I won't get into the meat of your post, but the pivot is not a "floating golf ball". Because it is totally enclosed, in order to keep the magnetic oil bath from spilling, I cannot really see what's going on there, but I suspect it is a constrained...

I don’t understand your last post.

Pindac, what you want to do, which is a logical way to compare overhang to underhang, seems to have been done by Intact Audio with a Schroeder tonearm. Perhaps Dave (aka Intact Audio) can say more. I think the headshell is held at an angle, on som... 
New Schiit, phono maybe big
Nearly every phono stage ever made operates in class A. And the vast majority use no feedback. So those qualities don’t help much in predicting happiness. But Schiit makes good stuff for low cost.

And my point, which apparently you are intent upon ignoring, is that the theory would predict that the Viv should sound grossly distorted (your term) compared to any decent overhung pivoted tonearm with headshell offset, and it does not, in my han... 
How are we wiring our Mono systems?
Some of my best jazz LPs are in mono, because the greatest jazz artists were at their peak performing years during the 50s, prior to the big change over to stereo. When I play a really clean mono LP of high recording and pressing quality (using on...

Dear Raul, I was wondering what took you so long to comment on my report. I am trying to take the line of least resistance, which is this: If minimizing TAE at the expense of all other possible sources of aberrant forces was so vitally important, ... 
How are we wiring our Mono systems?
The impedances (input and output) seen by the two devices would be very different in transformer connected mode vs Y connector mode.  That also would affect SQ of course.  I am actually trying to figure out how you would do it with transformers in...

Larry, in your Y connection vs transformer experiment, where did you insert the devices?

You’re making it more difficult than it needs to be, unless you want to listen only to mono LPs. Otherwise I just use a preamplifier with a mono mode switch. Next step would be to use a mono cartridge. Of those there are two types, true mono vs st... 
Need some help picking my first MC Cartridge
The Feickert is one of the easiest alignment tools to use, but it does make sense to go through the process once or twice in advance. It’s not rocket science.

What interests me is that the idea of an overhung pivoted tonearm seems to date back to about 1940, when Lofgren and Baerwald published their solutions to a question which seems to have been how to devise a pivoted tonearm that minimizes tracking ...

Based on manual pushing, pulling, and twisting, I don’t detect much slop in the Viv bearing. None in the fore and aft directions and a teeny bit if you twist with more force than ever occurs naturally during use. I don’t know how this compares to ...

Except where there’s a pre-existing zenith error of > or = 3 degrees. In that case even an overhang may have a >3 degree net TAE error.
