The refinement of perfection.
Galileo SX 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 nine parallel geometries utilize our new UEF Graphene Matrix Shielding with a new UEF Graphene Compound first developed for our amazing SR Blue Fuses. For added clarity, each individual geometry is separately sheathed to cancel cable resonance. This gives you 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 double-blind listening test conducted to find alternate conductors for audio cables.
As with Galileo SX Interconnects, we engineered a complex Multi-Layer UEF Inductive Cell and coupled it to each cable’s nine shields, twelve signal conductors and ground and we dramatically improved its function with the addition of a new UEF Graphene Compound first developed for SR Blue Fuses. At the heart of Galileo UEF speaker cables’ 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 and this too was improved over Galileo UEF with the addition of the same UEF Graphene Compound used in SR Blue Fuses.
To custom voice Galileo SX to your system you select between two bespoke UEF Tuning Modules voiced expressly for Galileo SX which have likewise been improved with the same UEF Compound as found in SR Blue Fuses so that the final decision between Silver and Gold is less a trade-off between two unique ’sounds’ and more about choosing between two different options that share far more in common than they did before. The Silver option is uniquely musical with a deeper and richer harmonic structure than the older Silver circuit without giving up detail or nuance in the sound field. The Gold UEF Tuning Module imparts a warm and musical balance replete with maximum soundstage bloom. 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.
Lastly, we treat the entire cable first to the same propriety conditioning process as SR Blue Fuses so that the overall balance is completely musical, relaxed and yet as dynamic and detailed as the most analytical cables on the market, but with the musicality of cables that gloss over dynamics and detail. With Galileo SX you won’t have to compromise between accuracy and musicality, you simply get it all. And we treat them with 1,000,000 volts of electricity on or big Tesla Coil with a new frequency sweep that permanently enhances a cables ability to transmit signal without loss or degradation. You hear all the frequency and phase detail in perfect time alignment and this makes them the most holographic and realistic sounding speaker cables on the planet today.

Gold and Silver Tuning Bullets
Tune your system.
Learn more about Tuning Bullets
We’ve completely reformulated and re-voiced our Galileo Tuning Circuits with new technology designed for the new ultra resolution and musical Galileo SX line of cables. Now Silver Bullets have more detail combined with greater warmth than the prior Galileo Silver Bullets while the Gold Bullets impart even greater musicality and liquid smoothness with a touch more air and detail than before. For best results, it is recommended that you first allow any Galileo SX cable to settle into your system for 72 to 96 hours without removal or handling and without Gold or Silver Bullets attached. Then listen first with Gold, and then with Silver bullets and pick the option that makes music in your system.
Parallel UEF geometries.
The highly complex design of Galileo SX 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 SX 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.
UEF Matrix Shield with Graphene
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 molecule 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.
Matrix Shielding began when we started exploring ways to improve our UEF Shielding by applying UEF Technology first developed for our BLUE Fuses to cables. By placing UEF Tech in a grid pattern on the shields of cables we were able to dramatically lower the noise floor with a surprising increase in musicality or the subjective enjoyment of music. We then began a painstaking double-blind 6-month trial where we would listen to seemingly identical cables marked with random alphanumeric codes to conceal differing patterns of UEF Tech inside each prototype cable and record which options elicited the strongest responses among a control group of listeners. By gauging actual emotional response we were able to isolate grid patterns that better conveyed the essence of music. We would then build on these patterns to find additional patterns that performed better than the last. In this way, our latest shielding technology is highly evolved from anything we have ever done before with each shield pattern selected for its ability to not only lower a cable’s noise floor, but to also convey a greater sense of musical enjoyment.

"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!

"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

"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
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."

"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)"

"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."
