Dear Geoch, no problem - it is just that I don't have the patience right now to go into this topic step-by-step.
In general my position is, that so far tonearm alignment is seen in a way too small perspective. There is more than just the two zero points and average or maximum distortion figures. It is very important where these zero points actually are located and where the maximum distortion figures occur on the arc over the record side. The actual curve of the groove gets ever smaller and as such it is IMHO very important to get very low distortion figures close to the innermost grooved area. But not in the narrow minded way that the Stevenson alignment concentrates each and everything on the DIN or IEC limit of grooved area.
The actual offset angle of a tonearm in comparison and sometimes in fight with the actual offset angle determined by the alignment curve is another topic which can significantly influence the skating force - and such the sonic performance.
Wherever I have re-aligned a tonearm/cartridge in set-up and systems of befriended audiophiles I always earned amazement due to the improvement in sonic performance.
No mystic - no "secret" here, just care, a view from many different point, precision and attention to detail.
Cheers,
D.
