PowerCell SX

The evolution of revolution.

PowerCell SX borrows its technology from the now sold out Galileo SX PowerCell for higher performance than PowerCell 12. Technological innovation starts with the Galileo SX PowerCell’s more densely rolled Active Electromagnetic Cells for enhanced filtration and a lower noise floor. PowerCell SX then gets the Galileo SX’s power supply and Schumann Resonance Generator to power and bias its six internal EM Cells. And just like the Galileo SX PowerCell that biased all Active EM Cells, PowerCell SX’s Schumann Resonance generator biases its six Active EM cells, both rolled and flat. In contrast, the standard PowerCell 12 only biases the single flat EM Cell and with a less powerful field generator. Other improvements include the same ground filtration topology as found on the Galileo SX PowerCell for lower noise and a more holographic soundstage, and a unique ability to ground PowerCell SX to a Synergistic Research Active Ground Block for even higher performance without sacrificing any of your twelve AC outlets. And new to PowerCell SX are Orange Capacitors with Orange Fuse technology used in the power supply and field generator offering benefits over both the Galileo SX PowerCell and PowerCell 12. There’s even an Amp Meter that allows you to view the beautiful hand-built circuit as you monitor your system’s energy consumption.

What’s inside?

We transferred over 80% of the technology and improvements first developed for our world-beating Galileo SX PowerCell line conditioner directly into the new PowerCell SX. We then added Orange Capacitors to its power supply and ULF field generator and our new Orange Duplexes to improve PowerCell SX performance. All Active EM Cells are larger and more densely packed with 25% more surface area than the PowerCell 12’s rolled EM Cells for an increase in EM Cell efficiency and enhanced energy storage for power delivery and percieved dynamic range.

At the heart of the PowerCell SX is the Galileo SX’s power supply for biasing all six of its internal Active EM Cells, and we incorporated the Galileo SX’s Ground Plane for a dramatic drop in your system’s noise floor. Lessons learned from the Galileo SX PowerCell development program include the same harmonic of the Earth’s Schumann resonance first determined in double-blind testing to deliver greater detail and holographic realism over the PC 12 SE’s original bias frequency. Additionally, the new power supply and field generator first developed for Galileo SX biases all six Active EM Cells. In contrast, the PowerCell 12 SE only biases its single flat Active EM Cell with the Earth’s Schumann Resonance for a fundamental transformation over PowerCell 12 SE.

Ground filtration is enhanced through the use of a new wiring topology developed for Galileo SX PowerCell to lower a system’s noise floor. Optionally, the PowerCell SX can be connected to our Active Ground Block through a new dedicated ground connection that lowers its noise floor further still and without sacrificing any of its 12 AC outlets. A very useful feature for systems that require all twelve AC outlets.

And PowerCell SX has the wow factor covered with a front amp meter that displays the amperage delivered to your system as it allows you to see the beautiful hand-built circuit inside and an additional large view window on the top will enable you to enjoy its American hand made craftsmanship. You can even change the color and intensity of the light that illuminates both the front amp meter and a top view window. Select between Galileo White, Dante Red, Synergistic Research Blue, and McIntosh Blue to match its lighting to other components in your system. And if you prefer no light at all you can choose to be boring, it’s all up to you.

Galileo SX PCB and  24k Gold Tuning Modules

PowerCell SX takes its power supply, and ULF Field Generator directly from the Galileo SX PowerCell for an improvement in performance at its heart. It also utilizes Galileo SX’s 24k Gold UEF tuning circuits for harmonic richness and enhanced musicality.

25% Larger Folded EM Cells now biased with the Earth’s Schuman Resonance

The five-carbon fiber tubes you see in the PowerCell SX are folded Active Electromagnetic Cells, and these cells are 25% denser than the PowerCell 12 SE’s folded EM Cells; this means greater filtration for a lower noise floor and enhanced dynamics. We also bias all 5 folded EM Cells plus the flat EM Cell visible as a black rectangle with two silver stripes with a harmonic of the Earth’s Schuman Resonance to the PowerCell 12 SE that only biases the single flat EM Cell. 25% more filtration combined with biasing all six EM Cells improves your system’s ability to soundstage over the already excellent soundstaging of the PowerCell 12 SE.

UEF Purple Duplexes

Exclusive to the PowerCell SX is our new isolated ground UEF Purple Duplexes that recieve a full Purple Fuse treatment, including SRX long-duration, High-voltage Quantum Tunneling and UEF Treatment.

Galileo SX Grounding

The internal Galileo SX power supply and ULF Generator included in the PowerCell SX are further enhanced with a UEF Groundplane first developed for the Galileo SX PowerCell to lower the noise floor and increase soundstaging. And to take this performance to a higher level still there is the option to ground the PowerCell SX to one of our Active Ground Blocks which surprisingly improves low-frequency weight and attack as it lowers the noise floor further still without sacrificing one of the duplexes, so you have the full 12 outlets to filter all components in your system without loss of current.

Ammeter with 13 Lighting options

PowerCell SX has the wow factor covered with a forward-facing amp meter that displays the amperage running through your PowerCell as it provides a window to the beautiful hand-crafted circuit inside— combined with a second larger top-mounted window you enjoy viewing the pinnacle of our American craftsmanship. You can even change the color and intensity of the light that illuminates both the front amp meter and a top circuit view window. Select between Galileo White, Synergistic Research Blue, Dante Red, and McIntosh Blue to match its lighting to the other components in your system. And if you prefer no light at all you can choose to be boring, it’s all up to you.

Synergistic Research PowerCell Reviews

Review

"Will the internal struggle to reach nirvana ever end? Probably not. As much as we like to complain about the journey, this is what provides much of the joy and interest in this hobby. The PowerCell SX has the ability to get us amazingly closer and without major upgrades to the rest of the system—closer than any other cable or power conditioner that I have heard in my listening room. The PowerCell SX clearly pushes the envelope. It's only July, but I now have my first nomination for the annual Positive Feedback Writers' Choice Awards. Highly, highly recommended!"

Robert Youman, Positive Feedback, July 2020

Review

"The PowerCell SX on its own does a lot for a system. Sure, it has the 'none more black' dark backgrounds and low noise presentation found in many good conditioners, and it leaves the sound in a good dynamic and rhythmic place, as befits some of the best in 'best for conditioners and filters. The 'first, do no harm' maxim is honoured surprisingly infrequently with power products, as many lean out the dynamic shading as they clean up power chow. The non-current-limiting PowerCell SX is one of the rare exceptions, and for that alone, it gets into the top tier and deserves high praise."

Alan Sircom, Hifi+, November 2023

Full Review

"An overview of Synergistic Research's product line will find something from a continuum of 'mild' to 'wild'. The divide is probably most noticeable between products in the signal chain – like the PowerCell SX tested here – and those outside (like the brand's Acoustic Dots). In fact, if you dig a little deeper, they are all part of the same developmental Unified Energy Field concept, and those who 'get' Synergistic Research will just counter that some struggle to intuit the company's whole systemic concept and just stay with the parts connected to the hardware. There are a lot of parallels between Synergistic Research and those making an ever-more intricate system approach to sound reproduction; it's that Synergistic Research goes deeper down the rabbit hole than most.

The PowerCell SX power conditioner features conditioning and filtration technologies drawn down from the company's no-longer-available flagship Galileo SX PowerCell. This means six active electromagnetic cells fed by the Galileo SX's power supply. These cells are improved over previous editions (trickle-down from the Galileo SX once again) and are a good source of power filtration (almost four times beefier than its predecessor) and EMI/RFI suppression.

That's not all If filtration, interference suppression and the consequent noise floor lowering were the only roles allocated to the PowerCell SX, it would still be relevant. But this is just the start. However, things get a little more 'out there' in Synergistic Research's classic style after this. First, it uses the company's Orange Capacitors and Purple Duplex power inlets. Then it adds field generators, bringing the PowerCell SX in line with the company's other UEF-based line. However, 24k Gold UEF circuits are drawn from the Galileo SX this time. That brings a next-gen level of fine-tuning to the PowerCell SX.

From here, the PowerCell SX adds a Schumann Resonance Generator to power and bias its active EM cells. A who in the what now? Schumann Resonances are low-frequency electromagnetic waves, caused by lightning discharges creating resonance between the surface of the earth and the ionosphere. Estimates say there are about 2,000 thunderstorms on Earth at any moment, and the EM resonance they create makes a set of spectrum peaks at 7.83Hz, with harmonics up to 33.8Hz. This Schumann Resonance has been dubbed the Earth's 'heartbeat', and the frequency is also generated in the PowerCell SX.

There is also provision to ground the PowerCell SX to a Synergistic Research Active Ground Block without using a power outlet. You also get a back-lit, semi-transparent power meter on the front panel. This is similar to the Ghost Meters used by Audio Research, but this one lacks the glowing tubes behind the glass. Still, it looks great!

Determining whether using the Schumann Resonance Generator and the like adds anything tangible beyond the PowerCell SX's intrinsic performance as a good conditioner is a bit of a tough call. If you get what Synergistic Research does, these are core elements in building a superior-sounding system. You'll know then, that the PowerCell SX and all its component parts result from extensive blind listening tests by Ted Denney and the Synergistic Research team. As a result, you'll consider the PowerCell SX as a core part of a Synergistic Research approach to system optimisation. If not, you are still left with a good-sounding conditioner.

Foundation or not? I am using the PowerCell SX in either an entirely non-Synergistic Research treated system or at most one with the Foundation SX cables (tested in Issue 217) and the Black Box bass resonator (tested in Issue 214) in the system. As a result, I will separate the PowerCell SX from its additional field-effect claims, as much as possible. As they are intrinsic to the properties of the PowerCell SX, that's a big ask, but at least I am trying not to place it in an entirely sympathetic system. Nor, for that matter, will I place it in an entirely unsympathetic system (such as mixing Synergistic and Shunyata, as they are like the Sharks and Jets of brands with 'Research' in the name, but with less dancing).

The PowerCell SX on its own does a lot for a system. Sure, it has the 'none more black' dark backgrounds and low noise presentation found in many good conditioners, and it leaves the sound in a good dynamic and rhythmic place, as befits some of the best in 'best for conditioners and filters. The 'first, do no harm' maxim is honoured surprisingly infrequently with power products, as many lean out the dynamic shading as they clean up power chow. The non-current-limiting PowerCell SX is one of the rare exceptions, and for that alone, it gets into the top tier and deserves high praise.

Where the PowerCell SX begins to step beyond 'high praise' is its ability to correctly deal with tonal densities of a note, the raw vibration that ensues, and to separate one from another. This gives the music a sense of harmonic and timbral structure that is often robbed by the juice and not fixed in many conditioners.

I made a rookie error here; I mistakenly thought the PowerCell SX was boosting the size and depth of the soundstage. However, on closer listening, it was more than a combination of better silences between the notes and the PowerCell SX's ability to tease out the structure of the music gave the impression of greater soundstage depth and width. That said, there was a feeling that music was unleashed from the cabinets more when the system was harnessed to the PowerCell SX.

Joie de vivre Most of all, however, the PowerCell SX simply brings out the joie de vivre in a recording. In making the track more engaging, it makes it more impassioned... no matter the music.

Now, back to the Synergistic Research concept album. Not only does the PowerCell SX work in that context, I'd argue it should be the beachhead for the Synergistic invasion. It brings a sense of order to even the least chaotic power, and that makes it hard to put back in its box."

Review

"Will the internal struggle to reach nirvana ever end? Probably not. As much as we like to complain about the journey, this is what provides much of the joy and interest in this hobby. The PowerCell SX has the ability to get us amazingly closer and without major upgrades to the rest of the system—closer than any other cable or power conditioner that I have heard in my listening room. The PowerCell SX clearly pushes the envelope. It's only July, but I now have my first nomination for the annual Positive Feedback Writers' Choice Awards. Highly, highly recommended!"

"With the PowerCell 12, all ships rise with the tide. 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 now laid out for all to hear. In terms of providing clean power, every component in the system has now been maximized for it's best performance and the results have been very clear.

Before spending one dollar on any other upgrade, I highly recommend auditioning the PowerCell 12. This product has made more overall positive impact on my system than any other component over the last several years!"

Soundstage! Ultra "Product of the Year"

The PowerCell 12 UEF SE just might represent the state of the art of power conditioning. It is a testament to the long way Synergistic Research has come since Ted Denney felt that he had yet to discover a power-conditioning technology worth taking further. But in addition to performance, the PowerCell 12 UEF SE offers high value. You won’t find many, if any, competing models that offer 12 outlets, a topnotch power cord, and an AC wall outlet, all for $5995. And while I’m generally not keen on visual gimcracks, that big window in the PowerCell 12 UEF SE’s top plate presents a display that impresses audiophiles and non-audiophiles alike.

Essentially, the PC12 performed sonically beyond my expectations and without any sort of operational glitch... Bottom line, I couldn’t help but marvel at how the PC12 so effectively got out of the way and provided such an impressive platform of high quality conditioned AC to my system. As I said…”Power to (and for) the People!” Highly recommended for sure.

In short, the SR PowerCell 12 UEF SE is a breakthrough in what one can expect from an AC line conditioner. It moved my system in a direction that I have always admired and desired. How it improves specific areas like quiet, dynamics, bass and high frequency extension is very apparent. But overall, I would say that the SR PowerCell 12 UEF SE provides a level of sonic purity superior to any AC conditioner I've heard.

The PowerCell SX power conditioner is the most recent evolution of Synergistic’s PowerCell line. Somehow, its sound significantly betters that of its predecessor, the less expensive PowerCell 12 SE, in terms of such things as noise rejection, transient speed, and transparency. But perhaps its greatest achievement is its similar gains in harmonic richness and tonal accuracy -- music’s calling cards. If there’s a better-performing power conditioner out there, I have yet to hear it.

"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."

"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."

"The resulting impact of these three products is more than the sum of the parts. By that, I mean that with these devices it’s more of a “1+1+1 = 5” effect. The noise floor drops significantly, and with that, I feel like I am hearing everything my system was designed to perform. Honestly, I wish these three devices did not matter as much as they do. It’s a new can of worms to unravel and makes system setup a lot more complex. However, I would never go back to an “untreated” system. The new system sounds more dynamic, more detailed, more lifelike in the soundstage and timbre of the various instruments. In short, it sounds more musical, more real."

I had a hunch that power conditioning would have a major impact on the performance of my system, but this is beyond anything I could have possibly imagined. What I am hearing now belies common sense, What I’m hearing now is almost terrifyingly beautiful.
