My Sonic Lab Eminent EX Moving Coil Cartridge

In creating the Eminent Ex, master cartridge designer Yoshio Matsudaira focused on natural reproduction by minimizing signal loss, internal distortion, and phase distortion. This cartridge features Matsudaira-san’s unique SH-μX magnetic core that has higher permeability and flux density than the core material typically used in MC cartridges. This allows for fewer coil windings than other moving coil cartridges, which minimizes distortion without lowering signal output levels. It is a high-efficiency approach that offers wide dynamic range, fast transient response, low distortion, and high signal-to-noise ratio.
