Azimuth 2020

Been there, done that. Even if you get crosstalk correct, you cant get phase difference correct with mirrors, macro cameras, voltmeters, etc. You may get close if you are lucky. Plus, many carts are out of spec in terms of crosstalk so getting them equal sometimes is incorrect. Once I was able to verify this error with one new cart using software. It was quickly replaced by the dealer. Need both crosstalk and phase to be correct for azimuth, the latter you need to measure.

WOW!
What the f..k!
I adjust it by ear on my VPI
I adjust by Foz on my ET 2.5

Hi fi news test record is good so is the soundsmith method

Peter Lederman is the last person I would take advice from ...

Really? Lederman has a decades-long track record as a designer of speakers, electronics and phono cartridges. He and his team at Soundsmith also provide expert service on audiophile equipment - including tricky things such as Tandberg TD20As - and I’m saying that from firsthand experience. So I’d be inclined to consider his advice, even though I may not always heed it.

The vast majority of us have offset tonearms. Because of the offset as the arm goes up the stylus leans toward the spindle. Azimuth in offset tonearms is elevation sensitive.

Huh? For that to be true, you’d have to have a horrible misalignment between the turntable platter and the pickup arm. If the platter and pickup arm base are both level, azimuth cannot change as you change VTA, even if you want to call that "elevation."

I suppose it’s possible that the pickup arm itself could be defective, such that the arm could not be raised in a perfectly vertical fashion. I’ve never encountered that, though.

Cleeds, Lederman is a business man and obviously his approach has worked on you. Everything he belches is common knowledge except for the stuff he makes up like "jitter." When he says "jitter" just replace it with "miss tracking."
 As you raise the VTA of an offset tonearm the stylus leans towards the rim of the platter. As you lift the head shell the stylus leans toward the spindle. Everyone, imagine your arm sticking straight up. What position is the stylus in? Now imagine you arm straight down. What position is the stylus in? Nuff said.
