fourwinds, with regard to your question of 04/06, I am not clear what you actually did. I had suggested aligning the cartridge for zero azimuth by eye only, ignoring the Foz reading. You could use a mirror or whatever sort of aid might help in that. Some people put a small bubble type level on top of the headshell when adjusting for zero azimuth or is it 90 degrees of azimuth? I hope you know what I mean, top of headshell parallel to the LP surface when viewed from the front. (My computer changed to italics for no apparent reason here.)
As to whether the Foz is reading cartridge output per channel or crosstalk, I have no idea, since I have never even seen a Foz. As Terry wrote, there are two schools of thought regarding crosstalk/azimuth. Some recommend adjusting for equal crosstalk, which means that the amount of R channel signal appearing in the L channel would be the same as the amount of L channel signal appearing in the R channel (measured in negative dB). Others recommend just minimizing crosstalk. When you do the latter as a goal, the amount of crosstalk will usually NOT be equal in one channel vs the other. I don't think there is any right or wrong in that regard.
So, have you set azimuth to 0 or 90 (whatever) without any regard for the Foz, and what did that do to your soundstage width?
