RE: Kiseki Blackheart Compliance

Japanese usually publish compliance specification at 100Hz. The specifications indicate a lower compliance than you quoted (16um/mN).

There are different opinions on the optimum LF resonance range but I wouldn't obsess over it too much. The V is very broadly compatible with most medium to med/low compliance cartridges on the market today.

The standard recommendation is for LF resonance to be in the range 8 to 12Hz. Bruel and Kjaer have suggested 10 to 12 Hz and some suggest even higher to around 14 to 16Hz.
What matters more is how well damped the response is at resonance.
I personally find that 10 to 12Hz is a better range to aim for; I have many high compliance cartridges that hit 7Hz in my arm. I flatten and centre all my records so this doesn't cause any technical issues for tracking, but piano notes can sometimes reveal LF resonance related warbling. With a LF resonance > 8Hz, the warbling is not audible and once we get to 9 to 10Hz, the sound becomes very realistic and stable with silent backgrounds.
