Moving Coil & Moving Magnet Cartridges (MC/MM)

Moving coil (MC) and moving magnet (MM) cartridges are the two main ways a phono pickup turns stylus motion into an electrical signal. The choice sets the phono stage gain and loading a turntable needs. Both types fit standard tonearms and headshells.

What MM and MC cartridges are & why they matter

In an MM design a small magnet on the cantilever moves near fixed coils, giving an output of around 4-5 mV and usually a replaceable stylus. An MC cartridge moves tiny coils inside a magnetic field, so output is lower, often 0.2-0.5 mV. MC models need more gain, a step-up transformer or an adjustable load, and the stylus is serviced by the maker. High output MC models narrow the gap with MM levels.

What you'll find in this tag

The tag mixes cartridge launches, phono stage news and a long comparison guide on MM against MC. Cartridge stories cover cantilever materials, body woods and magnet types from Hana, Vertere, Rega, JICO, Homogenix, Analog Relax, Excalibur, Segno and Gryphon. Phono preamplifier entries come from EAT, AVID, AVM, MoFi, Rega and KECES, with balanced inputs and external power supplies.

Notable cartridges & phono stages

Vertere Ruby One uses a ruby cantilever. Rega Nd9 is the flagship MM cartridge of the British brand. JICO Clipper MM has a conical S-shaped aluminium cantilever. Analog Relax EX700 has a body made from Tyrolean spruce. Segno Maya relies on a samarium-cobalt magnet. Hana EL Mk II and EH Mk II are updated low and high output MC models. AVID Velsonic is a two-box MM and MC phono stage.
