Azimuth 2020

"Cross talk is affected by azimuth. Phase is affected by tracking error."
And phase between the two channels is also affected by azimuth.  All the adjustments on a TT are interrelated to some degree.  And these changes can be measured and heard.

Puffin seems to only measute crosstalk.  Need to measure both crosstalk and phase to optimize azimuth (a la Adjust+ or AnalogMagik).

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.

@lewm, yes you can adjust just azimuth the get best crosstalk and zero phase difference.  But that means all other parameters need to be set in the sweetspot too.  So you do end up having to go back to adjusting VTF, VTA, etc. and then back azimuth to get there.  That is what AnalogMagik and Adjust+ have taught me.  And it is worth it.
