STAX SR-L500 MK2 Review: A New Benchmark in Electrostatic Fidelity
Welcome to our STAX SR-L500 MK2 Review, where we dive deep into the engineering marvel that is the Advanced-Lambda series Earspeaker. Building on the pedigree of its predecessor, the SR-L500 MK2 elevates electrostatic headphone performance with user-friendly refinements, exquisite comfort and a sound signature that will thrill discerning audiophiles.
Ergonomics & Build: Elegance Meets Practicality
The SR-L500 MK2’s aluminium case holders adopt a gentle curve, wrapping around the head with just the right amount of grip. This design improvement over the linear form ensures the artificial leather earpads sit flush against your skull, enhancing both seal and bass extension in this open-air type earspeaker. Weighing in at a mere 351g (479g with cable), you get a supremely light package that invites marathon listening sessions.
Exchangeable Cable Structure: Future-Proof and Serviceable
STAX’s adoption of a high-quality detachable cable system aligns with the modern audiophile trend. The included HiFC conductor assembly boasts low capacitance and wide parallel strands, offering 2.5m of reach. Should you wish to explore boutique cables or require rapid maintenance, the plug-and-play termination makes upgrades and repairs effortless.
Frequency Response: 7Hz – 41kHz; incredible sub-bass extension and hyper-sonic detail
Sensitivity: 101dB SPL @ 580V DC bias; superb dynamics with minimal amplifier load
Impedance: 145kΩ; perfect pairing with dedicated electrostatic headphone amplifiers
Electrostatic Capacitance: 110pF; precise charge distribution for consistent transient response
Sound Signature: Transparency and Depth
In our listening trials, the SR-L500 MK2 displayed a distinctly neutral tonal balance, with micro-detail retrieval that brings recordings to life. Piano timbres possess organic weight, orchestral crescendos bloom with natural reverberation, and high frequencies maintain air and sparkle without fatigue. The open-air design grants an expansive, three-dimensional soundstage, delivering pinpoint imaging and layering that immerses you in the music.
Who Should Consider the SR-L500 MK2?
If you’re an audiophile seeking the clarity of electrostatic transducers and you own—or plan to purchase—a dedicated stat-head amplifier, the SR-L500 MK2 is an outstanding choice. Its ergonomic refinements cater to home listening, mastering suites or late-night headphone sessions. It’s especially compelling for those who prize tonal neutrality, transient agility and a wide dynamic range.
