There is no general rule for the VTA (and the results), probably some explanation will be useful:
1. All up and down (VTA) is depending of the angle the grooves were cut into the record.... different years, different angles, different labels, no Standard...
2. The diamonds from the cartridges have also some influence (Shibata, Paroc....), but even more important the polishing of the diamond (contact area). When the angle is "right" into the groove, you simply habe an optimized contact area and you will hear more details, specially in the higher frequencies.
No matter what Arm or cartridge you use, it depends on your own findings.
Let#s talk about an original from the 60's, done with a few microphones...normally the Arm has to be a bit lower in the rear, when you do that, the sonic result is like "zooming into the Soundstage", it gets wider and you are more "in it". When done wrong it is like listening to a "point source" between your speakers.
