The PowerCell 12 UEF SE is more than your next generation power conditioner; it’s the heart of your audio system. With 10-gauge silver matrix point-to-point wiring and separate EM Cell filtration banks for the ultimate in component to component isolation and peak current delivery, 6 UEF Black Duplexes, and utilizing graphene, a near superconductor at room temperature, the PowerCell 12 UEF SE provides the purest and cleanest form of non-current-limiting power possible from today’s cutting edge components. Simply plug your entire system into the PowerCell 12 UEF SE to dramatically improve all areas of sound quality, guaranteed.

Generating absolutely no heat or noise the PowerCell 12 UEF SE is perfect for all types of electronics including power-hungry mono block amplifiers. And with two separate Active EM Cell power banks feeding 6 UEF Black Duplexes each isolated one from another through direct 10-gauge silver matrix point-to-point wiring, your PowerCell 12 UEF SE isolates digital from analog components better than any other PowerCell line conditioner. Of course, this flagship model comes standard with the High Current Atmosphere Level 3 Active power cable and can be custom ordered with a High Current Galileo UEF power cord for the ultimate sound quality upgrade.

The PowerCell 12 UEF starts with a high carbon steel chassis treated with a UEF coating that blocks EM and RF interference and is designed to function as a superlative conduit for our new Ground Plane Technology.

Developed exclusively for the PowerCell 12 UEF, the ULF (Ultra Low Frequency) Field Generator connects directly to the PowerCell 12’s six duplexes through the six Active EM Cells. It’s designed to clean your electric power by re-clocking the mains with a rich, low-frequency harmonic that overrides noise and hash found in most common 50-60 cycle AC.

Six separate UEF electromagnetic cells with graphene, act like supercapacitors to increase peak current on demand, allowing your components to draw more power than they would normally when connected to the wall. This gives your system added dynamic headroom while filtering the AC, all completely outside the signal path.

The new PowerCell 12 UEF SE AC Line Conditioner is the culmination of 10 years of research into electromagnetic cell design starting with the first EM Cell prototype in 2007. EM Cells act to condition alternating current through the inductive coupling of differential EM fields and AC for an AC power conditioner that is entirely non-current limiting. The electromagnetic cells in your PowerCell 12 UEF SE operate in ways similar to a hydrogen cell, hence the name PowerCell, however, instead of a chemical reaction, an inductive coupling takes place between the plates. The effect of this reaction drastically reduces reactive capacitance in the AC signal transfer, preventing phase anomalies with a total absence of noise on the AC line.

The six Electromagnetic Cells provide two stages of filtration: one large 640 cm² “flat” cell covering all 12 outlets, and five 819 cm² ”folded” cells shielded and housed in carbon fiber cylinders. Four of the folded cells cover the six duplex outlets’ mains (or 2 cells each per three duplexes). The fifth folded cell covers the current’s ground plane system-wide. This new configuration makes it possible for the PowerCell 12 UEF SE to provide twice the filtration area of the outgoing PowerCell 10 UEF.

Altering the shape of the EM cells changes their inductance properties and thus their sound quality. Flat EM cells subjectively increase sound-staging air and liquidity while folded EM cells enhance detail, dynamics, and focus. Using both types of cells in unison gives your system the best attributes of both folded and flat EM Cells.

Further, the EM Cells now contain graphene, a new highly conductive wonder material that consists of a single layer of pure carbon only a single atom thick. One of the many reasons that graphene is so exciting is that it is almost a superconductor at room temperature. Superconductors are materials that can conduct electricity with almost no resistance when cooled to extremely low temperatures ranging from near absolute zero (-459.67°F or -273.15°C) to the temperature of liquid nitrogen (-140.8°F or -96°C). What makes graphene so remarkable is that it can do this at room temperature.

The circuit board provides the foundation for the power that drives the EM Cells and ULF Field Generator, while Synergistic Power Transformers and Quantum Capacitors generate the purest electricity possible.

The highly conductive 62 cm² 99.995% pure silver Ground Strap is UEF treated and features graphene for ground filtration borrowed from our award-winning SR Ground Block. In fact this pure silver Ground Strap is attached to each of the six SR Black AC Outlet to star ground your entire system when components are plugged into the PowerCell 12 UEF. Star grounding with UEF filtration reduces series inductance in the ground path for a noticeable improvement in sound quality over traditional grounding options.

The term “ground” refers to a connection to the earth which acts as a reservoir charge. The highly conductive pure silver Ground Strap provides a conductive path for ground separate from the normal current-carrying path of your components which under certain conditions can add up to 10 dB of noise. The ground path with the least resistance is the best path to Earth and there is no better ground path than the PowerCell 12 UEF’s pure silver Ground Strap.

Plug up to twelve components into six of our highest performance Black UEF Duplex outlets (retail $250 each!), which were developed with the same technology found in our Black UEF Fuses and deliver similar benefits of a lower noise floor with improved frequency extension and sound staging. To further improve the quality of your analog and digital component’s performance, the six Black UEF Duplexes are divided into two banks, eliminating cross talk between components, for the ultimate in component to component isolation.


SR  Powercell 12 UEF SE AC Conditioner - the best we've heard! by Bill Wells and Clement Perry @
Bell Wells: "With the Synergistic Research PC12 UEF SE power conditioner, I was able to experience magical moments whenever I listened to my system. In fact, at no time throughout my time with this unit did I experience any sort of variation or degradation in the sound that I would attribute to changing AC quality. In fact – it was all good."
Clement Perry: "As it stands, the SR PowerCell 12 UEF SE is the finest AC conditioner to have graced my listening space. I could not recommend this product more highly and easily my 2018 Publisher’s Choice, Most Wanted Component!"

Synergistic Research PowerCell 12 UEF SE Power Conditioner by Steven @ 
"The Synergistic Research PowerCell 12 UEF SE is the quietest and most transparent power conditioner we’ve ever heard. As a consequence, micro/macro details are in full view without losing cohesion, texture, and body. You basically hear more of the music without losing musicality. It provided a new level of clarity, insight, dynamics, and authority while being smooth and euphoric. It is simply an enthralling piece of gear, inside and out."

Synergistic Research PowerCell 12 UEF SE Power Conditioner by Robert S. Youman @
"Synergistic Research has another winner with the PowerCell 12 UEF SE. I was pleasantly surprised if not astonished at the improvement in sound quality over my past benchmark—the excellent PowerCell 10 UEF. Unlike other power conditioners that I have auditioned, the PowerCell 12 UEF SE never feels like it throttles or diminishes the music. Yes, we have superior levels of isolation which results in an impressive reduction in the noise floor, but all the excitement and dynamic contrast of the recording as originally intended is still laid out for all to hear. This one will not be leaving my listening room."
