Dynamic vs Static VTF on a SME V. Can someone explain the differences in sound?

I've been playing a bit with the percent of dynamic vs static VTF on my SME V. As noted in other posts, a mostly static VTF seems to be a bit faster, more transparent, but also leaner, flatter and less rich. A mostly dynamic goes in the other direction, richer, more textural, more bass, but somewhat less transparent and a bit slower. Now these differences are with using the exact same VTF measured with a good digital tonearm scale. Can someone explain the differences in sonics between the two? I would guess it must have something to do with physics.....as does everything......  :)

I have found that a combination of the two , in my system, gives me the best results, but as I said, I am curious as to why.

Dear @jim94025  : Normally dynamic VTF mechanism uses a spring and this fact make what @dover  posted: " audible  "mechanical noise" . This simple fact means that no matters what a static VTF set up using just the force of gravity will degrades less the cartridge signal.

Normally going against the  gravity's force is not good in a tonearm because there is no true flat LP surfaces : always exist waves at micro and macro levels and in the dynamic VTF the tonearm will be try to mantain always the same tracking force level and this says that during the tracking of a wave in the high crest the cartridge suspension is suffering/distressing changing too the VTA. The static VTF permits that that happens in more gentle way with lower suspension distress. Maybe under some specific scenarios the dynamic VTF could help in some way to the cartridge tracking but as always been staic or dynamic exist trade offs. I prefer to use the gravity's force in this specific VTF issue.
