The coil impedance for the Miyajima Zero Mono is 6 ohms and the recommended loading is 200 to 300 ohms, I prefer mine at 300 ohms rather than 200 but your tastes may differ. The Zero can be a bear fro hum so make sure your system has either a mono switch (as the hum is usually thereby cancelled) or a ground lift option. I also got best results from a step up -- a MusicFirst Audio Classic V2 with 1:10 ratio and 80K to 10K parallel load options resulting in between 100-500 ohms seen by the cartridge. Load capacitance is generally not an issue for moving coils so I've never seen specs on this.
