Sorry, I don't think that you read my response correctly.
The Zephyr is not a moving coil cartridge, it is a moving iron cartridge like a Grado. It has high output and is responsive to both changes in capacitance and resistance, just like a MM cartridge.
The only difference is that in a MM cartridge a small magnet at the end of the cantilever varies a voltage in a fixed coil, where as in a moving iron cartridge both coil and magnet are fixed and a small piece of iron on the end of the cantilever varies the voltage.
