The Lowest Loss With The Highest Output.

Founded by master cartridge maker Mr. Yoshio Matsudaira in 2004, the goal was to pursue and develop the ultimate dream cartridges. Mr. Matsudaira has been a highly sought after designer of high performance cartridges, with a client list that has included respected brands such as Koetsu, Air Tight, Miyabi, Luxman, Supex and Audio Craft. His unique SH-μX high flux / high permeability core material is one of the few genuine breakthroughs in cartridge design in the last fifty years. Only with the development of SH-μX was it possible to achieve an unseen level of performance with the lowest internal impedance and the highest output.

Ultra Eminent EX

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.

This Ultra Eminent EX resides in the middle of the My Sonic Lab family. Compared to the standard Eminent EX and Hyper Eminent, the Ultra has much lower internal impedance (and output) and a boron cantilever. The result of these improvements are lightning fast transient response and pinpoint precise sound staging. Ultra Eminent EX reproduces complex music with ease and master tape sound quality.

“… the Ultra Eminent Ex’s presentation sounded like analog tape. I believe this was caused by extreme amounts of low-level detail. The (Ultra) Eminent Ex retrieved so much microdetail that I swore I could hear right through the grooves to the analog tape passing across the recorder’s playback head.” -Herb Reichert, Stereophile
