About Synergistic Research Active Ground Block SX
Synergistic Research Active Ground Block SX Key Features:
- Machined aluminum chassis with carbon fiber reinforcement – minimizes vibration-related distortion for greater sonic clarity.
- Newly designed power supply – delivers the lowest noise floor of any Active Ground Block for blacker backgrounds and enhanced detail.
- Dual harmonics of the Schumann Resonance – expands dimensionality and realism, creating a more immersive soundstage.
- 32 ground connections – supports more components, cables, and system elements for comprehensive system grounding.
- Wide application compatibility – integrates seamlessly with turntables, DACs, preamps, amplifiers, and digital sources to elevate overall system performance.
Product Description:
Sky High Performance Starts at Ground
The new Active Ground Block SX is an evolution of the Galileo Active Ground Block, incorporating both its proven design elements and newly developed technologies. Its chassis, machined from a solid billet of aluminum and reinforced with carbon fiber, reduces vibration-related distortion for greater clarity. A new power supply, informed by lessons from the Linear Power Supply program, delivers the lowest noise floor of any Active Ground Block to date. Performance is further advanced through dual harmonics of the Schumann Resonance, a breakthrough first created for the upcoming Galileo PowerCell. The SX also improves practicality by increasing the number of ground connections from 22 to 32, allowing additional components, cable shields, racks, or other conductive system elements to be grounded. With these advancements, the Active Ground Block SX proves that ultimate performance begins at ground level.

Applications
- Synergistic Research Galileo UEF and Atmosphere Cables
- Synergistic Research Tranquility Bases
- Synergistic Research Atmospheres
- Turntables – Standard or Small Spade Connect to Ground Post on Turntable
- Phono-stage - Standard or Small Spade Connect to Ground Post
- Digital to Analog Converters (DACs) – Connect to spare Digital Input, Output or Chassis Ground
- Reel to Reel Tape - Connect to spare Analog Input, Output or Chassis Ground
