Cartridge Opinions - Sorry

@mijostyn : Yes, I posted that because what you said about:

"  He builds each cartridge himself and has quite a lab.
I suspect a lot of the performance comes from manual tweaking and testing. The more expensive the cartridge the more attention it gets, the better the performance. I suspect this is impractical to do on a mass assembly basis..."""

eacg single tinny detail takes from him a lot of time to achieve those kind of quality level performance and numbers.

Hi @kennyc : Always is time to learn, you posted:

"  degrees is measured vertically, while null points (zenith) is measured horizontal. Therefore, once vertical is set up, it should remain the same across the entire record surface.  ""

A pivoted arm is tangential to the grooves only at null points where I understand we can to set up in that groove the stylus tip at 90°.
You said that after we make that set up " should remain " in all LP recordedd surface and my question is: 

how can remain when at the next and before the null points in all grooves the stylus tip is not any more exactly in the grooves but with and error ( tracking error. ) that impedes the stylus tip stays exactly at 90°  in the grooves ?  why distress about when of the hundreds of grooves we can achieve that in only 2 grooves.
 Of course that maybe I'm missing something/I'm wrong and you have the explanation about for I can understand your statement and all of us could learn something that it's way critical and important as you show it.

Your answer appreciated.

kenny: dead silence, why is that? only because I'm wrong and did not understand your posts?.

Well do it a favor and at least come back and post: You are wrong.  That's enough for me and maybe for all of us.

A good Grado is good enough. Period. 

Coltrane, as long as it does not hum on your turntable!

Rauliruegas, there is a slight change in VTA with tracking error but it is so slight that it is most probably meaningless. The current standard VTA seems to be 92 degrees. I use a usb microscope and set VTA so that the oncoming surface of the stylus is exactly at 90 degrees. This seems to work well. I went through the process of changing VTA in about 20 minute increments up +- 1 degrees and could not hear a significant difference. This was with a Clearaudio Da Vinci a cartridge with a fine line stylus.
