What is your to earl’s Maximum Distortion %?

I would be looking for whether there are any head shell options that allow the cart to move further away… assuming it has a detachable head shell.
There are on-line calculators that give you the pivot to stylus distance

And the just plug in 225mm to get the the distance, and compare that to the 222mm distance
222mm: 239.296
225mm: 242.082

My Korf ceramic HS on the old arm, looks like it just has about an 1/8” of room to move it further out.

I would certainly start there if it was my arm, and then worry about azimuth and Zenith and SRA.

It’s a Grace 707 - the headshell is not removable, unfortunately (in this case).

My earl is not distorted at all

Earl called. He said his views on tonearm alignment have been distorted.

How does one measure the distortion made by the cartridge and arm?
