Synergistic Research Active Ground Block
SUMMER SALE! Until July 31st trade in your existing Grounding Block for 100% of the global retail price ($595) regardless of the price you paid.
The New Active Ground Block takes the award winning UEF Ground Filter from our original SR Ground Block and adds an active ULF Field Generator, and on the SE model, a dedicated Active EM Cell as found in SR PowerCell line conditioners to supercharge the performance of every component in your system including Synergistic Research cables equipped with external grounding technology.
Benefits include a noticeable increase in deep bass power and weight, a more holographic sound field, smoother high frequencies with greater extension and ‘air’, a more present and layered mid-range, increased tonal density with an apparent increase in resolution; it's like going from a standard resolution Redbook file to Double DSD, the improvement is that dramatic.
Nearly every aspect of system performance is transformed over the original; in fact, the difference between the new Active Ground Block and our original SR Ground Block is greater than the difference between the original Ground Block and no ground filter at all!

It all starts with 44 Star Ground Points to reduce component to component ground inductance. That’s 44 ground connections to the original’s 18. You can ground your entire system including all components, a full loom of SR cable shields, and even equipment racks, computer hard drives, absolutely everything in your system can be grounded to one SR Active Ground Block.
Filtration is handled by a UEF Ground Filter that’s 3 times the size of the original's UEF Ground Filter and this translates into 3 times the performance of the passive ground filter alone.
To this we add an Active ULF Field generator as found in our PowerCell 12 UEF which re-clocks high-frequency ground noise to the Earth’s Schumann resonance as well as noise generated inside connected components at the circuit level, so each connected component’s performance is fundamentally transformed at the source. And the Active Ground Filter is the only ground filter in the world to use such a filter mechanism for a performance unlike anything you’ve ever experienced.
Stepping up to the Active Ground Block SE replaces the standard model’s passive Quantum Black Power Cord with a specially modified Atmosphere Level 2 Active power cord equipped with Galileo UEF Quantum Gold and Silver Filters that give you two distinctive sonic options to the overall sound of your system.
With the included Galileo UEF filters you perfectly tailor the sound of the Active Ground Block SE to match your system, or leave the Galileo UEF Filters disconnected, the choice is yours.
Lastly, the SE version has an Active EM Cell similar to the EM Cells found in our PowerCell 8 power conditioners to actively remove noise from ground for even blacker backgrounds, with improved dynamics, and finesse.
Reviews and Awards for the original non-active Grounding Block.
Howard Kneller, UltraAudio.com, March 2017:
"...when I connected Synergistic’s Grounding Block to my Esoteric K-01X SACD/CD player, the results were astonishing. Noise and digital grunge were reduced, imaging and microdynamics improved, and soundstage size and perceived gain increased… the result of decreased dynamic compression and a much lower noise floor. That plugging a $595 device into a $20,000 component could have that kind of effect was mind-blowing..."
"...the cumulative effect of completely grounding my system was unforeseen. Details, imaging, soundstage size, dynamics, noise reduction, perceived gain, and transient impact all dramatically improved..."
"...I conclude that Synergistic’s Grounding Block is no mere accessory or tweak, but a necessity. After letting it work its magic, I realized that the power supplies of audio components, even really expensive ones, aren’t designed to remove much of the signal-damaging electromagnetic demons that ride our electrical lines..."

Mike Girardi, The StereoTimes, Dec.2015:
"...I wouldn’t hesitate to recommend the High Definition Grounding cables. The expense is justified by that delivered performance. The addition of the SR GB and HDG cables exceed my expectations and was similar to the level of improvement the SR Powercell 10 SE MKII I reviewed back in 2013 brought to my system. The more I listened to my system with the HDG cables and Grounding Block, the more I was convinced that the addition of these products are on the critical path in assembling a truly high performance audio system..."

Dr. David W. Robinson, Editor-in-Chief, PFO, November 2015:
"...this component provides a common grounding point for a system, via grounding cables that connect to the central block via pins. The effect on our system was immediately obvious: A thin layer of hash that had been below my notice (Ain't it always the way?) was removed, clarifying a system that I already thought was exceptional. And this is the constant challenge of fine audio...you learn about the presence of "layers" in playback by subtraction. As Joni Mitchell sang in her song, "Big Yellow Taxi," "You don't know what you got ‘til it's gone." Well, yeah. And that's how it is with noise floors and transparency in audio. Certainly the Grounding Block knocked down some haze, no doubt about it..."

Steven Plaskin, AudioStream.com, May 2015:
"...transient quickness and impact of the bass was greatly improved with the Grounding Block"
"...louder musical passages were definitely clearer with better resolution of transient detail using the Grounding Block..."
"...the Grounding Block not only increased the soundstage, but enhanced the clarity of Krall’s voice. The enhancement in focus and definition of her voice was significant..."
"...for those that have the financial resources to add the High Definition Ground Cables to the Grounding Block, the money will be well spent given the level of improvement provided by the combination of these innovative products..."
"...when I decided to write about the Synergistic Research Ground Block and High Definition Ground Cables, I thought that this would be a short review of products that delivered subtle improvement to the sound of my system. I was not prepared for the major sonic enhancement that these products delivered. The extent of the positive enhancements goes far beyond merely those of a system tweak!"
