@lewm I 'tip my hat to you' for being this adventurous.
The descriptions on offer from your early usage are quite interesting, they certainly suggest a perception is in place where the important instrumentation in a recording are now 'lesser constrained' in their presence, in freer space and possibly perceived as more honest/real? .
The idea that Three Models of Cart's have also not received any criticism, suggests the impression made can be ubiquitous and extend into further Cart's.
I also like the way the thoughts are already onboard about how to further eek the presentation to ones own unique preference by suggesting the combinations of materials that can be used for Wand and Headshell, as for the Headshell, I see these options extending beyond your own suggestions.
If 'lesser constrained' is the correct description for your musical encounters, it is this as a description that was the deciding factor for myself to remove from regular usage, Tonearms designed around copied Rega Design.
It is quite easy to understand why there will be variety to the methods adopted to be used with AS.
The use of AS is to set up a force to be applied to the modulation on the Grooves Side Wall.
At some point this force and the mechanical energies being produced as result of the set up, will be detected as having an audible effect.
The levels of recorded data within the modulation is to vary across different Vinyl LP's and in some cases different pressings of the same LP, will also be causing different impressions in relation to the chosen AS force.
If one were extremely anal or sensitive enough to the effect being detected, to the point they become biased. AS can easily become a setting that one feels will benefit the audible sonic if it undergoes constant alterations.
The other extreme, and one that might just prove the better of two evils, would be to remove the effects of AS to the point it is perceived as having almost zero influence on the audible sonic.
