Cartridge Tonearm compatibility

Hi,
I need some help calculating cartridge/tonearm compatibility. I am considering building a DIY turntable. I have purchased a Maglev table and a Jasmin motor from China on ebay. I am currently building a custom plinch and arm-board.I have purchased a Jelco SA750E tonearm. I am considering a Dynavector XX2MKII cartridge. I have looked at resonant frequency calculators but quite frankly they are above my knowladge. Would the Dynavector XX2MKII be a good match for the Jelco SA750E. The tonearm mass is 13.26gr. The cartridge weight is 8.9 gr and the cartridge compliance is 10 mm/N.

This is a compliance at 100Hz
You need a compliance at 10Hz or all your calculations will be wrong. 

To convert 100Hz to 10Hz you have to multiply on 1.7
So the actual dynamic compliance of your Dynavector is 17 cu ! 

Use 17cu when you calculate tonearm/cartridge resonance.

Can you believe, I built this turntable and never once considered any of that technical mumbo jumbo? https://systems.audiogon.com/systems/8367

Not a Maglev as in the floating platter table?

Right. Clearly someone is not thinking practically.

No, It's not the levitating platter table but the spindle bearing is a Maglev design using magnets to suspend the linear bearing surfaces.
