DC SX Power Cables

Direct to the point


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 we 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 our Galileo Discovery and SRX level power cords. We start with a pure 99.9999% silver monofilament conductor in an air dielectric hand made in our California factory and add UEF Technology first developed for SRX level power cords and then apply 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 our new UEF Linear Power Supplies and DC-powered Synergistic Research components. We even developed a special DC cable voiced for the Roon Nucleus Server, and we 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.

UEF Matrix Shield with Graphene

Matrix shielding.

The previous Atmosphere X Series Cables started as an experiment to explore ways of improving UEF Shielding by placing UEF Tech at strategic grid points on the shields of Atmosphere cables, now called Matrix Shielding. Matrix Shielding arranges UEF elements on a grid pattern of the cable shield to lower its noise floor. Atmosphere SX refines Matrix Shielding further by using new Carbon Fibre UEF Tuning Discs developed expressly for Atmosphere SX to enhance the loom's ability to cancel noise that would otherwise cause high frequencies to sound harsh or fatiguing. As a result of our ongoing research into UEF Shielding, we have pushed the resolution envelope when voicing Atmosphere SX by developing new Carbon Fibre UEF Tuning Discs for a more holographic sound with enhanced resolution and musicality.


Quantum Tunneling

SRX Long Duration High Voltage Conditioning.

After perfecting the most natural-sounding and holographic cables in our history, we set out to take them further with a new high voltage conditioning process that applies a sweeping frequency plot for an extended duration. We experimented with dozens of frequencies in different combinations over a prolonged time period before landing on just the right mix. We even built a new Tesla Coil to handle the excess heat generated during long conditioning sessions. Once finalized, the SRX conditioning process created holographic realism and timbrel accuracy far beyond our previous Tesla Coil conditioning protocol.

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 2.5mm

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 Fusess
  • Hand crafted in our California factory
