My Sonic Lab Signature Gold Phono Cartridge

The sound of My Sonic Lab cartridges are the result of master cartridge designer Yoshio Matsudaira seeking natural reproduction by minimizing signal loss, internal distortion, and phase distortion. All My Sonic cartridges utilize Matsudaira-san’s unique SH-μX magnetic core. This special core material has higher permeability and flux density than the typical iron core material used in MC cartridges. It allows My Sonic Lab to use fewer coil windings than other moving coil cartridges, minimizing music robbing distortions and maximizing signal output. This high efficiency approach equals wide dynamic range, fast transient response, low distortion and high signal-to-noise ratio. In other words, expect tremendous natural detail and clarity and to hear new layers of information in your favorite records.

The Signature Gold was released for My Sonic Lab’s 10th anniversary. Matsudaira-san evaluated every aspect of his previous Eminent designs for areas to be improved. A stronger two-component chassis, higher grade internal wiring and improvements in the suspension led to a more refined sound. However, it is the 10% larger SH-μX core that makes the Signature Gold excel at energetic expression and power. Compared to the Eminent designs, Signature Gold has more extension, slam, power, and dynamic range.
