SR-X9000

|
Electrostatic Earspeaker (Flagship Model)

Electrostatic Earspeaker (Flagship Model)

The SR-X9000 represents the absolute pinnacle of STAX electrostatic headphone design. As the new flagship Earspeaker, it combines decades of engineering expertise with breakthrough technology to deliver extraordinary speed, transparency and realism. At its core is the newly developed MLER-3 (Multi-Layer Elect-Rords) system — an advanced four-layer fixed electrode structure that dramatically improves rigidity, reduces resonance and allows sound to flow with remarkable openness and precision. The result is a listening experience of breath taking scale, detail and naturality.

Please note that to drive Stax electrostatic earspeakers, you need a specialised amplifier, see our selection here.

The development of the SR-X9000 draws on more than 20 years of research into metal mesh electrode technology, inspired by the original SR-X and the legendary SR-Ω. STAX engineers pursued the ideal balance of low air resistance, minimal reflection and maximum sound permeability, overcoming longstanding challenges surrounding resonance and structural strength. The newly developed diaphragm is 20% larger than the previous flagship SR-009S and uses an ultra-thin engineering film with exceptionally low mass for lightning-fast transient response and extended high-frequency performance. Combined with a precision-machined aluminium enclosure that suppresses unwanted vibration and controls internal reflections, the SR-X9000 produces an expansive soundstage with exceptional clarity, focus and tonal balance.

Handcrafted in Japan

Every aspect of the SR-X9000 has been refined for long-term comfort and uncompromising performance. A redesigned stainless steel arc assembly improves rigidity and stability, while genuine leather head padding and soft sheepskin ear pads provide a luxurious fit with outstanding breathability. The newly engineered guard mesh structure uses staggered pillar lengths to control reflection angles and allow sound waves to move more naturally through the enclosure. Completing the system are detachable high-purity 6NCu and silver-plated copper cables, supplied in both 2.5 metre and 1.5 metre lengths to suit different listening environments. The included paulownia wood storage case offers excellent humidity control and thermal stability, providing the ideal environment to protect the SR-X9000.
