Whats the difference between a moving magnet and a moving coil cartridge?
In a moving magnet cartridge (MM) a small magnet is attached to the stylus. It moves relative to a coil built into the cartridge. Because of the size/number of coils the output voltage is relatively high. A moving coil cartridge (MC) has small coils attached to the stylus with magnets built into the cartridge. The coils are electrically connected to the cartridge output pins by fine wires. Because of the need for the coils to be small and light the output voltage is relatively low. What is cartridge loading To load a cartridge you add some kind of electrical damping to the otherwise open coil. Usually this comprises a resistor and capacitor. “With the resistor you apply some damping overall, especially in the bass. You can tune imaging and bass attack and midrange warmth with the resistor. The lower the resistance, the higher the damping. Some cartriges have high mechanical damping, they are tuned to have the right damping even without electrical load, some cartridges have low mechanic
