Home Theatre Review

At the heart of the SR-007S are newly engineered diaphragms and fixed electrodes that deliver greater resolution, particularly in the higher frequencies. STAX has reduced the size of the electrode air-vent holes by around 20% compared to previous versions, a change that enhances airflow control and reduces resonance, resulting in cleaner, more natural sound reproduction. These improvements bring listeners closer to the recording, capturing micro-details and transient speed with remarkable precision.

The SR-007S also adopts an anti-resonance structure inspired by STAX’s flagship SR-X9000. A seamless stainless steel arc enhances rigidity and minimizes unwanted vibrations, while the redesigned headband includes a movable hinge for better fit and comfort. Acoustic refinements extend to the new earpads, which use soft sheepskin on the contact surface and a more absorbent inner material to reduce reflections. The pads are rotatable, providing a more personalized fit, and feature the series’ traditional brown coloration, linking the design to its heritage.

For practicality, STAX has introduced a detachable low-capacitance, six-strand OFC wide cable, making maintenance and upgrades easier. Technical performance is equally impressive, with a frequency response ranging from 6 Hz to 41 kHz, ensuring both subterranean bass control and airy treble extension. With a sensitivity of 101 dB and a 580 V “Pro” bias requirement, the SR-007S demands a dedicated electrostatic amplifier to reveal its full potential.

Sonically, the SR-007S is designed to deliver a balance of speed, clarity, and musical weight. Listeners can expect a tight, articulate low end, open and extended highs, and a midrange that carries both warmth and precision. These earspeakers are built for long listening sessions, combining luxurious materials with structural refinements that reduce fatigue while maintaining a secure acoustic seal.
