Synergistic Research Grounding Block

Synergistic Research

$1,090.00 USD 

Synergistic Research's Grounding Block was developed with many applications in mind and is the latest Synergistic Research product to feature the UEF Technology.

It’s not a secret that a solid "Star" ground dramatically reduces the noise floor of any system. The development of the Grounding Block was a natural step to further improve upon Synergistic's already excellent Ground Plane technology, first developed for the Tranquility Base products.
Soon after the launch of Tranquility Base products, the Ground Plane technology was adapted in the PowerCell 10, Transporter Ultra SE, FEQ and last but not least in Atmosphere and Atmosphere Series Cables.

The primary, but not the only, application for the new Grounding Block is to connect the built-in Ground planes of our new Atmosphere Series cables, which are featured in Atmosphere cables from level 2 and up to level 4 of Interconnects, as well as in level 2 to level 4 of speaker cables.
The Grounding Block includes:

  • 4 each (4 ft) ground wires
  • 2 each (8 ft) ground wires 

That's enough ground wires to connect 2 sets of interconnects and one set of speaker cables to the Synergistic Research Grounding Block.
But wait... there is more: The Grounding Block will likewise improve the overall performance of your system, simply by connecting the ground wires from the following products to the Synergistic Research UEF Grounding Block:

  • Synergistic Research Atmosphere – Acoustic Field Generator
  • Synergistic Research FEQ – Frequency Equalizer
  • Synergistic Research Tranquility Base Products
  • Any Turntable Ground
  • Any Chassis Mount Ground


Optional ground wires are available with the following terminations:

  • Micro Banana to Regular Banana Plug
  • Micro Banana to Bare Wire

Available in 4 feet for $15 and 8 feet for $25.

SoundStage Reviewer's Choice Award

Howard Kneller,, 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..."

Most Wanted Component 2015 Award

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..."

PFO Brutus Award 2015

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 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,, 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!"
