Mark, here is the the point that I make. You said that no matter which direction I went off of the baseline you couldn't hear much of a difference. Then use other methods (microscope or not) you did found the direction and distance from that baseline that did deliver the improvement. All that I am asking is why while you were trying to hit the same “VTA sweatspot” you were not able to do it.
I do admit that Wally's method might be much easier, particularly if an arm has no calibrated VTA adjustment. Wally is very intelligent guy and I have a lot of respect to him. Still, I do not think any objective and measurable approach to VTA makes sense, at least to me. I do not write a verdict on the subject, I just do not feel that any universal roles might be made in this. It did work in your case and this is great. I would ask why you suddenly begin to hear it but it is kind of irrelevant. Set VTF for .2g more or load the cartridge with half of the impedance that you are currently loading and see if the Wally’s measurement principles still hold. I do not think it will, however I did not read the thing to say anything more.
