MUTECH RM-Hayate Ring Magnet Cartridge Runs Rings Around Competition
December 22nd, 2025
Release Notes from Mutech:
Eiji Kanda, the founder of MUTECH, passed away in 2020. HAYATE is produced by Hiroki Kajihara of Kajihara Lab Co. who inheriting Mr. Kanda’s will and technical knowledge. The cartridges are manufactured by Hiroko Ishiyama according Eiji Kanda’s Blueprint.
The Ring Magnet Structure is not the Ortofon type Magnet Structure which has the core material placed in a virtual magnetic field created by two yokes. A Ring Magnet structure has the core material placed inside the magnetic field produced by a tubular neodymium magnet.
Our special core material named “SS-μM”, is placed inside an N50 magnet, one of the strongest magnetic materials made, maximizing output of the core material. Additionally, we plated the magnetic materials with gold to prevent oxidation and deterioration of the magnetic circuit.
The cantilever is boron, and the stylus tip is a line contact needle. A new thicker OFC material has been adopted for the coil, and by using a single-layer winding, inductance has been minimized for improved high frequency performance. Single-layer windings also prevent capacitive coupling between winding turns, preventing changes in frequency response.
The cartridge pin construction was reviewed and new OFC materials from Proterial Metals, Ltd has been adopted. The pin plating has been reviewed and has changed from rhodium to gold plating. This gold plating by Cross Point Ltd. is special thick one. Gold has lower resistance than rhodium, and is a better choice since almost all cartridge clips are gold plated. Whenever possible, it is better when both connections are made of the same material.
A new, dedicated solder was developed for connecting the terminals and coil lead wires, which has also succeeded in improving the dynamic range and low-frequency reproduction. This solder allows good connections to the gold plated surfaces without “gold poisoning” of the solder joint.
