SRX XL
Speaker Cables
Building on our development of the SRX XL AC cable almost a year prior, we now apply a similar approach towards SRX XL speaker cables to achieve a new benchmark in performance without compromising SRX XL‘s flexibility. Across the line, we’ve scaled up the number of its internal hand-made air-dielectric pure silver high-current geometries. We’ve added additional pure silver geometries and additional pure silver AirString geometries to be able to offer a new world standard where high conductive pure silver conductors in an air dielectric are concerned. With SRX XL speaker cables, we’ve developed an all-new UEF compound applied it to our matrix shielding, which further lowers each cable’s noise floor while lessening restraints a shield may have on signal transmission. The cables are then run through a further improved high voltage treatment, resulting in cables that sound even more open and accurate than the original SRX. The SRX XL takes SRX’s industry-leading dynamics to a whole new level while also improved nearly all aspects of its performance, including soundstaging, lower noise floor, and increased high-frequency extension with added smoothness.
Discover how transformational the new SRX XL Series is and audition them in your system today. And if you already have a complete loom of SRX series cables in your system, ask your dealer or distributor how you can take advantage of our Lifetime Passport Protection Plan, where you receive a 70% trade-in allowance for your existing SRX series cables toward a new loom of SRX XL series. Of course, you can audition risk-free to gauge the improvements these exceptional cables can affect in your system.

Enhanced Cable Geometries
6N Pure Silver Airstrings, Multiplied
While voicing the SRX XL, we developed more comprehensive cable geometries with additional 99.9995% Pure Silver Air Strings. In doing so, music is portrayed with more immediacy and resolution, improving upon dynamics and transient response in a completely non-fatiguing way.
UEF Matrix Shield with Graphene
SRX XL Matrix Shielding
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
Redefining Refinement
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.
Included (8) Carbon Performance Elevators
Elevate your performance.
UEF Carbon Elevators lift your cables from the floor as they uplift fundamental aspects of system performance, including low-frequency weight and control, mid-range clarity, and high-frequency extension. Perhaps most dramatic is the effect on your system’s ability to portray soundstage scale with improvements in front to back, side to side, and verticle image placement, all with a greater sense of the sound field wrapping around your listening position. Our first cable elevators were made from aluminum after extensive double-blind listening tests, where aluminum exhibited superior sound quality compared to materials like plexiglass, wood, and ceramic. The one material we did not test was Carbon Fiber due to its difficulty to cut and fabricate. Fast forward two years, and we have perfected the use of carbon fiber in SR products, including our state-of-the-art SRX cable loom, Galileo Active Ground Block, Active Ethernet Switch, and MiG SX footers. So we built a set of carbon fiber elevators and compared them to our Aluminum cable risers. We found the same improvements as all SR products using carbon fiber, namely, increased resolution, inner detail, and clarity. The included HFT’s (Red Dot visible in photographs) use a new UEF compound first developed for SRX speaker cables interact with your cables EM fields for life like soundstage scale with enhanced dynamics and high-frequency extension.

SRX Cable Series Reviews
[They are] exceedingly realistic sounding, capable (with the best sources) of fooling you into thinking you are in the presence of actual musicians. Not only do they reproduce timbre with lifelike density; they also reproduce the dynamic/harmonic envelope (from starting transient through steady-state tone to decay) with lifelike duration, without adding, for instance, “zip” or ringing to hard transients, sibilance to frictatives of higher pitch or amplitude, or smearing to decays. This is the very essence of “completeness”—and the reason why you can not just readily visualize singers like Sinatra on Sinatra at the Sands through both wires; you can also tell the way he is using his mic (like that geisha fan he compared it to) to shape, punctuate, and convey the emotional power of his delivery.
[They] are superb imagers and soundstagers; [they] reproduce the dynamic range of recordings with high accuracy; [they] are astonishingly realistic sounding with great tapes, LPs, and streams; and both lower noises and colorations to unprecedented levels.
So…where does that leave you?
Well, to begin with you’ve got to be rich to afford either one of these extraordinary looms of wire. However, for what it is worth, SRX is a good deal less expensive than Da Vinci (e.g., an eight-foot pair of SRX speaker cable costs $29,995; a two-meter pair of Da Vinci speaker cable is a staggering $46,500). If a $16.5k difference means anything to you (and if it doesn’t, my congratulations), then I’d certainly opt for the SRX.
Jonathan Valin, The Absolute Sound, Jan 2023
Once connected to my Powercell and burned in for just over a week, I sat down and listened to my standard digital file set list for an initial evaluation. I have been using this group of tracks for well over five years and without much change. Typically, I bounce through the first dozen or so just to get a feel for what to expect. This time, I was immediately locked into each track from beginning to end and without interruption for several hours of listening. I cannot remember this ever happening before.
Why? Well, I could talk about the deeper blacker noise floor, the expansion of the sound stage in all directions, the holographic pinpoint imaging, and the rich full bodied textures, but there was something so fundamentally different with the SRX in place that I could just not skip through the music as usual"
....The Synergistic Research SRX power cord has me rethinking my entire system configuration and performance. When only one SRX power cord was used with the Synergistic Research PowerCell 12 UEF SE power conditioner to drive my entire system there was a clear correctness of presentation that had not previously been realized. I can only imagine what might happen if I used the SRX for all my components! Caveat emptor. Never say never. If you audition the SRX, you may never go back.
Robert Youman, Positive Feedback, August 2019
Synergistic Research’s complex and difficult-to-manufacture SR25 Limited Edition power cord so stunningly demonstrates the relationship between high-quality power and high-quality sound that it may represent the apotheosis of power-cord design. When I said that the SR25 transformed virtually every aspect of my system’s sound, I wasn’t exaggerating. It was difficult to believe that these improvements were caused by a single power cord, or that my system already contained a high-end power conditioner and cords. Once again, Ted Denney has proven that the simplest circuit is not necessarily the best sounding. Twenty large -- enough to buy a new Honda Civic -- is a very great deal to pay for a power cord, and most can’t pay it at all. The audiophile masses will take solace in the technologies that I hope will eventually trickle down from the SR25.
Can a $20,000 power cord constitute a bargain? It
