I don't disagree with you,...

in fact my experience with my Urushi is consistent with what you say, assuming that at about 90 degrees azimuth the tip of the Urushi stylus is perpendicular to the groove. It almost certainly is more nearly perpendicular than it was when I aligned for electrical perfection. This was using a Triplanar, so azimuth was easily adjusted and was no factor in my results.

However, by your preferred method, the only way to align for azimuth with real accuracy is using a microscope/camera capable of imaging the stylus tip in the groove. Yes?

Evidently, the OP aligned for EQUAL amounts of crosstalk in each channel, which I assume is why he reported only one value (-30db). There is another school of thought that says to align for lowest amount of crosstalk, regardless of whether the values for each channel are equal (usually they are not, when you adjust for lowest amount). I have sometimes found that adjusting for lowest crosstalk but not necessarily equal crosstalk results in less deviation from the 90 degree ideal.
