Frankly I am a bit surprised that the three main players manufacturing cantilever/stylus assemblies even bother to do so anymore. This is a small market. But yes the manufacturer must grade the parts. Doesn't mean those slightly off need get trashed. Just that the top carts need the perfect ones. Seems obvious no?

Just to make this terminology a bit more complex, I was once informed that the azimuth adjustment on a triplanar tonearm is flawed, because as you alter azimuth you are also altering zenith. So, I thought about how the triplanar azimuth adjustment works as I tried to understand “zenith”. TheTriplanar allows you to twist the arm tube back at the pivot point. With that information, I thought of an analogy with a light plane landing on a airstrip. If you watch airplanes, you can see that when they get caught by a gust of wind the tail section can sometimes lean to the left or right and down, with respect to the direction of the plane. That seems like what would happen to the stylus when adjusting azimuth with the triplanar tonearm, because of headshell offset angle. So I thought that was zenith, with respect to a phonograph cartridge. It’s an aircraft analogy I think. Pilots talk about “zenith”.

@lewm, that is called "crabbing." The airplane is flying on a vector to counter the wind. They actually crab at altitude also, whenever there is a cross wind. My brother is a pilot. In his Cessna you can feel it in the seat of your pants just like when you kick the a-s of your 911 out:-)  Zenith is straight up and the stylus is twisted on that axis like a plane crabbing. Twisted on it's zenith? Whatever.
The Schroder CB adjusts azimuth the same way. I like Soundsmith's solution. You have 3 stiff rubber logs that fit into slots in top of the cartridge. You can compress one side more than the other changing azimuth maybe a couple of degrees. I have not tried it yet as I still do not have a turntable. I'll report on it when I do.
@cleeds, You have to give pindac the benefit of the doubt. There is a language barrier as with rauliruegas. He means well.
