Hi,
I think the MP-500 should work on your arm. I've never tried it, but the 100Hz compliance should be equivalent to 16.5 cu @ 10Hz ?
With hardware weighing 1g, your resonance should be around 8.5Hz. Even if it went a tad below 8Hz, it's not the end of the world. If your physical set-up is relatively immune to footfalls, and physical excitation, you should be fine.
I can't comment about resultant SQ and like I said, I've never tried this cart, but the rules of cu and arm mass are often broken on the low side of resonance, with good results.

Thank you very much for your reply! I used the effective tonearm mass spreadsheet created by user Luckydog to calculate my tonearm's mass with both my current cartridge/headshell combo and the MP-500 one, which is heavier. That extra weight, plus the fact that the maximum recommended VTF for the MP-500 is slightly lower, increases my tonearm mass considerably.
With that measurement, I used the cantilever resonance frequency spreadsheet that can be found at The Analog Dept. and the resulting resonant frequency is 7.42 Hz, which is far as I understand is problematic. Just in case you feel like making some calculations on your own, here's some relevant data about my turntable's tonearm:
Effective length: 230 mm.
My turntable has the particularity of having interchangeable tonearms (S-shaped and straight/underhung), so I was able to remove the S-shaped tonearm tube (I never use the straight one) and weigh it alone: 14 grams.
Tonearm weight without cartridge/headshell and counterweight (but attached to the base): 5 grams.
Counterweight: 76 grams.
Distance from pivot to counterweight center at the usual location (with Nagaoka MP-110 cartridge @ 2 grams VTF): 54 mm.
Total weight of my current cartridge + headshell assembly (Nagaoka MP-110 with Numark headshell): 16 grams.
MP-110 cartridge weight according to manufacturer's specs: 6.5 grams.
MP-110 dynamic complliance @100 Hz: 6 cu.
The Nagaoka MP-500H (MP-500 with headshell) has the following specifications:
Cartridge weight: 8 grams.
Headshell weight: 13.5 grams.
Dynamic compliance @ 100 Hz: 8.5 cu.
Maximum recommended VTF: 1.8 grams.
Thank you one more time!
