How does one measure the distortion made by the cartridge and arm?
What is your to earl’s Maximum Distortion %?
[Header meant to be: “What is your TONEARM’S maximum distortion”. I have been reading many comments about Audiogon randomly (or not) putting in typos, and it seems this may be the case!]
I’ve been playing around with different cartridge mounting, as a Grace arm the plinth of my Lenco cannot be mounted at the recommended pivot-to-spindle distance of 222mm (closest it can get is 225mm).
My best figures in theory seem to be:
Max. Tracking Error: 3.51 degrees
Max. Distortion: 1.21 %
Average RMS Distortion: 0.73 %
This is with: P-t-s 225mm; overhang 11mm; offset angle 19 degrees.
What are your figures for your setup?

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. 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. |
