L/i 50 EXs

The highest grade of L/i 50 series, the world standard

Audio Excellence Award 2005、MJ Technology of the year 2004



As the leading specialists in Japan, we have continuously concentrated on developing the ideal cable and its accessories for more than 20 years. Although we have realized that there are a few variations of connectors, even though there are many variations of cables exist on the market. Finally, by applying years of technical experience and know-how, we have achieved to release L/i 50 EXs with our original "P/C-037" connectors.

The structure of L/i 50 series is star-quad structure which we have trusted for 20 years. Due to its cancellation effect of opposed wires, it blocks internal and external noise without increasing electric capacitance. For the connector of L/i 50 EXs, we employed our original connector: P-037 and C-037. The highly transparent sound character of P/C-037 accurately describes the edge of sound source.

Under the strict quality-control, the all components are made from fine material and enhanced their accuracy domestically. In other words, it is completely MADE IN JAPAN.

L/i 50 EXs provides you the fast transmitting capability, high-resolution and extensive sound stage required to meet today's audio standards.



The conductor of L/i 50 series is made of highly-pure OFC. It is processed by long time annealing process in low temperature for stress removal. Therefore, the internal composition of the conductor is equalized and it actualizes stable electric transmission.


For the insulation material of L/i 50 EXs, we employed reinforced silicon rubber which has excellent vibration damping property and mechanical strength. It absorbs vibration generated by instant current addition changing.
Star-quad structure

Star-quad structure

The star-quad structure is employed for L/i 50 series. Due to the fact that stranded wires counteract to cancel magnetic field each other, the star-quad cable attenuate noise internally compared to regular cable.
Each wire is covered by reinforced fiber sleeve in order to deaden resonance between wires. Moreover, carbon is included in the sleeve for the generation of semiconductor layer to prevent electro-static charge.

Exterior cover

Polyester fiber tube with antistatic treatment is used for the exterior cover of L/i 50 series to prevent form frictionally-induced electrostatic.

Plug / Connector

We employed our original, P/C-037, for the connectors of L/i 50 EXs.
The contact of P/C-037 is made of deoxidized phosphor bronze. The plating is a combination of silver (1.5μ, inner) and rhodium (0.3μ, outer). The highly transparent sound character of 037 accurately describes the edge of sound. The P/C-037 caused a sensation due to its unique, lively and transparent sound.

Electro Magnetic Absorber

E.M.I (Electro・Magnetic・Insulation) tapes is included in the package. Please wrap it around connectors according to your preference.
