Break a moving coil and there is no simple fix

A moving magnet forgives the accident with a new stylus; a moving coil makes the accident a far bigger bill.

KDAbout 2 min read
Two phono cartridges side by side on a velvet tray under a jeweller's lamp, one with a spare stylus beside it and one without.

Every cartridge comparison talks about tracking and detail. Almost none of them talks about the day you break one. I learned that part with a cleaning cloth, and I nearly fainted in my dealer's store when I heard the price of the repair.

In a moving magnet, the magnet moves between fixed coils, so there is more mass bouncing around in the groove. They typically cost $50 to $300, and the stylus is replaceable at 30 to 70% of the cartridge price, depending on the manufacturer. Break it and you buy a new needle. Crisis almost averted.

A moving coil reverses the design: light coils move with the stylus and the magnet stays fixed. Less mass means it tracks the groove more precisely, and the detail retrieval is noticeably better. But prices run from $300 to tens of thousands, the output is low, and you need a competent phono stage or a step-up transformer. And when you break the stylus, there is no simple solution.

That is why I tell beginners to start with a good moving magnet and live with it for some time. Do not jump straight to a $3,000 moving coil. You will not appreciate the difference yet, and if you break it, and trust me, you might, you will hate yourself.

Choose the cartridge for the sound. Choose the type for the accident you will one day have.
