Chakster, I guess the "operating principle" of the MP cartridges is not being used to "decrease inductance", per JCarr's summation, because the MP110 has very high inductance according to any info I can find on the internet. The operating principle seems to be used to increase output, because the output of the MP110 is MM-like, even if it's not an MM cartridge. So we have an IM cartridge that measures like an MM, both in voltage output and (high) inductance.
Raul, if the MP110 has inductance of ~800mH, as per VE discussion groups, then its resonance can fall well below 20kHz, if capacitance and R are not adjusted to prevent that. And Mijostyn, if the foregoing is true, then it does help the OP to understand why ticks and pops may seem prominent, and it gives him some idea what to do about it.
To paraphrase Albert Einstein, it's good to keep things simple, but not so simple that a valid hypothesis is ignored.
