Heighten your senses.
Galileo UEF Speaker Cables are made by hand in our California factory from (4) High Current Silver Matrix geometries, (1) 4th Generation Tricon Silver Matrix geometry, (3) Hand Made Pure Silver / Graphene AirString Geometries and (1) Hand Made Pure Tungsten AirString geometry. All 9 parallel geometries utilize our patent pending UEF Graphene Shielding for a total of 18 cables in a single pair of Galileo UEF speaker cables. For added clarity each individual geometry is separately sheathed to cancel cable resonance for clear effortless sound with natural decay and timbre. When voicing these speaker cables we added a Tungsten AirString Geometry for the unique sound staging properties of tungsten as determined during a 6 month long double blind listening test conducted to find alternate conductors for audio cables.
As with Galileo UEF Interconnects, we engineered a complex Multi-Layer UEF Inductive Cell and coupled it to each cable’s 9 shields, 12 signal conductors and ground. The heart of Galileo UEF speaker cables’s performance is its UEF Inductive Cell made from Pure Silver Foils and Graphene with a dielectric made from Japanese Silk chosen for the warmth and layering silk delivered over traditional dielectric materials discovered during a series of double blind listening tests. For versatility and system compatibility Galileo UEF speaker cables can be run shielded with the ground plane connection attached to either a SR Ground Block, or with the included ground connector. Additionally they can be used without shielding for mono block amplifiers and speakers that perform their best when run with unshielded speaker cables. Simply connect the shield to ground or leave it disconnected. One advantage of our exclusive UEF Graphene Shielding is that it works whether the shield is connected to ground, or not.
To custom voice these speaker cables to your system you select between two bespoke UEF Tuning Modules voiced expressly for Galileo UEF. The Gold UEF Tuning Module imparts a warm and musical balance replete with maximum soundstage bloom or select the Silver UEF Tuning Module when your system sounds best with a more detailed and pin-point sound stage balance. A third option is to simply not attach either UEF Tuning Modules but the choice is yours to make based on the option that makes music in your system.

Galileo UEF Ground Plane
Performance starts at ground.
The optional Ground Plane connections on your new Galileo UEF Speaker Cables allow you to star ground all of your Galileo UEF cable shields to reduce your systems signal-to-noise ratio. The Ground Plane provides the ultimate mechanism for removing the buildup of harmful excess charge and static attempting to decrease the performance of your system. With blacker backgrounds and greater low-level information retrieval, you experience music in a whole new way. For the ultimate system grounding, add a single Ground Block to improve the your system’s ground performance, interconnects, speaker cables and component grounds or use the included ground connection for each pair of Galileo UEF cables in your system.
Note: Many amplifiers will sound best without the ground shield engaged. Try your cables with and without the ground pigtail attached to a ground block and choose what sounds best for your system.
Gold and Silver Tuning Bullets

Fine tune your musical investment to perfectly match your taste and exceed your expectations. UEF Tuning Modules are connected to Galileo UEF cable shields and work outside the signal path to 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. Silver UEF Tuning Modules are fast resonators that maximize clarity and detail while Gold UEF Tuning Modules are a slower resonator for a sound that is warmer with more bloom and in some instances, more musical. When combining both Silver and Gold UEF Tuning Modules by selecting Silver for say Interconnects, and Gold on speaker cables, you can enjoy the best of both or experiment with different combinations until you find just the right balance for your state-of-the-art system.
Parallel UEF geometries.
The highly complex design of Galileo UEF Speaker Cables includes 20 individual and isolated UEF geometries. These multiple signal runs consist of our award winning “Pure Tungsten” and “Silver Matrix Alloy” conductors coupled with Pure Silver Monocrystal Filaments housed in “air dielectric” PTFE tubes. Combinations of these conductors are then separately shielded with UEF Ground Planes, providing the purest form of audio signal transfer. With Galileo UEF Speaker Cables in your audio system, you will hear and experience 3-dimensional holography that extends far beyond your speaker boundaries, and a stunning depth of realism that is rarely achieved with recorded music.
Synergistic Research is the World’s first cable company to incorporate Graphene, a new, highly conductive wonder material that consists of a layer of pure carbon 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). With Graphene you get superconductor performance without the deep freeze.

How to use tuning modules.
"Along with the SRX power cords, Andy also sent me a Galileo SX Ethernet cable to try between my router and the Aurender N10. I was using an off the shelf inexpensive Cat 5 Ethernet cable that came with some home router hardware (I know, sacrilegious at the very least). I also experimented with the Audioquest Vodka ($339/1.0M) and Nordost Heimdall II ($699/1.0M). Both were clear upgrades from the standard Cat 5, but neither persuaded me to use either Tidal or Qobuz for serious listening.
The Galielo SX Ethernet Cable ($2995 /1.0M) was a different story. Yes, based on MSRP alone, this is not a fair apples to apples comparison, but the differences were substantial. For a more detailed description of the sound, you can check out my earlier Galileo SX review that included interconnects, speaker cable, and power cords (HERE). The difference that the Galileo SX Ethernet cable can make was relatively the same as the other cables described in the review. I am sure that most are not surprised, but the bottom line here is that cable quality can make a difference—even for streaming, and even for Ethernet cable! I am now digging deep on Tidal and Qobuz, and just for the record, I am greatly satisfied by both!

How much do I love these cables? I love them so much that I brought a Gallileo SX USB cable with my portable play back system on a recent trip. I love them so much that I will never again listen to digital audio without them. It's impossible for me to un-hear the difference these cables have made for my listening experience which is why they are now mainstays in my studio.

The design advantages provided by the implementation of an internal Active EM Cell, the ability to directly ground the Active EM Cell, and a new developed UEF Matrix Shielding were clearly demonstrated during the review. The approach taken by SR to conduct double-blind trials and selecting the preferred UEF technology based on the emotional connection to the music as one listens proved to be highly successful and validated repeatedly in my listening room. In similar fashion to how the SR Active Grounding Block SE performed in my system, the resulting lower noise floor and frequency uniformity delivered by the Galileo SX AC power cables have allowed me to listen to music at lower volumes without loss of detail, silence between notes, and dynamics. With the Galileo SX cables, it’s much easier to become emotionally connected to the music on many levels.

"This was my first exposure to the new Synergistic Research Galileo SX phono cable. This $5,000 phono cable has transformed my analog playback, something I would have sworn was already exceptional. Am I finally hearing all that my VPI Scoutmaster is capable of? It feels like it, which is why I think the SX is the finest phono cable I have ever heard. I’m unapologetically a fan of Synergistic Research designs, but this may be the best thing they have ever done. It’s that good.
Now, I am addicted to this newish analog rig. I go down to my first-floor listening room every Saturday and Sunday and listen to jazz, rock, and classical music. What I am now hearing, every time I pull out an old favorite, is more musical information. I am hearing new things going on in the background. It’s mesmerizing.
It’s not a bold claim to say that this cable handily meets my four conditions, so let me go farther: the Synergistic Research Galileo SX is the clearest, most musical phono cable I have ever used in my reference system. Beyond expectation, this cable has transformed my analog playback. It is my new reference for what my record player is capable of, and as such, it earns my highest recommendation."
Lee Scoggins, Part-time Audiophile, September 2019
"My goodness! I thought that I knew this LP inside out, but there is something scary going on here. I feel like I just walked into the actual recording venue. There is a feeling of space and resolution that I never realized was on this recording. By the way, please tell Ben Webster to stop spinning around and to stand still!" And then that gorgeous smile.
It's an interesting thing (at least for me), that when evaluating new components and seeking specific improvements in your system, many times you know pretty much what you are looking for. Better bass. More detail. Improved harmonics. And so on. When you discover improvements for something that was not all that apparent before, it can be quite a revelation and an eye opener—especially if it can provide a dramatic new emotional connection with the music.

"According to Ted, yours truly played a part in the voicing of the Galileo UEFs, at least to this extent: After all these years Denney has a pretty good idea of the timbral and dynamic balance I prefer and he made an effort (or so he tells me) to engineer higher energy, higher resolution, and more neutral timbre into the UEFs. As you can already gather from what I’ve written he has succeeded beyond expectation. This is simply the most neutral (least darkly colored), most faithful to sources, highest resolution, most dynamic, and, given the right source material, most realistic-sounding wire he’s built. Voices and instruments aren’t just unmistakably “right” in timbre, pitch, duration, and dynamic; they also have the lifelike bloom that you hear listening to real instruments being played in a club or a concert hall—the “action” that turns (in HP’s famous paraphrase) painted ships upon a painted ocean into three-dimensional semblances of real-life instruments making real-life music.
Jonathan Valin - The Absolute Sound - Issue287 - Sept. 2018
"The Galileo SXes are indeed audio’s Ferrari Monzas. No other cable I know of is fully competitive with them on any of their strengths: imaging, transparency, speed, leading edges, detail, noise reduction, dynamics. But don’t let my infatuation with their technical prowess diminish what seems to be these cables’ raison d’être: the reproduction of music. They offered musicality in spades, and on several occasions got me up off my couch and dancing. In “Love Reign O’er Me,” they conveyed Bettye LaVette’s emotional intensity to the point that I wanted to cry. Listening to Pink Floyd’s “Shine On You Crazy Diamond” with the lights low, I felt as if I were on a futuristic set from Blade Runner. These cables should appeal equally to your heart and mind."

"2016 Cable of the Year"
"Ted Denney’s latest creations improve on the cumbersome ergonomics of his original Galileo multi-strand cables (which had to be plugged into and out of a multitude of boxes and actively biased via a plethora of wall-wart power supplies) by packaging most of that marvelous Synergistic technology into the cable itself. Better still, the Galileo UEFs significantly improve upon the truly stellar sonics of the original Galileos. Indeed, the UEFs are the best sounding wires Mr, Denney has yet devised, achieving a dead-center neutrality that is neither “bottom-up” nor “top-down” in tonal balance, without any sacrifice in natural warmth and timbre, resolution of detail, transient speed, dynamic power, imaging precision, or soundstage width, depth, and height. When you consider that the Galileo UEFs are also priced at one-third or one-quarter of what the original Galileos went for (and roughly one-tenth of what flagship cables and interconnects from certain other companies currently cost), you have a veritable bargain in ultra-high-end wire and a worthy TAS Interconnect and Speaker Cable of the Year Award winner."
"2018 Brutus Award"
Without question, the Synergistic Research Galileo SX are the finest cables that I have used in my system. Through this new innovative design, Synergistic Research continues their all out assault on the noise floor which allows for a blacker and deeper background. Music just seems to naturally flow and radiate from the soundstage. Two words kept coming up in my notes as I listened to these cables extensively. Those two words were "ringing" and "smear" or the amazing lack of both. This is all executed without the traditional Synergistic Research implementation of active shielding which has been succeeded by a combination of Matrix UEF shielding, ground plane connectivity, and extensive use of graphene materials. A must audition for those seeking the very best.
"2017 Cable of the Year"
"JV has heard a lot of Synergistic Research cable over the years, but Ted Denney's latest creation, the Galileo UEF, is quite simply the best wire Mr.D has yet designed- better even than the original Galileo, which cost four times as much. Although it is still a bit of a pain to use - because of the various grounding connections required - Galileo UEF is far less of a pain than previous SR wires, simply because the dielectric biasing circuit is built into each cable. (No more wall-wart power supplies stuck in every outlet and power strip of your home.) More importantly, the UEF marks a dramatic shift in SR sonics, coming far far closer to neutral in balance than the darker-sounding originals, without sacrificing any of the speed, color, resolution, or power-range solidity and slam that SR is famous for. A genuine breakthrough for Denney and Co., a relatively good deal compared to some of the six- and seven-figure competition, and a shoo-in for TAS' 2017 Cable and Interconnect of the Year Aware. (forthcoming)"
Setting up Jonathan Valin of TAS with Synergistic's best
"Like the SR Galileo UEF speaker and interconnects, the SR Galileo UEF power cords make components sound exceptionally neutral, rich in texture, full of body, powerful, fast, spacious, and detailed while allowing my system components to reach their full potential. The Galileo UEF digital and analog power cables on all system components checked all of the boxes for me."

"Best Sound at Show" T.H.E. Show Newport
"Although the Atmosphere UEF Level 4 cables are excellent cables within their price point, the technology employed in the Galileo UEF cables significantly improved upon the performance of the Atmosphere UEF Level 4 cables. Inner detail, low level musical signal retention, and the ability for the listener to easily pinpoint outlines within a well-defined soundstage were exemplary through the Galileo UEF cables. Instruments and vocals sounded lifelike and not electrically constructed through the Galileo UEF cables. The lower noise floor conferred many benefits in the areas of micro and macrodynamics which for me, is at the heart of enjoying recorded music… I have a new reference."
Michael Girardi, Stereo Times, Issue 91, June 2017
"If all this makes it sound as if the Galileo UEFs do virtually everything at the breathtaking levels of a Zenvo TS1, Bugatti Chiron, or Hennessey Venom GT Spyder, it’s because they do." "Synergistic Research’s Galileo UEF interconnects and speaker cables are technical tours de force that demonstrate just how far the art of cable making has come since the Golden Enz days of electrical-grade copper conductors and connectors of gold-plated nickel. They serve as a reminder of three audiophile truths: the simplest circuit does not always sound the best, the highest-performing products are often not the most expensive, and despite all the amazing progress made, the art continues to advance."
Howard Kneller, SoundStage Ultra, September 2017
"I could tell something was different from the first note. There was a sense of unfiltered and unprocessed natural clarity to the sound. The noise floor was so non-existent and deeply black that the level of detail and individual notes just seemed to pour out from the Sonus Faber Stradivari speakers, but with a liquidity and ease that was new to my ears."

SR Ground Block (optional):
Galileo UEF interconnects have shields that can be grounded direct to earth with supplied ground cables bypassing your component’s power supplies for a lower system noise floor.
- To improve performance further still use an optional SR Ground Block with its UEF Ground Filter to elevate overall system performance; not only can you star ground and UEF filter the shields on all Galileo UEF interconnects and speaker cables in your system, but can also ground all of your system’s components to the Ground Block for a dramatic lowering of your system’s noise floor for greater detail, clarity and musicality.
- Many amplifiers will sound best without the ground shield engaged. Try your cables with and without the ground pigtail attached to a ground block and choose what sounds best for your system.
