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.

This is just a stab at the question: To set azimuth with my Signet, you first have to set the meter to 0 db for the channel that directly receives the signal from the test LP, so you can then measure the crosstalk in the opposite channel. When you do that in both directions, you have to have balanced the signal each time in that way in order to compare the crosstalk numbers (which are in terms of negative db, down from the 0 db reference). Perhaps that is what is going on with the Foz.
I admit I'm not as versed on these issues as you all seem to be. Having said that, here are a few remarks...

Adjusting azimuth by eye... That seems to be the preferred and less expensive method. My issue is, why is so much written about proper cartridge, tonearm, TT adjustment and their importance, but somehow azimuth adjustment is OK by eye? Just recently MF from Stereophile had a comprehensive article on STA, (stylus rake angle) and just 2 degrees off of the standard 90 degrees makes all the difference in the world. So my point is, if this is true, should we just use our eyes for azimuth as definative setup tool. As my system has gotten more resolute through the years, any "slight" changes are extremely more noticable. Therefore, why is it not acceptable to use a $250.00 device that will take one often thought about equation out of mind, so as to explore other issues?
Isn't it better to be able to rule out one importantant aspect of cartridge allignment so other sensitive issues can be addressed? Example: Tom Port tried to get me to not spend "big bucks :on a VTF meter, saying you can do it by ear. Well, yeah!. But who wants to start at a far off place only to find later that their search could have been made so much easier with a quality scale?

If you want to be Daniel Boone, go ahead, My time is impotant to me and worth a lot of money.

II'd rather spend the bucks on a quality device that will get me in the right direction. This will also allow me to check any variations I migjht suspect rather than fretting over what might be!
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.
