As a "newbie" (about one year) to analog, I cannot debate the views expressed here with any authority but I am interested in continuing to learn and improve my sound. My approach to setting VTA and azimuth has been to use a little bubble level with double stick tape, centered right over the arm pivot point to level the arm (with the needle dropped into the groove). I can very precisely adjust the VTA and azimuth of my armbord on the fly with this approach. One eighth of a turn in the allen bolts of the arm board is easy to detect with the level. Also, the record clamp causes the record to be pitched down towards the edge and this angle can be matched in the cartridge.
This is probably a "crude" adjustment by above standards but I am pleased with the sound and it seems that most used records have warp, even with a record clamp, that is 10 times the tollerances mentioned. Like the original poster, I am wondering if I am missing a great deal by not paying more attention to this? I would suggest to him that flatter records ( perhaps by using a rim weight) would need to be the first priority before more criticality in VTA adjustment.
