Where it all begins.
We designed our original Basic Ground Wire in 2015 to be high performance while offering exceptional value. Fast forward over five years, and we have advanced the state of our art with new technologies that improve nearly all aspects of cable performance, including discoveries we could not have dreamed of five years ago. With this in mind, we set out to completely redesign the original Basic Ground Wire with new technologies and materials initially developed for our Foundation Series cables, as well as our brand new state-of-the-art SRX cables. The Foundation Ground Cable starts with a Silver Matrix Alloy in a PTFE dielectric. We then incorporated a new woven jacket from our Foundation Series cables to reduce unwanted conductor resonance and static charge build-up. Shielding got a new UEF Compound originally developed for our Foundation Series cables applied in a Matrix pattern to the outside of the cable for a lower noise floor and enhanced musicality. Lastly, we use a new Three Stage High Voltage conditioning process first developed for our upcoming flagship SRX cables to increase the soundstage scale with a more three-dimensional presentation. All told, these effects are anything but subtle. So if you think a ground wire is just a ground wire, you owe it to yourself to audition a set of Foundation Ground cables with your SR Ground Block and rediscover the art of being well-grounded.

"One of the most significant effect results of reducing the noise floor and signal compression via the SR AGB SE allowed me to listen to music at much lower volumes without any loss of detail, silence between notes, and dynamics. Component changes alone have never resulted in the type of improvement the SR AGB SE brings to the table. With the SR AGB SE installed I was more engaged with the music and not left searching for it. The SR AGB SE is an integral part of my reviewing system. Highly recommended."

"The Synergistic Research passive Grounding Block and Active Ground Block SE have become an indispensable part of our systems. It improves the sound in a way where component and cable swaps just can’t mitigate. If you want to maximize the potential of your system and experience fresh musical highs, we have no hesitation in recommending either of these Synergistic Research grounding blocks."

"The resulting impact of these three products is more than the sum of the parts. By that, I mean that with these devices it’s more of a “1+1+1 = 5” effect. The noise floor drops significantly, and with that, I feel like I am hearing everything my system was designed to perform. Honestly, I wish these three devices did not matter as much as they do. It’s a new can of worms to unravel and makes system setup a lot more complex. However, I would never go back to an “untreated” system. The new system sounds more dynamic, more detailed, more lifelike in the soundstage and timbre of the various instruments. In short, it sounds more musical, more real."
-Lee Scoggins - Part-time Audiophile - September 2018
"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."
"you would be hard pressed to find a tweak, at this price point, that gives you better bang for your buck. If there is a better grounding solution available for audiophile systems at this price, I have not encountered it yet! That being the case, it was an easy decision to make it a part of my reference system."
-Malcolm Gomes - Positive Feedback - April 2019
"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”."
"Synergistic Research has become a market leader of innovative audiophile products."
"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."
"It certainly made a difference in our test room, making the system seem more organic sounding, more focused, with a bigger soundstage, and a significant reduction in low level hash."
