The issue that's false is that exist mistracking when more current running through the cartridge.
I don't think anyone has stated that this leads directly to mistracking.
The issue is that mistracking not that cantilever stiffness. It's you
who need to prove with measures that can gives the rigth answer to that
question I made it two years ago and that you never answer.
That is probably because I never stated anything as you seem to be implying here. I think this is probably because I use English as my main language and you don't; this apparently has resulted on a misunderstanding on your part.
What I *have* stated is that loading affects the stiffness of the cantilever. And further, that this could affect its ability to trace high frequencies. But I can see that this statement can really be misinterpreted. Note the use of the conditional 'could' in the sentence, as well as the rather ambiguous 'high frequencies'.
So let me put this another way. Most cartridges easily go to 40 KHz, I've measured this by cutting signals that high on my lathe and playing them back. Now we know that loading down the cartridge makes the cantilever stiffer. Are you saying that if the cantilever were ***easier*** to move, that it was less stiff, that it would not trace high frequencies as well? If the answer is 'no' then you have to accept that if you make it stiffer, at some point (maybe well out of the audio band) the ability to trace higher frequencies might not be as good.
Now the other aspect of cantilever stiffness is the mechanical resonance that the arm/cartridge compliance system exhibits. Making the cantilever stiffer is another way of saying that you reduced its compliance. Are you saying that by reducing the compliance of the cartridge that such will have no effect on the mechanical resonance? If no, then you accept that the mechanical resonance is affected by the compliance of the cartridge.
