STAX / SR009S

The SR-009S is a condenser type ear speaker that incorporates the second generation fixed electrode ""MLER2"". By incorporating the newly developed MLER oval type sound unit, extremely low resonance is achieved. You can enjoy clear and realistic sound as if you are listening to a performance right in front of you.

■Second-generation fixed electrode MLER2
・The multi-layer fixed electrode MLER (Multi-Layer-Elect-Rords) established in the SR-009 has evolved into MLER2. The finish etching process that smooths the edges of the electrode opening reduces air resistance and further improves sound wave permeability. In addition, the electrode itself is gold-plated with a high specific gravity to minimize the resonance of the ultra-thin electrode. At the same time, the gold plating reduces the electrical resistance of the electrode itself, opening up new horizons in high speed and clear, silky yet powerful texture and pitch in the fundamental range, and precise reproduction of the so-called three-dimensional coordinates of the whole tone.
■Newly developed MLER oval sound unit
・The new generation oval fixed electrode MLER (Multi Layer Elect Rods) is adopted, which utilizes thermal diffusion bonding technology that integrates metals at the atomic level under high tones and high pressure to achieve flatness, low resonance, and high sound wave permeability while making the plate thickness thinner. The vibration-damping bridge is integrated, achieving extremely low resonance.
■Original wide low-capacity hybrid cable made of 6N (99.9999%) OFC + silver-plated soft copper wire
- The highly rated 6N OFC (φ0.14 x 3) is used for the center wire, and six silver-plated soft copper wires (φ0.08 x 9) are arranged around it. The overall structure is the most suitable structure for electrostatic type voltage transmission, and inherits the wide original parallel type that reduces the inter-wire capacitance to the utmost. The ""freshness of the sound"" is not compromised in the slightest.
■Arc ASSY
- 10-step click separates position adjustment and load to distribute the load. Once adjusted, the optimal position is always maintained. The soft texture of the headband provides a light wearing feel. Comfortable even for long periods of listening

■Genuine leather ear pads

New ear pads carefully crafted by craftsmen using genuine leather (sheepskin) with excellent breathability that maintains a good humidity environment for the entire ear, and cushioning material with just the right amount of elasticity. Dramatically improved ""sound freshness"" and ""sound quality""
