Never Compromise

The technology for the new Synergistic Research SRX power cord was taken directly from the SR25 25th Anniversary power cord that was limited to 100 pieces worldwide. The SRX is an exact duplicate of the now sold-out SR25 with one exception, a different grade of pure six-nines silver is used, and this cuts the cost of this reference power cord in half. Each SRX power cord is fabricated by hand in the California factory, including a flexible pure silver signal path ribbon laminate that acts as an Electromagnetic Cell running the full length of the cable from the wall plug to the IEC. Additional AC conductors are made from pure six-nines silver in an Air Dielectric for a total of nine gauge of pure silver each for the hot and neutral run.

In every respect, the SRX represents the zenith of what SR currently knows on building the world’s state-of-the-art power cord. SR technologies include the most advanced UEF shielding ever developed for a power cord and the most complex dual folded electromagnetic cells placed in a power cord made from pure six nines silver for both the hot and neutral AC leg. With a long flexible flat EM Cell and two folded EM Cells all made from pure six-nines silver, you have in effect a pure silver PowerCell line conditioner in an AC cable format.

Additional SR25 technologies include a pure silver Ground Plane that can be connected to Active Ground Block, SE or Galileo SX for a lower noise floor and added holographic sound staging and dynamic impact and a Swiss Made power supply developed to optimize the pure silver EM Cells. SRX has the exact same wall and IEC connectors developed for the SR25 made from Carbon Fiber and special Rhodium contacts selected in blind listening tests for their perfect sonic balance within the sound of the cable itself. Each SRX power cord comes with two carbon fiber UEF Tuning Modules specially voiced for the SRX so you can strike the perfect balance between detail and musicality for your system. To voice SRX to your system listen to the Gold (warm) and the Silver (detail) bullet and select the option that makes music in your system. Needless to say, this is the most holographic, lowest noise floor and dynamic and musical power cord in our line-up. This power cord is exceptionally well suited for use with our PowerCell 12SE line conditioner as just one SRX can improve the performance of your PowerCell and this improves every connected component in your system. 

Now with Master Tuning Modules (€935/pair MSRP). SRX Cables come standard with the most potent and musical UEF Tuning Bullets in SR 30-year company history and work 100 % outside the signal path. Both Gold and Silver bullets are handcrafted in their Southern California Factory from carbon fiber and aircraft aluminum with the Gold option 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 Silver 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 Silver 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 Silver bullets when arriving at a bespoke cable loom voiced for your unique system.

A Cable…and a Power Conditioner (without the traditional disadvantages!)

Synergistic Research SRX AC by Cestina @
"No matter how hard did I try, the results of using the Synergistic Research SRX power cable were consistently phenomenal. Always improvements, no tradeoffs. I am wondering why there is such a performance gap between the already great Synergistic Research Galileo SX power cable, and the SRX. At least in my system, these two were completely different animals. If the SRX is a sabre-tooth lion, the other power cords (including the SR’s own) are more like all other cats to it. Yes, there is a lot of variety and beauty too, but there is only one real predator. The SRX."

Synergistic Research SRX Speaker Cables, Interconnects, and Power Cords review by Jonathan Valin @
"...SRX is anything like “thin” sounding; it is not. Indeed, its bass and power-range timbre are downright gorgeous; its focus and grip in the bottom octaves may even be very slightly higher than that of the Crystal Cable. As a result, details about Fender guitar performance-technique—picking, fingering, plucking, and slapping—are (sometimes) a bit clearer."

Synergistic Research SR25 Limited Edition Power Cord byHoward Kneller @
"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. "
"Can a $20,000 power cord constitute a bargain? It can, if it delivers a greater improvement in sound than you’d get from spending an extra $20,000 on, say, a six-figure power amp.

Synergistic Research SRX Power Cord and Galileo SX Ethernet Cable by Robert S. Youman @ posi+ive feedback
"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."
"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."
