My Sonic Labs
The “My” in the company name My Sonic Lab refers to the initials of its designer: Mr. Y. Matsudaira who founded the company after an illustrious career spanning over forty years designing cartridges, phono stages and tonearms . He started at Tokyo Sound Co. in 1959 and moved to Supex Co in 1967. In the 70’s, he was invited to be part of an independent development team for masterpieces by the top-brand phono cartridges like Koetsu, Miyabi etc. He joined Audio Craft Co in 1981 as chief engineer and presented such exquisite works as the AC-3 stereo cartridge, the AC-3300/4400 tonearms, the AR-110/110L turntables, the TS-200 MC transformer, the PE-6000 Signature phono amp. Mr. Matsudaira realised his long cherished dream, when he formed “My Sonic Lab” in 2003, and introduced the EMINENT high-output, low-impedance MC cartridge and the matching MC transformer Stage 202. With My Sonic Lab, Mr. Matsudaira has fulfilled his design goals of producing a moving coil cartridge with very low internal impedance. With this design, Mr. Matsudaira feels that the energy producing potential of an MC cartridge is fully realised. Mr. Matsudaira uses an ultra high-μ material that he has named SH-μX. This material allows My Sonic Lab to significantly reduce the amount of coil wire required to give a decent output level. With the reduction in the amount of coil wire comes greater low-level resolution. My Sonic Lab cartridges achieve their reputation as absolute reference standard components because of their ability to excel in all aspects of analogue sound reproduction and audiophiles often describe them as having that elusive “magic”. It’s all there …energy, dynamics, detail, nuance, liquidity. Once you have heard one of these in a well set-up system, you will realise that only someone of Mr. Matsudaira’s experience and heritage can produce something this special.

MY SONIC LAB –  Eminent EX

The goal of any MC cartridge design is to achieve high energy (maximise output) from a low impedance circuit. (i.e. the least number of coil windings)

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.


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

MSL Eminent Review Audio Asylum

Stereophile Analogue Corner Review

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.”
