STAX - SR-L700 MKII - Advanced-Lambda Series Earspeaker Review
Embark on an audiophile odyssey with our STAX - SR-L700 MKII - Advanced-Lambda series Earspeaker Review. Boasting cutting-edge Multi Layer Electrode (MLER) technology and a refined aluminium case holder, the SR-L700 MKII delivers unparalleled clarity from 7 Hz to 41 kHz. For those seeking reference-grade detail and an expansive soundstage, this electrostatic earspeaker is a revelation.

Design & Comfort Redefined
The SR-L700 MKII adopts a user-centric cable-exchangeable structure, allowing compatibility with high-definition aftermarket cables and effortless maintenance in the event of a disconnection. Complementing this, the aluminium case holder has evolved from a linear to a subtle curved profile, ensuring natural conformity to the head. The result is enhanced adhesion at the back of the skull, which directly translates to tighter, more articulate bass response in an open-air design.

Electrostatic Mastery: MLER & Push-Pull Dynamics
At the heart of the SR-L700 MKII lies a push-pull electrostatic driver with fixed electrode MLER technology. The multi-layer electrode configuration minimises membrane resonance and distortion, while the 580 V DC bias voltage sustains a controlled electrostatic field. With an electrostatic capacitance of 110 pF, 145 kΩ impedance and 101 dB sensitivity, these earspeakers effortlessly resolve the subtlest microdynamics and harmonic overtones.
Sound Signature & Performance Highlights
The SR-L700 MKII unfolds an expansive soundstage that places instruments with pinpoint accuracy. The ultra-low mass diaphragm responds instantaneously to transients, delivering snappy rhythm with exceptional pace and energy. Midrange performance is etched with lifelike tonality—vocals stand centre stage with crystalline clarity, while the upper treble extends beyond 40 kHz, revealing air and ambience that recordings seldom disclose.
Who Will Cherish the SR-L700 MKII?
Enthusiasts who demand a reference-grade transducer for critical listening, mastering or simply indulging in audiophile recordings will find the SR-L700 MKII transformative. Whether you stream high-resolution files or spin analogue vinyl through a suitable energiser, these earspeakers reward scrutiny with nuance and transparency.
