MUSICAL MILLENNIUM.
If a technology is not suitable for music, you should not adopt it even if it is a high-tech.
Every technology should contribute to music reproduction.
The SR-009 is the product of the repeated research trip to technology and material search without deviating from our stance to return to live sound and music always with refined sensitivity.

 

PRIDE AND JOY
It will exactly be as a result of "work" each predecessor piled up, if a race, a company, and an individual have "pride". And it clearly depends on the way of life we live now to inherit it and to bear "enhancement" and "evolution." Simply this is proven by the fact that the state-of-the-art technologies in the world exist intensively in present-day Japan . Making valuable new things full of creativity by skillfully taking advantage of these technologies has given birth to a "millennium" earspeaker (electrostatic headphone).

 

TECHNOLOGY AND MATERIAL

DIAPHRAGM:
The newly developed sound element has been adopted in the SR-009. New high polymer ultra-thin film material called the super engineering plastics - the reinforced material of the conventional engineering plastics - is employed for the diaphragm of the sound element. Materials superior especially in tone quality have been selected to attain the extremely excellent frequency characteristic from low to super-high as well as the vast dynamic range.

ELECTRODES:
New electrodes named MLER (Multi Layer ElectRodes) have also been developed to realize the plane drive of the whole film diaphragm surface. While infinite thinness and flatness are required for the fixed electrodes, they simultaneously need to have other characteristics such as low resonance, high transmissivity of sound wave, and so on. The entirely new electrodes have been completed through the unification of metal plates processed with ultra-precision photograph etching using the high technology of heat diffusion combination on the atomic level.
