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.
