If you have a record with left channel only tones and right channel only tones you can record these with something like Audacity and adjust azimuth until you reduce crosstalk (relative level of the "silent" vs. non-silent channel for left and right) as much as possible. Obviously a more tedious procedure than having a gizmo like the Fosgometer, especially on my SME 309 where the azimuth adjustment is achieved by twisting the replaceable headshell.
Azimuth and the Fozgometer
Finally received the Fozgometer after a 2 month backorder. In the past I have always used a loupe and a front surface mirror to set the azimuth on my Tri-Planar with Dynavector XV-1S cartridge. According to the meter, I was very close to a correct azimuth. I wasn't prepared for the effects that a very slight adjustment would make. Nailing the azimuth has brought my soundstage into tight focus. I have never experienced this kind of solid imaging in my system.
I know that the $250 price tag is a bit steep for something that won't get a lot of use, but this is not a subtle improvement. There are other ways of measuring azimuth, that I am not very familiar with, but I would doubt that they are as easy to use as the Fozgometer.
