Mike, is the height of the tone arm on Sol adjustable? I'm assuming, best I could tell from the video, that the pivot point is pressed into the plinth? You have probably thought of this, but it popped into my head so I'm posting it.
Could the pivot point have a fine tread and screw into the plinth and set with a simple lock washer as a relatively inexpensive way to adjust VTA? Even a set screw from the side if the point was a slide fit. Sometimes a little adjustment is all it takes to go from mediocre to wow and no cartridge nervousa is required to hear the results.
If I found the right Conrad Hoffman he's designed one very fine turntable bearing!
