Synergistic Research DC SX Power Cables
Not long ago, people assumed AC cables could have no effect on the sound of a stereo system, and some still believe this to be true. The same holds for audio interconnects and speaker cables, while people who have listened know better. But what about DC? Surly, DC is just DC, right? Wrong. We’ve known for years that DC cables affect the sound of active components like Tranquility Bases and Tranquility PODs.

So, SR set out to build the ultimate DC cable capable of transforming the performance of Active Synergistic Research components with the same newly developed technologies found in the Galileo Discovery and SRX level power cords. SR started with a pure 99.9999% silver monofilament conductor in an air dielectric hand made in SR's California factory and added UEF Technology first developed for SRX level power cords and then applied a long duration high voltage conditioning process also designed for the SRX cable loom. The net result is a DC cable that dramatically improves the audible performance of SR components when spanning between the new UEF Linear Power Supplies and DC-powered Synergistic Research components.

SR even developed a special DC cable voiced for the Roon Nucleus Server and included a UEF Gold Carbon Tuning Disc so you can fine-tune the performance of your Nucleus to match the overall balance of your system.

DC SX Power Cable 2 ft. - $395 - $75 per add. ft.
DC SX Roon Spec Power Cable 2 ft. - $495 - $75 per add. ft.

2 each Silver Air String:

  • Silver Air Strings: 99.9999% pure monocrystal silver conductor
  • 2 separate conductors
  • Dielectric: Air (sealed)
  • UEF Shielding -Quantum Tunneled


  • Gold plated 3.5mm

Build Notes:

  • 4 point-to-point hand soldered connections
  • Atmosphere Level 2 UEF Matrix Shielding: UEF coating with Graphene is applied directly to connectors significantly reducing the noise floor and allowing a purer signal to transfer with less grain providing more warmth and detail
  • Silver Solder: 4%
  • Hand build time: 30 minutes
  • SRX Long duration Quantum Tunneling: Post Production process, 1 million volts are passed through finished cable providing a “canal” that allows electrons to pass more freely through conductor material and connections
  • Secondary UEF Blue Treatment originally developed for SR Blue Fuses
  • Hand crafted in SR's California factory
