Dear @bydlo : That cartridge needs a very well damped tonearm and that the cartridge will mates with the cartridge the range of frequency resonance and that the phono stage has high overload margin.
You are playing with load resistance but you need to play too with load capacitance and you can't do it.
""  I do not dare to touch VTA as I think I’m in the sweet spot and I don’t use VTA for tonal adjustments. ""
Why do you think are in the sweet spot? if you have the " rigth " damped tonearm and phono stage high overload margins and is reallya good phono stage: why all those troubles?
Certainly is not an easy set-up cartridge but seems to me that you are testing at random with out have well defined your targets according your system limitations, nothing is perfect.
Maybe the change on VTF that noromance posted helps him but is not a very good advise to set the VTF lower than the manufacturer specs especially with cantilever-less cartridges that could makes more gharm to the LPs than good.
Regards and enjoy the MUSIC NOT DISTORTIONS,
