Basic Ground

Where it all begins.


Originally the SR Ground Block was engineered to improve Ground Plane performance on Atmosphere Series Level 2, 3 and 4 interconnects and speaker cables as well as all SR products with external ground plane connections like Galileo UEF, Tranquility Base isolation platforms, and FEQ and Atmosphere wave generators. We later discovered we could dramatically lower any system's noise floor by star-grounding its components to an SR Ground Block. Imagine hearing your recordings again, for the first time. Recordings you've been listening to for years suddenly become new with information and emotional connection like you've never experienced before. This is not an exaggeration, but a reality when you ground your system to the Ground Block with Basic Ground wires treated with 1,000,000 volts of electricity in a process we call Quantum Tunneling which improves the the ground connection between the connected component and the Ground Block's internal UEF Inductive Ground Filter. Available in nearly every imaginable configuration including Ethernet, RCA, XLR, banana or BNC, we even offer a Basic Ground cable for mini-phono jacks so you can ground computhers and their internal circuits to the Ground Block for an absolutely unbelievable improvement in sound.

"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."

"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."

"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."
