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.

the only problem with the whole 'minimal crosstalk' approach (which i have used) is that it's only close to optimal. i have found that i can eyeball azimuth typically as close as when i measure minimal crosstalk.

dead on azimuth is where the phase is aligned, not gain. the image snaps in based on phase being equal in each channel.

i suppose that the Fozgometer must somehow measure phase.

i have the new Talea tonearm with dynamically adjustable azimuth. i know of no other arm which allows one to adjust azimuth while listening. i watched the arm designer use this to dial in azimuth and it really works.

Lew,

Joel Durand, of Talea Tonearms, set up my Talea in my room. he used an Ella Fitzgerald mono Lp to make the dynamic adjustments to the azimuth. i can tell you that it took our 'eyeball' azimuth set-up to another level.

regarding the Fieckert software; Michael Fremer has done a seminar with Dr. Feickert at RMAF the last 2 years that i have attended. he showed graphs of how this software shows how the best crosstalk position compares with the best phase angle position with azimuth. it would be a coincidence if they happened to be the same.
