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.
Audition the Active Ground Block SX in your system and discover why we say ultimate performance starts at ground level!

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.
