bydlo,
First, the sequence of events is dependent on the cartridge and the pre-amp. One of the premises of this entire thread has been the limits of 'some' pre-amps.
This article is an extension of the first Shure article I referenced, and it goes deeper into the cantilever stiffness, with the risk of mistracking at high velocity. http://pspatialaudio.com/analogy.htm#cantilever. This mechanically induced instability will lead to harmonic distortion.
From this article https://www.analogplanet.com/content/current-affair-intriguing-mr-labs-vera-20-mc-phono-preamplifier, the statement is made that LOMC "Moving coil cartridges output very low voltages but relatively high current on the order of tens of micro-amperes". Dynamic microphones that operate on the same principle, state current output. https://www.audio-technica.com/cms/site/b0d226992d31e25d/index.html/
Depending on the pre-amp, using this as an example, https://sound-au.com/project06.htm, if there is a line to line capacitor with no dampening resistor, and IF the capacitor saturates from the harmonic distortion, then the events should be setup for a high current to occur. So, it may be that the mechanical instability begins the event, but the consequence is that a small mistracking event can cause harmonic distortion that because of the poor preamp design leads to an even larger mistracking event.
