Dear @atmasphere : Your post is not an answer to what I asked to you:
"""
how did you measure that " limit trace " as a function of loading and which is the point/value where the loading figure starts to " limit trace " abilities in the cartridge? """
that is what needs a more specific answers because you posted here and in several other ocasions:
""" will limit the ability of the cartridge to trace higher frequencies .."""
Lewm my answer to you is that other than " science " we have to use common sense and here what I posted before to you:
""
did you know how much " force " do you need to apply/need/ at the base of the cantilever to really impedes at the stylus tip position its free movements, a tiny movement? no?
Btw, do you know the " power forces/inertia " generated at the stylus tip when ridding the grooves at 33/45 rpm and what " force " is need it to " limit the trace " of the stylus tip to track when appliyed that force/loading at the other end of the cantilever? ..."""
Which is the force need it to broke that very high inertia generated by the friction between the groove modulations and stylus tip when the cartridge is ridding/tracking those grooves that can " limit trace HF "" ?
I don't know that answer concerning the loading resistor value to broke that inertia. We have to think that load resistance takes its effect at the cantilever base and the stylus tip is ridding at the other end/extreme of the cantilever and this makes " things " extremely complicated to that " limit trace " issue.
That theorical electrical loading effect is converted in mechanical energy ( the " force ". atmasphere said: stiffer the cantilever. ) what makes it even more complex due that in the mechanical land we have to take in count several parameters as: compliance of the cartridge, cantilever length and overall dimension and characteristics, status of the stylus tip because if the cartridge has over 1.5 khours of use its own tracking abilities changed that when the stylus had only 300 hours and not only that but even its compliance through more playing hours could changes too, the stylus tip inertia is different depending its position in the overall LP grooves and other parameter to take in count is the different velocities recorded through the LP grooves surface, etc, etc.
So, till now exist no true evidence that that " limit trace..." can happens.
@atmasphere can you answer the original questions?
