Network audio streaming introduces challenges beyond traditional digital transmission—managing packet-based data flow while isolating your audio signal from the electromagnetic contamination inherent in routers, modems, and network switches. Building on our flagship SRX XL technologies, the SRX XL Ethernet cable conquers these network complexities with revolutionary engineering specifically designed for high-performance audio streaming applications. Our all-new UEF compound applied to advanced matrix shielding provides exceptional isolation from network infrastructure noise while refined pure silver conductor geometries ensure pristine packet integrity across longer cable runs and multiple connection points. We’ve optimized the hand-made air-dielectric pure silver conductors with strategic spacing that maintains signal clarity through the bidirectional communication demands of modern streaming, preserving timing accuracy and eliminating the data errors that compromise musical reproduction. The SRX XL Ethernet doesn’t just connect your streamer to your network—it creates a dedicated pathway for musical information to flow uncontaminated from source to destination. Every cable undergoes our enhanced high voltage conditioning process, delivering network audio with unprecedented clarity and freedom from the noise artifacts that plague standard Ethernet connections. As the perfect companion to our Network Switch UEF and Ethernet Switch UEF Mk II, the SRX XL Ethernet completes a holistic approach to network audio optimization. The result is streaming audio that reveals the full potential of high-resolution services and your digital library while eliminating network-induced jitter, noise, and timing errors, unlocking new levels of dynamics, soundstaging, and musical authenticity that brings network audio streaming to new heights of analog-like realism. Whether streaming from Tidal, Qobuz, or your personal server, experience how this cable unlocks the musical truth within your network audio sources.

SRX XL UEF Matrix Shielding with Graphene

In our journey to design our latest flagship SRX XL series, we developed an entirely new UEF compound to elevate the performance of our previous Matrix Shielding, which further lowers each cable’s noise floor while lessening restraints a shield may have on signal transmission. We apply this highest level of shielding to our new SRX XL cables for a significant jump in performance over the standard SX. SRX and Master Tuning Bullets developed for the SRX series cables further refines and enhances the loom’s ability to cancel noise that would otherwise cause high frequencies to sound harsh or fatiguing.

SRX + Master Carbon Cable Tuning Modules

SRX XL cables come standard with the most potent and musical SRX Master and Gold carbon fiber UEF Tuning Bullets in our company’s 30-year history. The bullets are specially voiced for the SRX cable series so you can strike the perfect balance between detail and musicality for your system. Both Gold and Master bullets are handcrafted in our Southern California Factory from carbon fiber and aircraft aluminum, with the Gold bullet plated in 24k gold not only for aesthetic beauty but also to help voice the bullet to its intended role as the most musical option for specific systems. To use SRX Carbon Fiber Tuning Modules, allow your SRX cables to settle into your system for 48-72 hours, and then experiment with your two options on a cable by cable basis. Start by inserting a Gold Bullet and then compare to the Master option and select the variant that makes music in your system. Gold Bullets have a warm and liquid balance that is also more open and transparent than our other warm-biased tuning bullets. While Master is more extended and detailed but the option that will work best and sound neutral is totally system dependent. If you voice your SRX cables one pair at a time, you will find one color that works best in most applications, plus a few that perform better with the alternate option. This process is how you will get the best from both Gold and Master bullets when arriving at a bespoke cable loom voiced for your unique system. Note, UEF Tuning Bullets work 100% outside the signal path!

SRX XL High Voltage Conditioning

The new SRX XL High Voltage Conditioning is our most advanced process for treating cables with 1,000,000 volts of electricity at specific frequencies and pulse modulations for long durations, creating a canal in the conductor material and contact points at the molecular level that allows electrons to flow more freely. This new process improves upon the SRX High Voltage Conditioning process by employing new extended duration sweeping frequency plots and advancements to our Tesla Coil, resulting in SRX XL cables to sound even more open and accurate than the cables before them.

UEF Ground Plane

SRX XL Ethernet incorporates the capability to ground your cables to a Synergistic Research Ground Block (sold separately) to elevate the performance even further. Benefits include a noticeable increase in deep bass power and weight, a more holographic sound field, smoother high frequencies with greater extension and ‘air’, a more present and layered mid-range, increased tonal density with an apparent increase in resolution.
