In this STAX SRE-950S PC-OCC 5m Silver Plated Extension Cable Review, we explore how STAX’s flagship extension lead refines your headphone setup with industry-leading materials and sonic transparency. Our audiophile team at The Audio Tailor has put these 5 metres of silver-coated, ultra-pure OCC copper through rigorous listening and technical appraisal — and the results are compelling.

Overview

The STAX SRE-950S PC-OCC 5m Silver Plated Extension Cable is engineered for discerning headphone enthusiasts who demand the ultimate in signal purity and mechanical reliability. Utilising 6N (99.9999%) pure copper conductors with a precision silver-plated finish, the cable structure minimises signal attenuation, reduces capacitance and preserves the fast transient response STAX electrostatic headphones are renowned for.

Design & Build Quality

• OCC Copper Core: Single-crystal high-purity copper for minimal grain boundaries and outstanding conductivity.
• Silver Plating: 99.99% pure silver layer delivers improved high-frequency extension and microdetail retrieval.
• Optimised Geometry: Balanced conductor arrangement reduces crosstalk and maintains channel separation over long runs.
• Durable Jacket & Strain Relief: Flexible yet robust outer sheath with reinforced connectors prevents microphonics and wear.

Mechanically, the SRE-950S feels rock-solid yet supple, allowing easy routing in a studio or listening room without kinks. Precision-machined connectors ensure a secure, low-resistance interface with your STAX headphone earcups.

Sound Quality Enhancements

Compared to a standard PVC-insulated cable, the STAX SRE-950S exhibits remarkable improvements:
• Enhanced Clarity: Silver plating improves detail retrieval in the treble spectrum, revealing nuances in cymbals and string harmonics.
• Improved Dynamics: The low DCR (DC resistance) and reduced skin effect maintain punchy transients and bass articulation.
• Wider Soundstage: Superior channel separation and minimal dielectric absorption facilitate a more spacious, three-dimensional soundfield.
• Reduced Noise Floor: High-purity conductors and precise shielding keep hiss and interference below perceptible thresholds.

Whether you’re tracking mixing sessions or savouring a hi-res jazz master, you’ll notice an immediate lift in transparency and tonal accuracy.

Who Should Consider the STAX SRE-950S?

This extension cable is a perfect match for existing STAX SR, SRS and SRM headphone systems in studios, high-end listening rooms or broadcast suites. It’s tailored to:

• Pro audio engineers seeking an uncompromised signal path in critical listening environments.
• Audiophiles aiming to extract every last detail from electrostatic headphone rigs.
• Home theatre and gaming enthusiasts who want freedom of movement without sacrificing sonic fidelity.
