(1) All I'm saying is skating force is proportional to VTF. The word "proportional" in a mathematical term only means that they increase or decrease in relation to one another, which relationship may not be perfectly linear.
(2) Just about any tonearm instructions I have ever seen from any manufacturer will advise setting AS at some value below that of VTF, so no one would argue with that, least of all me.
(3) Glai, I think it is more correct to say that MORE tracking error reduces skating force, not less. The whole reason we contend with skating force is because the headshell is offset at an angle to the arm tube to minimize tracking error. This is what generates the skating force. If the headshell is not offset at an angle to the arm tube, then there is no skating force but lots of tracking error. In a 12-inch tonearm, this effect is somewhat ameliorated compared to a 9-inch one. That was the rationale for the Nottingham 12-inch tonearm with no headshell offset.
I agree with you guys; I do use the very most minimal amount of AS necessary to overcome that R channel distortion and to give even channel balance. I am not sure what Glai was trying to convey in his discussion of imaging, but I think we agree; I hear the musicians kind of get squooshed together on the R side. My observation was made with my Triplanar, but I also observed similar phenomena with a Dynavector DV505. With the TP, I need to try the tiny O-ring idea.
I think the way in which the cartridge is a determinant of the need for AS is only due to differences in stylus tip shape and mass. Those factors affect groove friction. Groove friction and VTF are all that should matter, for a given offset angle of the headshell.
