My Sonic Lab Eminent Ex MC Cartridge
MY SONIC LAB – Eminent EX
Founded by master cartridge maker Mr. Yoshio Matsudaira in 2004, the goal was to pursue and develop the ultimate dream range of 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 a previously unseen level of performance with the lowest internal impedance (i.e. the least number of coil windings)and the highest output.
Historically there has been a trade off between higher output cartridges (e.g. 0.3mV to 0.7mV) which yield less resolution and low level detail, compared to those with an output of 0.1mV to 0.25mV. With the limitations of most of today’s phono stages the trend has been to use higher output MC cartridges at the expense of ultimate resolution.
Utilising Mr. Matsudaira’s vast experience, MSL has solved this problem by producing a cartridge with minimal coil windings (for high resolution) yet with high output gains of 0.3mV to 0.5mV, thus unleashing the musical energy during playback, yet retaining the subtle nuances and resolution. Neodymium magnets have improved this situation but MSL have also designed a high efficiency magnetic circuit, achieving their goal in the MSL Eminent EX with it’s very low internal impedance of 0.9 Ω yet with a higher output of 0.4mV.
THIS EX MODEL IS A HIGHER GRADE THAN THE REGULAR EMINENT (WITHOUT THE EX) AND IS ONLY SOLD OUTSIDE OF JAPAN.
The My Sonic Lab Eminent EX has a 0.4mv output, 0.9 Ω internal impedance whereas the regular Eminent has a 0.5mv output with 1.8 Ω internal impedance

Hifi+ Issue No. 37 by Jason Hector
“This is a powerful MC with impressive low-level resolution and a sense of speed that is quite rare.”
“It’s crisp and clear yet also muscular and hard hitting …”
“… the guitar and bass portrayed with a chunkiness that makes them seem all the more real.”
“There’s no shortage of power and weight”
“There’s no denying the strong sense of pace that the Eminent brings to the party and the degree to which it responds to each recording. This is a first class moving coil that deserves to be a front-runner for any one with this sort of budget.”
