Our thoughts

A route into STAX's flagship electrostatic lineage, built on the electrode technology that underpins the brand's high-end models. It suits committed listeners who want the core design behind the current range.

MLER, a multi-layer fixed electrode, is made by bonding photo-etched metal plates at atomic level under vacuum. The aim is a flatter electrode with low resonance and high sound wave transmission. A replaceable cable means a broken lead is a swap rather than a repair, and the headphones stay open to higher-grade cables later. The 580V DC bias requires a dedicated electrostatic energiser, so it belongs in the system plan early.

It suits listeners who want to trace STAX's current range back to where it started, and who are ready to add a dedicated energiser. Genuine sheep leather sits against the skin, with artificial leather around the surround. Call the team to talk through energiser pairing and how the replaceable cable fits your setup.

The SR-009, the origin of STAX's current high-end models. Equipped with a large circular sound unit featuring innovative fixed electrodes, this model led the high-end headphone culture for a long time. Production had ceased with the arrival of the new flagship model, but now, in response to numerous requests from fans worldwide, it is making a comeback. With changes to the body colour, cable material, and unit case, it is now available at a more accessible price than at its original launch.

MLER (Multi-Layer Electrode)

The SR-009 (released in 2011) was the catalyst for the current high-end models SR-X9000 and SR-009S. The key technology for high-end models, MLER (Multi-Layer Electrode), originated with this model. Using thermal diffusion bonding technology, which unifies photo-etched metal plates at the atomic level under vacuum conditions, this new fixed electrode achieves exceptional planarity, low resonance, and high sound wave transmission. The SR-009D remains the most affordable option for experiencing the sound of current STAX high-end models.

Replaceable Cable Design

SR-009D adopts the replaceable cable structure, which is now standard across the current lineup. This enhances the usability of the earspeakers by enabling future compatibility with high-quality cables and easy maintenance in case of unexpected cable breakage.
