Hana SL vs AT Art 9


Has anybody compared these two cartridges on their Turntable

Compare two videos on Analog Planet, one from Hana (Excel Sound) factory tour, another one from the Audio-Technica factory tour by M.Fremer. 


From technical point of view Allnic AUT 2000  step up's what about cartridge matching impedance wise? I have found nothing about it.

Hana SL has weird specs -  recommended impedance of >400 ohms.
IMO Hana ML at least from the first glance is easier to get into sweet spot - <100Ω (ML) . 

Why is the recommendation of >400 ohms for load resistance "weird"?If you use a 1:10 Step-up into the typical 47K ohm load resistor of an MM phono stage, you end up with the cartridge seeing 470 ohms. Just right for the SL.
You know good SUT with step up 1:10 and recommended impedance 30?
Allnic AUT 2000  on x 13 if it's not tuned should give ~ 300 ohms natural impedance.
