Welcome to our in-depth STAX - SRE-750H - PC-OCC 5m Extension Cable Review. Audiophiles who demand both distance and fidelity rejoice: STAX’s newly designed low-capacity parallel extension cable allows you to position your earspeakers up to five metres away from your main amplifier without sacrificing detail, dynamics or transparency.

Design and Build Quality

STAX has utilised the same wide-format PC-OCC (Pure Copper – Ohno Continuous Cast) conductors featured in the premium SR-007 “Omega II” and SR-404 Signature earspeakers. The cable’s low-capacitance, parallel configuration minimises inter-conductor coupling, ensuring superior transient response and phase coherence over its full 5m length. A supple yet robust PVC outer jacket provides flexibility for dynamic listening setups, while internal microphonic damping reduces handling noise.

Signal Integrity and Sound Performance

The PC-OCC conductors deliver ultra-pure signal transfer, preserving the delicate micro-detail and timbral accuracy that discerning listeners crave. Expect a transparent midrange, extended high-frequency articulation and a taut, well-controlled bass response. The extension does not introduce undue capacitance loading, maintaining the swift current delivery unique to electrostatic earspeakers. Listeners will appreciate the low noise floor and absence of colouration—even at lower volume settings.

Who Is This Extension Cable For?

Ideal for STAX headphone enthusiasts, home studio professionals and high-end audio connoisseurs alike, the SRE-750H 5m cable offers freedom to roam without compromise.
