STAX SR-007MK2 Reference Earspeaker Review: A New Benchmark in Electrostatic Audio

Our STAX - SR-007MK2 Reference Earspeaker Review unveils a paradigm shift in electrostatic headphone performance. Meticulously engineered by STAX, the SR-007MK2 delivers deep, powerful sound previously unobtainable in earspeakers, while preserving the delicate tonal nuances audiophiles crave.

Design and Build Quality

The SR-007MK2 features an open-air enclosure with genuine lamb leather ear pads for direct-skin comfort, paired with high-grade synthetic surrounds. STAX’s latest innovation is on show with the gold-plated electrode structure, visible through the transparent casing. By eliminating traditional perforations, this design increases diaphragm surface area, combining formidable power with the signature electrostatic delicacy.

Technical Mastery and Sound Performance

At its core, the SR-007MK2 employs a push-pull electrostatic circular sound element, delivering a remarkable frequency range of 6Hz to 41,000Hz. With sensitivity rated at 100dB/100V RMS and a bias voltage of 580V DC, it offers exceptional dynamic range. The low-capacity PC-OCC cable, combined with a total capacitance of 94pF and an impedance of 170kΩ at 10kHz, ensures an uncoloured, precise audio experience. Every microdetail in your recordings is rendered with breathtaking clarity.

Who Should Consider the SR-007MK2?

A perfect partner for audiophiles, sound engineers and those who demand ultimate fidelity. If you’re seeking an expansive soundstage, pinpoint imaging and a headphone that rewards high-end amplification, the SR-007MK2 will not disappoint. Ideal for critical listening and mastering environments where accuracy is paramount.
