Buy a Black Box Carbon,
Get the HFT Speaker Kit Mk2
OR a Set of Three MiG SRX Footers Free!
(up to $1,195.00 value)
Black Box Carbon
The Black Box Carbon is a mathematically-derived resonator array that eliminate bass nodes and room modes, housed in a carbon fiber and aluminum chassis. Working from the principle that all frequencies in the audible bandwidth are linked through harmonics, when low frequencies are brought into correct phase alignment the benefits cascade upward through every harmonic multiple. Get the phase correct at 20Hz, for example, and it clears up 40Hz, 80Hz, 160Hz, and on. The result is the removal of congestion, allowing music to travel and sound freer, with tighter bass definition, improved detail retrieval, and more accurate image outlines across the frequency spectrum. The Black Box Carbon builds on over a decade of refinement with significant improvements to mechanical resonance control of both the chassis and resonator, delivering greater resolution, more textural bass, and a more natural presentation than ever before. It is also optimized for stacking, pairing beautifully with additional Black Boxes for even more profound impact.
This promotion is designed to take your system further by pairing the Black Box Carbon with one of two complementary paths from the Six Pillars of Synergy.
Choose the HFT Speaker Kit Mk II to extend your acoustic tuning: 14 precisely voiced High Frequency Transducers in asymmetric deployment generate real-time phase-locked energy that corrects room-induced phase and frequency distortion, making your speakers disappear into a holographic soundstage with lifelike spatial realism. Or choose MiG SRX footers to address the mechanical tuning pillar: a Strategic Triad of three unique UEF Metamaterial formulations that govern mechanical energy flow through your components, converting chassis vibration from a source of distortion into expanded dynamics, deeper bass control, and enhanced imaging. Either way, you are building real system synergy.
Global MSRP – $2,395
HFT Speaker Kit Mk II
HFT Speaker Kit MkII dramatically improves your speakers ability to disappear and enable a sonic presentation that is tonally accurate, with the spatial realism and emotional immediacy the music was meant to convey in a way that goes beyond what we believed possible. With six different types of precisely tuned HFT (up from three) featuring faster activation and tighter phase alignment, the breakthrough lies in a new controlled asymmetric deployment where each of the seven positions is independently tuned to complement the others in ways symmetric placement never could achieve. The result transcends what seemed possible: instruments bloom with greater body and truth, vocals hang with stunning presence, and recordings scale effortlessly from intimate ensembles to large orchestras—delivering not just better sound, but sound that feels completely right.
The HFT Speaker Kit MkII isn’t an upgrade—it’s a complete revolution that reconstructs your soundstage’s phase structure from the ground up.
Global MSRP – $895
MiG SRX
Traditional footers attempt to isolate, often at the expense of the music. MiG SRX takes a fundamentally different approach: governing the flow of energy through precision engineering that captures mechanical chaos and converts it into a control vector for holographic realism.
The new precision CNC-machined resonator features strategically varied wall thickness for unprecedented control over energy propagation. And in a world-first for mechanical footers, each set of three contains distinct UEF Metamaterial formulations working together to deliver holographic imaging, bass authority, and high-frequency air without compromise.
Designed for seamless integration with the Synergistic Research field ecosystem, MiG SRX also offers two tuning profiles to dial in the presentation to match your system and preferences.

Ethernet UEF Performance Enhancers
UEF Performance Enhancers are a new UEF filter that lower your system’s noise floor, so you hear more music with greater clarity and less noise for sweeter highs. We start with a new UEF Compound, first developed in conjunction with our flagship cable loom, SRX. When you pop one UEF Performance Enhancer in your system, you’ll find yourself listening longer and, perhaps, at lower volumes as your system seems to flow better. When you insert a second UEF Performance Enhancer, you will likely hear a magnification of what you experienced when only one filter was in your system. Improvements include deeper and tighter bass, an expanded soundstage, and detail that rises above a now lower noise floor. But be careful; UEF Performance Enhancers are powerful, so you may find yourself groovin’ late into the night!

PowerCell 8 SX
Review on Enjoy the Music
So what was the “sudden change” I heard upon first firing up the rig with the new PowerCell? I replayed the same cut I had last listened to and before I could get back to the listening chair I was struck by an increase in pace, rhythm, and timing, greater transparency. By the time I hit the seat, greater macro dynamics had also become obvious. When you know a song well enough, these things quickly come to light. Extended listening over the rest of the song revealed greater resolution, inner detail, and micro-dynamics. While I’m not an electrical engineer, I have to suspect that these initial impressions stemmed from unimpeded current flow, faster rise times, and a lower noise floor which contributed to the instantaneous attack of the notes and greater transparency.
Rick Becker – Enjoy The Music – August 2024
Atmosphere SX Excite AC
The Atmosphere SX Excite Power Cable brings active shielding technology to your AC chain without the complexity of external power supplies. An inboard power supply generates the 30-volt DC bias needed to actively shield its multi-geometry conductors of 6-9’s silver, tungsten, and silver matrix alloy, achieving a noise floor that passive designs simply cannot match. Each cable undergoes our High-Frequency High Voltage Long Duration conditioning process derived from the flagship SRX loom and is internally voiced with Carbon Fibre UEF Tuning Discs for resolution and musicality without high-frequency fatigue.
Plug-and-play simplicity. Flagship-derived performance.

Active Ground Block SX
Sky High Performance
Starts at Ground
The Active Ground Block SX is an active star grounding system that helps eliminate ground noise across up to 32 of your system components, racks and compatible Synergistic Research cable shields and accessories. It combines a massive copper sink to an active filtration system using electromagnetic cells similar to what is found in our PowerCells, all powered by our linear power supply to eliminate EMI and significantly reduce noise coming in from the ground line. We then implement our Ultra-Low Frequency (ULF) Generator to broadcast dual harmonics of the Schuman Resonance. Finally, we house everything in a chassis machined from a solid billet of aluminum and carbon fiber to lower distortion related to mechanical vibration. With the Active Ground Block SX in your system, even with just two or three system components connected, you will hear a reduction of grit resulting in improved articulation, texture, and imaging, across a wider, deeper stage.

PowerCell 8 SX
Review on Stereo Times
Like the predecessor (SR AGB SE) I reviewed back in 2018, the new SR AGB SX reduced the background noise floor and signal compression but to a much higher level. I thought, “This is incredible,” and “It’s like a whole new sound.“ Instruments on the recording, like the piano, bass, drums, and percussion, emerged from a jet-black backdrop with 3-dimensionality, but now with the tone, timbre, and pitch spot on. The location of each instrument was also more defined within the soundstage. Precision is the one word I would use to describe the effect of the SR AGB SX, which was lacking in the previous editions of the SR Grounding Blocks. With the further reduction in noise and signal compression, instruments were separated more while maintaining a natural tonal balance. The benefit of removing internally generated RFI and EMI noise within grounded components was demonstrated. I want to say Hats off to Ted Denney and his gang for doing something special with the SR Active Grounding Block SX.
Mike Girardi, Stereo Times
Atmosphere SX Excite AC
Excite SX has an actively biased shield powered by an inboard power supply with an internal UEF Ground plane for an ultra-low noise floor. Active Shielding means Excite SX has a lower noise floor than would be possible with passive Shielding of this complex multi-geometry power cord. Excite SX expands on Alive SX’s use of pure 6-9 Silver, Tungsten, and Silver Matrix conductors with additional geometries for improved dynamics and resolution. And to raise the bar further, we applied our new High-Frequency High Voltage Long Duration conditioning process first developed for our SRX cable loom and used to make our new Purple Fuses possible. We then internally voiced Excite SX with new Carbon Fibre UEF Tuning Discs engineered to voice the Atmosphere SX loom with increased resolution and musicality without high-frequency fatigue.

Buy a Voodoo streamer / server and get an SRX USB or SRX Ethernet cable free!
(a $5,995 value)
Voodoo Music Streamer / Server
The Voodoo Streamer Server was born from a simple frustration—despite decades of advancing digital cables and components, streaming still sounded compressed and flat compared to our best turntables and tape decks. As Harry Pearson famously said, “If you want to enjoy digital, don’t listen to analog.” We couldn’t accept that limitation.
After perfecting our Ethernet Switches and Network Routers, we turned to the final link: the server itself. We leveraged fifteen years of EM Cell technology from our PowerCell line conditioners, advanced LPS power supplies, and ULF bias technology from our Galileo Ground Blocks to create the world’s most musically robust server architecture. Through extensive double-blind testing, we selected only the most resolved and musical motherboards, processors, and RAM configurations.
The breakthrough came when we adapted our ULF bias technology to eliminate the high-frequency noise inherent in digital circuits. This finally overcame digital compression and annoying artifacts we assumed were intrinsic to the format. Now digital sounds spacious and transparent while analog sounds compressed by comparison—a complete reversal of what we’ve accepted for decades.
Built in a CNC-machined aircraft aluminum and carbon fiber chassis that acts as a massive heat sink for silent, fan-free operation, the Voodoo runs Roon software for the ultimate user experience. For maximum performance, use dual units—one as core, one as bridge—allowing each to focus on its specific function.
Transform your digital experience with the server that finally makes streaming rival your best analog sources.

SRX USB
SRX USB shares the same hallmarks as the rest of the SRX lineup. Namely, an ultra-low noise floor with inner detail, dynamics, and holographic realism to rival the best analog playback while setting a new digital benchmark. Anyone experienced with master tapes understands there is a significent difference between the best of digital and tape, with tape possessing detail, musicality, dynamics and three diminsionalility not found in other formats. SRX Digital takes your state-of-the-art DAC close to your best tapes in your reel-to-reel deck while surpassing the majority of tapes in your library. And if you are a vinyl lover, you will find many of your files, CDs, and SACDs can now compete with and surpass all but your best vinyl recordings. To set this new digital standard, we start with an exploded geometry comprising two 3rd Gen Silver Matrix geometries, and four Silver Air Strings.. Each Air String is hand-made in our California factory from 99.9999% pure silver in an air dielectric with a UEF grid running the cable’s length to lower the noise floor and expand the sound field. We then apply the SRX Long Duration Multi-Frequency High Voltage Conditioning Process for enhanced clarity, musicality, and detail without fatigue. And for a lower noise floor still, connect the SRX Digital’s Ground Plane to an Active SR Ground Block. Each hand-made geometry and ground plane is run through carbon fiber discs to maintain separation between conductors for lower capacitance and cross-talk. Voicing the cables to your system is easy with supplied Gold and Silver SRX Carbon Fibre UEF filters. Gold will deliver a warmer and more liquid sound, while silver has increased air and focus. You decide between Gold and Silver Tuning Circuits by listening to your two options for a bespoke system match.

Galileo SX Ground Block Mk II
Audio components create electromagnetic interference and noise that pollutes your system’s ground plane, while poorly designed ground paths can add up to 10dB of signal-damaging noise through normal current-carrying circuits. We’ve re-engineered our award-winning Galileo SX Active Ground Block using breakthrough technology from our flagship Galileo SX PowerCell to provide a separate, superior conductive path to earth ground that eliminates this contamination. The machined aluminum and carbon fiber chassis with three Active EM Cells and copper mesh Ground Plane dramatically reduces noise while creating a jet-black sonic background with previously unnoticed detail that even sophisticated electronics cannot achieve on their own.
Major upgrades include a dual-channel ULF generator with 2x signal strength that synchronizes your system to Earth’s natural 7.83Hz Schumann Resonance—the planet’s electromagnetic “heartbeat” generated by lightning strikes—which acts as dither to overpower room interference for more effortless, musical flow. This delivers increased deep bass power and weight, more holographic soundstaging, smoother high frequencies with greater extension, and a more present, layered mid-range with increased tonal density and resolution—improvements so dramatic they’re like upgrading from standard resolution to Double DSD.
With 70 ground ports, advanced linear power supply with new LPS technology, and simple button tuning to optimize ULF frequency for different system configurations, you can connect turntables, DACs, preamps, power amps, and any component with active circuitry to this revolutionary ground filtering technology that transforms modest components to perform far above their class.

Galileo Discovery
AC Power Cable
Our Galileo Discovery power cables represent 25 years of power cord development perfected, combining ten parallel geometries with our highest-performance Active EM Cell from the SR25 and SRX programs. This creates both a high-resolution power cable and active AC filter that eliminates cross-contamination between analog and digital components while delivering exceptional resolution without sacrificing musicality—something that’s typically challenging to achieve.
The cable features a Swiss-made power supply powering the Active DC Biased Shield and carbon fiber-encased Active Noise Canceling EM Cell, utilizing UEF Technology from our Purple Fuses development. Our breakthrough Purple Fuse UEF Compound adds harmonic richness while opening the soundstage with extended highs and bass, plus new UEF Matrix Shielding that interacts with surrounding EM fields for the lowest possible noise floor. For enhanced performance, the shield can be optionally grounded to any Synergistic Research Active Ground Block.
Each cable includes Gold and Silver SRX Carbon Tuning Circuits for system optimization—Silver delivers detailed dynamics with pinpoint imaging, while Gold provides liquid smoothness with excellent detail. After a 72-hour settling period, you can compare tuning circuits cable-by-cable to create a bespoke power loom perfectly matched to your system and preferences, realizing the best of both worlds for truly customized performance.

SRX Power Cable
The technology for our new SRX power cord comes direct from our SR25 25th Anniversary power cord that was limited to 100 pieces worldwide. The SRX is an exact duplicate of the now sold-out SR25 with one exception, we are using a different grade of pure six-nines silver, and this cuts the cost of our reference power cord in half. Each SRX power cord is fabricated by hand in our California factory including a flexible pure silver signal path ribbon laminate that acts as an Electromagnetic Cell running the full length of the cable from the wall plug to the IEC. Additional AC conductors are made from pure six-nines silver in an Air Dielectric for a total of nine gauge of pure silver each for the hot and neutral run. In every respect, the SRX represents the zenith of what we currently know on building the world’s state-of-the-art power cord. SR technologies include the most advanced UEF shielding we have ever developed for a power cord and the most complex duel folded electromagnetic cells we have placed in a power cord made from pure six nines silver for both the hot and neutral AC leg. With a long flexible flat EM Cell and two folded EM Cells all made from pure six-nines silver, you have in effect a pure silver PowerCell line conditioner in an AC cable format.

HD SX Ground Cables
Since engineering our original HD Ground Cables in 2015, our understanding of building the world’s best-sounding cables has advanced exponentially. In areas such as metallurgy, UEF compounds, and high voltage and high current conditioning processes have collectively gone well beyond anything we could have imagined ten years ago. So it was time we applied all we’ve learned to build the next generation HD Ground Cable. We started with the same hand-made AirString Geometry. We added a new single crystal pure six-nines silver conductor in an air dielectric for cleaner highs and a noticeable increase in resolution combined with a more relaxed presentation. We then add a new UEF Compound to a new Matrix Shield for an even lower noise floor in a more holographic soundscape. We then added our brand new Three Stage High Voltage conditioning process initially developed for our new flagship SRX cables for a dramatic lowering of the noise floor. All told, these improvements create a whole new level of performance, resolution, and musicality. In short, adding our new HDSX Ground Cables to your system with any of our Ground Block technologies will improve all aspects of sound, and not in a subtle way.

Ethernet UEF Performance Enhancers
UEF Performance Enhancers are a new UEF filter that lower your system’s noise floor, so you hear more music with greater clarity and less noise for sweeter highs. We start with a new UEF Compound, first developed in conjunction with our flagship cable loom, SRX. When you pop one UEF Performance Enhancer in your system, you’ll find yourself listening longer and, perhaps, at lower volumes as your system seems to flow better. When you insert a second UEF Performance Enhancer, you will likely hear a magnification of what you experienced when only one filter was in your system. Improvements include deeper and tighter bass, an expanded soundstage, and detail that rises above a now lower noise floor. But be careful; UEF Performance Enhancers are powerful, so you may find yourself groovin’ late into the night!

SRX XL Power Cable
The Synergistic Research SRX XL AC is the ultimate power cable for delivering an audible transformation to your entire audio system. Optimized for all components—from sensitive preamps and DACs to demanding power amplifiers and line conditioners, the SRX XL elevates performance beyond what you thought possible from a power cable.
Expanding on our acclaimed SRX design, we added two additional pure silver 14-gauge high-current geometries and two pure silver AirString geometries. This creates an air-dielectric pure silver conductor system that establishes a new benchmark for audio power delivery. We also developed an entirely new UEF compound to elevate the performance of our previous Matrix Shielding, which further lowers each cable’s noise floor while lessening restraints a shield may have on signal transmission. Last, we run each cable through our most advanced SRX XL High Voltage Conditioning, treating cables with 1,000,000 volts of electricity at specific frequencies and pulse modulations for long durations, creating a canal in the conductor material and contact points at the molecular level that allows electrons to flow more freely. These advancements don’t compromise SRX XL‘s flexibility, so it’s easy to connect, even in tight spaces, like behind your rack or furniture.
SRX XL delivers enhanced soundstaging, dramatically lower noise floor, and increased high-frequency extension with exceptional smoothness for a high-current power cord like no other, sounding even more open and accurate than any cable before them. But don’t take our word for it – hear the difference in your own system with our no-risk trial program. And if you already have a complete loom of SRX power cords in your system, ask your dealer or distributor how you can take advantage of our Lifetime Passport Protection Plan, where you receive a 70% trade-in allowance for your existing SRX power cords toward a new loom of SRX XL power cords.

Tranquility Carbon
Condition Signal From Within
The Tranquility Base Carbon is field generator and ground plane that conditions electromagnetic fields within adjacent electronics to lower your system’s noise floor. Being the first all-new Tranquility Base redesign in over a decade, we started with a new chassis machined from a solid billet of aircraft aluminum for a 50% slimmer and 80% more rigid chassis. We then experimented with new laminates and arrived at carbon fiber for its superior response to mechanical and airborne vibrations. We then applied our most advanced EM Cell technology directly transferred from our Galileo SX PowerCell. Finally, its internal UEF Technology was transferred from our new state-of-the-art SRX cable loom. The net result is a thinner and more rigid Tranquility Base with a lower noise floor from which springs improved dynamics and soundstaging combined with smoother, more extended high frequencies.

Tranquility Base Carbon XL
Tranqulity Linear Power Supply
Our Tranquility LPS features technology and innovation found in some of our most renowned products, borrowing learnings from the power supply of our Galileo SX PowerCell and employing both electromagnetic conditioning and high voltage conditioning processes common in many of our products. And to take performance further, we engineered a chassis machined from a solid billet of aircraft aluminum to act as a massive heatsink with a carbon fiber top to break up the mechanical resonance created by your stereo speakers. By powering up to 12 components, you significantly increase the impact of Tranquility Bases, Tranquility Pods and FEQ Carbons by allowing them to operate through a lower noise floor and commonly shared UEF principles.

PowerCell 8 SX
Review on Stereo Times
Like the predecessor (SR AGB SE) I reviewed back in 2018, the new SR AGB SX reduced the background noise floor and signal compression but to a much higher level. I thought, “This is incredible,” and “It’s like a whole new sound.“ Instruments on the recording, like the piano, bass, drums, and percussion, emerged from a jet-black backdrop with 3-dimensionality, but now with the tone, timbre, and pitch spot on. The location of each instrument was also more defined within the soundstage. Precision is the one word I would use to describe the effect of the SR AGB SX, which was lacking in the previous editions of the SR Grounding Blocks. With the further reduction in noise and signal compression, instruments were separated more while maintaining a natural tonal balance. The benefit of removing internally generated RFI and EMI noise within grounded components was demonstrated. I want to say Hats off to Ted Denney and his gang for doing something special with the SR Active Grounding Block SX.

Atmosphere SX Excite AC
Excite SX has an actively biased shield powered by an inboard power supply with an internal UEF Ground plane for an ultra-low noise floor. Active Shielding means Excite SX has a lower noise floor than would be possible with passive Shielding of this complex multi-geometry power cord. Excite SX expands on Alive SX’s use of pure 6-9 Silver, Tungsten, and Silver Matrix conductors with additional geometries for improved dynamics and resolution. And to raise the bar further, we applied our new High-Frequency High Voltage Long Duration conditioning process first developed for our SRX cable loom and used to make our new Purple Fuses possible. We then internally voiced Excite SX with new Carbon Fibre UEF Tuning Discs engineered to voice the Atmosphere SX loom with increased resolution and musicality without high-frequency fatigue.

Review on Enjoy the Music
So what was the “sudden change” I heard upon first firing up the rig with the new PowerCell? I replayed the same cut I had last listened to and before I could get back to the listening chair I was struck by an increase in pace, rhythm, and timing, greater transparency. By the time I hit the seat, greater macro dynamics had also become obvious. When you know a song well enough, these things quickly come to light. Extended listening over the rest of the song revealed greater resolution, inner detail, and micro-dynamics. While I’m not an electrical engineer, I have to suspect that these initial impressions stemmed from unimpeded current flow, faster rise times, and a lower noise floor which contributed to the instantaneous attack of the notes and greater transparency.

Atmosphere SX Euphoria AC
Atmosphere Euphoria SX Power Cables are an all-out assault on your system’s noise floor. In this pursuit, we employ Active Shielding, the option to ground its shield to a star ground point or SR Ground Block, and Galileo SX tuning bullets for a bespoke sonic match to your system. All conductors, wall and IEC connectors, shields, and the same Swiss-Made power supply found in our Galileo SX power cords are further treated with a proprietary process to improve frequency smoothness with increased resolution. Sonically Euphoria SX is voiced to express a sonic balance similar to our Galileo SX power cords through the use of Copper Matrix Alloys, 6-9 Silver conductors in a complex geometry array comprised of three hand-made Air String geometries and three High Current geometries running in parallel. In addition, Active Shielding gets its power from a Swiss Made power supply feeding the shields and an Active EM Cell that was first developed for Galileo SX power cords to function as discrete PowerCell line conditioners. We then voiced the power cords internally with new Carbon Fibre UEF Tuning Discs exclusively engineered for Atmosphere SX cables to push resolution boundaries without harshness or limitations. Lastly, you can voice Euphoria SX with included Galileo SX Gold and Silver UEF Tuning bullets.
