartridge so cantilever is perpendicular to the null pt., and then checked the azimuth with the Foz. only 0.5db difference between left and right (left being higher); I left it alone. I am now awaiting the arrival of my Manley Chinook phono stage. Santa has been nice to me this year.
