Atmosphere Series Power Cables

Level 2

To exceed the astonishingly high performance of our award winning "Actively Shielded" AC power cables of the past without cumbersome external MPC wall wart power supplies and messy wires, we had to redesign the entire concept. Focusing on a smaller, more efficient and more powerful internal DC power supply to bias the Copper Matrix, Tricon and Silver/Tungsten "Air String" geometries, not only did we make it better, we made it easier to use. Atmosphere Level 2 AC Power Cables are the first Active Shielded power cords in the Atmosphere line up. Redesigned for greater performance, more flexibility and significantly easier to use than our previous Active power cords, Atmosphere Level 2 boasts the first ever onboard, UEF treated, "Active Shielding" power supply, delivering increased macro and micro dynamics by significantly lowering the noise floor of connected components and all with no messy wires or wall wart power supplies. Simply plug and play like standard nonactive cables. Starting with the same Gen 4 Tricon, Copper Matrix and high current AC current geometry of Atmosphere Level 1 but with an additional Silver Air String the performance is ramped up substantially, expanding your components ability to unravel low-level information. Air and sound staging, height and depth, layering and focus are all dramatically improved by Active Shielding as well as the addition of an extra AirString geometry.

Atmosphere Level 2 Power Cables contains a power supply that generates the 30 Volt DC bias necessary for Active Shielding, eliminating the need for messy external wiring and cumbersome wall warts. Performance is further enhanced by the introduction of UEF technology built into the power supply and cable shielding for an incredibly low noise floor. 


Red Active Tuning Circuit

Redefining refinement.

Learn more about the Tuning Circuit

The Atmosphere Level 2 power cords active shielding is voiced with a single, included, Red UEF Tuning Circuit.  The UEF Tuning Circuit is connected to the cable shields and contour the sound of your cables by changing the way your cables resonate. By altering the resonance between signal and ground conductors you take control of the sonic balance of your cables and in the process, the overall sound of your system.

The Red Active Tuning Circuit completes the Active circuit and must be in place in order to achieve the highest performance.

Build Notes:

  • 26 point-to-point hand soldered connections
  • Atmsophere UEF 3 Teatment: 2 different UEF coatings with Graphene are applied to Active S Cell, connectors and cabling and ground significantly reducing the noise floor and allowing a purer signal to transfer with less grain providing more warmth and detail. The conductors and ground plane and UEF Cell also benefit from dampening effect that UEF provides
  • 1 Termination for Atmosphere Active Tuning Module (Red)
  • Silver Solder: 4%
  • Hand build time: 2.5 hours
  • Quantum Tunneling: Before the Active power supply is incorporated all connections and cabling are treated with 1,000,000 volts of electricity at specific frequencies and pulse modulations, creating a canal in the conductor material and contact points at the molecular level that lets electrons to flow more freely. This allows the "Active Shielding" to work more efficiently yielding the maximum amount of low level information through the conductors and provides for the higher degree of realistic musical performance
  • 5 day Burn-in: 2 step process
  • Hand crafted in our California factory


    Based on my experience, the newer Atmosphere Euphoria SX cable series improves upon the already outstanding series, not in any subtle way. These newer cables represent the evolving innovation and technological improvements from a company continually exploring ways to improve its current success.

    At some point, later in life, we acquire fine components, realizing that they will become our "forever" amp or loudspeaker. The Excite SX cables qualify for that status for me. I wish I had reached this level a decade ago. But in the case of Synergistic Research cables, who can really say "forever"? Ted Denney and Synergistic Research are showing no signs of slowing down their creativity or technological innovation.

    "The Synergistic Research Atmosphere X Euphoria cables are nothing short of compelling. They strike the perfect balance of smooth, full, and resolving. It’s a mesmerizing sound that will keep you in your seat – listening for hours upon hours. It sure did for me."

    "The Synergistic Research Atmosphere X Euphoria (Level 3) interconnects and speaker cables, along with the Atmosphere UEF (Level 3) power cables, have rekindled my passion for the very best in sound and performance. I had not realized that there was so much more musical information available that could transform my system well beyond flavor or personality."

    "Finally, moving on to the Euphoria Level 3, and once again I heard more of the same. I made out a firmer bass line and more articulate piano playing. The decay of the notes seemed more evident, and overall the sound had noticeably greater subtlety, finesse, and delicacy. There was something more, as I felt more drawn into the music."

    “By far the quietest power cord I’ve ever encountered.”


    “First, compared to the Elements, the Atmospheres had a naturally warmer, more organic, and harmonically fuller sound that lacked the older cables’ relatively sharp edges.”


    "Synergistic Research cables and devices, was absolutely thrilling, with tremendous dynamic impact, presence, and detail"


    "The Synergistic Research set of cables are expansive in all three dimensions, revealing with resolution and raw details, incredibly quiet in its noise floor with a lot of bass extension in treble energy."

    “I just couldn’t find a flaw in the SR Atmosphere speaker cables”


    "Once you have heard the difference these speaker cables can make to your system, you cannot un-hear it"


    “Better sound for less money from the same manufacturer? My goodness, how often does this happen?”


    "I wouldn't have believed they could have made such a difference. Combining the two, there is not much sonic distance between my system now, and those costing hundreds of thousands of dollars"
