Synergistic Research SRX XL Headphone Cable

Synergistic Research SRX XL Headphone Cable

SRX XL Headphone Cable brings the conductor architecture, shielding, and conditioning developed for Synergistic Research's flagship SRX XL interconnects, speaker cables, and power cords to headphone listening. It uses hand-made air-dielectric pure silver geometries scaled for headphone applications, balancing conductor count and cable flexibility for comfortable extended listening without compromising resolution or dynamics. Every cable uses SRX XL Matrix Shielding with Graphene and is treated with SRX XL High Voltage Conditioning, and ships standard with Gold and Master carbon fiber UEF Tuning Bullets, the same tier used across the SRX series. Built with custom-terminated source connectors (Stereo 3.5mm, 1/4" TRS, Stereo XLR, or Discrete XLR) and a wide range of headphone-side connector options. As an authorized Synergistic Research dealer in Toronto, Canada, Vinyl Sound can help you match this cable to your specific headphone and amplifier.

Tuning Modules

SRX XL Headphone Cable ships with both Gold and Master SR25 UEF Tuning Passive Modules, hand-crafted from carbon fiber and aircraft aluminum and voiced specifically for the SRX series. Both work entirely outside the signal path:

• Gold — greater musicality, liquid smoothness, air and detail
• Master — greater air and detail, musicality, liquid smoothness

Allow the cable to settle into your system for 48-72 hours, then compare Gold and Master and select whichever makes music in your system — the best option is system-dependent.
