Pivot to Spindle distance

if it ain't right, it ain't right

Sounds spectacular with my redoing the entire setup.

Yes, I could have told you that. Probably everyone here has heard this before, but the thing is most people while they want to believe they think and figure stuff out the truth is they mostly repeat what most people say. Because if a lot of people say it then it must be true, right? 

Study those diagrams above, which you might as well, I'm not about to waste any more time on it. Same old. What they show, if you think about it, is no pivoted arm is ever tracking correctly except at two theoretical points. All the rest of the time it is off one way or the other.

Therefore, logically, no matter how much time you put into it or how perfectly perfect you get it, it's perfect for like one nanosecond per side. All the rest of the time it is off, and a lot of the time by a lot!

Only, funny thing, no one ever seems to notice. No one. Ever. In the freaking history of records. People sick and tired of me saying this, but nowhere near as sick and tired as I am having to repeat patently obvious truth that somehow never manages to stick. Something like 90 plus percent of the sound you get is the needle being drug through the groove. If you get VTA and VTF right, there's another 5%. Very last thing on the list is the alignment that is affected by P2S or overhang. 

Absolutely the least important of all alignment parameters. AS YOUR EARS ARE TELLING YOU! But funny thing, audiophiles never really seem to trust their ears.

We now return you to our regularly scheduled non sequiturs.

Lewm,
I used that term loosely. The diamond follows the arc on my Wallytractor and the cantilever is parallel with the null points.

@millercarbon

I like the way you put it - and phrased it. 
Who CAN argue the point(s) you make?
I ... at least can't - and I won't. 👍🥂

If you search my posts you will find that I have answered this question over and over. The answer is an emphatic no. If you have headshell slots and can reach the overhang spot exactly, all is fine. 
There is a certain person on this board, on this thread in fact, who again and again espouses false truths. It is annoying as can be. And I ain't talking about Millercarbon who though has his own picadellos at least knows the basics of turntable set-up and geometry. 
And while I am in a mood for ad-homynym references, Lewm knows his stuff too. I am a bit surprised by his response in this thread though. 
Look, your cartridge knows nothing of P-S. It only needs to be able to trace the proscribed arc for a given alignment and if overhang is reached, it will. For a given tonearm, P-S only affords adjustment for the largest range of cartridges with various mounting hole to stylus tip distances ASSUMING headshell slots.
