A complete guide to phono cartridge physics and history. Understand the difference between Moving Magnet and Moving Coil through the lens of legendary hardware. Every cartridge is a microscopic generator. It translates physical friction into an electrical signal. This guide explains the two ways to build that engine—Moving Magnet and Moving Coil—and tracks the history of the diamonds that defined analog audio. From the high-torque broadcast tools of the 1960s to modern precision, this is the map of the groove.
