Synergistic Research Ground Block

Small, yet powerful ground control. What if you could significantly upgrade your audio system without changing any of your components? Simply connect your system to the SR Ground Block and you will hear things you've never heard before. Even the most sophisticated electronics are transformed with a dramatic reduction in noise.

Music ushers forth from a jet black sonic background, with never before noticed detail. And modest components take on new refinement to perform far above their class with virtually every area of system performance being enhanced in dramatic and surprising ways. An unprecedented breakthrough that will forever change how you experience music at home.

The term “ground” refers to a connection to the Earth, which acts as a reservoir of charge. The high-speed, SR Grounding Block provides a conductive path for this ground, separate from the normal current-carrying path of your components, which under certain conditions can add up to 10 dB of noise if poorly designed! The ground path with the least resistance is the best path to Earth, and there is no better ground path for your components than the SR Grounding Block.

By cleaning up your system’s ground connection you hear a noticeable improvement in soundstage height, depth and width thanks to a lower noise floor. Soundstage scale is improved with richer tonal density especially at the edges of your sound field. Image outlines are brought into clearer focus while musicality and overall system refinement are greatly improved.

"...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 realised 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...”

“The SR Grounding blocks came in as well. 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.…. Certainly the Grounding Block knocked down some haze…no doubt about it.

…..the Grounding Block proved itself to be a fine, compact, and very useful system enhancer.”

"...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."
