Synergistic Research Active Ground Block SX January 2026 Bundle - BIG Power Cable Upgrade!

Synergistic Research Active Ground Block SX January 2026 Bundle - BIG Power Cable Upgrade!

January 2026 Active Ground Block SX Bundle

NOTE: throughout January 2026 if you purchase an Active Ground Block SX you get upgraded FREE  to the Atmosphere SX Excite AC power cable (normal RRP for the Atmosphere Excite SX is £2,495)!

The price of £2495 is for non UK version power cables and this listing is for the upgraded UK plug version so £150 is added to total bundle price.

Active Ground Block SX 

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 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 Synergistic Research`s PowerCells, all powered by their linear power supply to eliminate EMI and significantly reduce noise coming in from the ground line.  

Synergistic Research then implement thier Ultra-Low Frequency (ULF) Generator to broadcast dual harmonics of the Schuman Resonance. Finally this is housed in a chassis machined from a solid billet of aluminium and carbon fibre 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 noise resulting in improved articulation, texture, and imaging, across a wider, deeper stage.

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 Analogue Converters (DACs) – Connect to spare Digital Input, Output or Chassis Ground

⦁ Reel to Reel Tape - Connect to spare Analog Input, Output or Chassis Ground

⦁ Pre-Amplifiers – Connect to spare Analog Input, Output or Chassis Ground

⦁ Power Amplifiers – Connect to spare Analog Input, Output or Chassis Ground.  Note:  Many power amplifiers will sound best without the ground engaged.  Try your power amp and speaker cables with and without the ground attached and choose what sounds best for your system.

⦁ USB Devices – Connect to spare USB Input, Output or Chassis Ground

⦁ Audio Computers - 3.5mm Headphone Jack

⦁ Any Component with an active circuit inside – Connect to spare Input, Output or Chassis Ground

BIG UPRGRADE: The normal AC power cable supplied with the Active Ground Box SX is the Foundation SX 5ft (1.50 metre) which has an RRP of £599.00 BUT this is upgraded to the Atmosphere SX Excite AC Power Cable FREE!

Atmosphere SX Excite AC Power Cable 

Atmosphere 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 Atmosphere Excite SX has a lower noise floor than would be possible with passive Shielding of this complex multi-geometry power cable. 

Atmosphere Excite SX expands on the entry level Atmosphere 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, Synergistic Research applied thier new High-Frequency High Voltage Long Duration conditioning process first developed for  SRX cable loom and used to make the Purple/Pink fuses possible. 

The Atmosphere Excite SX is internally with the new Carbon Fibre UEF Tuning Discs engineered to voice the Atmosphere SX loom with increased resolution and musicality without high-frequency fatigue.
