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.

Slaw; excellent post! Those are my thoughts on the matter as well. Easily repeatable settings. Fine tuning may be worth the effort but if you can get to the same reference point each time with a minimum of time and effort, it's worth it's weight in titanium.

Madfloyd: You will probably have to wait like the rest of us. It appears that the demand for the Fozgometer is still outpacing the supply. But the wait time should be far less than it was a month ago. Order up and it will arrive in due time. :-)

Dan: Nice! The Talea is a unique tone arm. It would be great if more tone arm designers and manufacturers began treating arm height and azimuth adjustments with the same importance as they do tracking force (counterweight) adjustments. With so many tone arms, arm height and/or azimuth adjustments are either lacking entirely or crudely implemented. On-the-fly adjustments may not be a priority but at least they should be easy and fairly quick adjustments.

I still think the Fozgometer offers a good starting point (an easily repeatable reference) for fine-tuning azimuth adjustment, even for tone arms like the Talea.

Hi, Mauidj; the Fozgometer also uses a record and test tones to measure crosstalk and determine any adjustments needed to correct azimuth.

Brad, thanks for the post. The Fozgometer is being criticized by people that have never used it to set azimuth. And the complaints by people that have used it may or may not be related to how well the Fozgometer functions. I get the impression that 1) there may be cartridges that are at the limits of "acceptable tolerances" that are causing problems, 2) there MAY be some Fozgometers with quality control problems, and 3) some people may not be using the Fozgometer properly.

I agree with Lew that the documentation about, and the user guide for, the Fozgometer is minimal (probably intentional) and so speculation and the possiblity of user error is elevated.

Regards,
Tom
