Positive Feedback Brutus Award 2017 & Audio Bacon Finest Cuts Award
"...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. That’s because proper grounding is a foundational element and is an essential part of any Hi-Fi system. 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 New Active Ground Block takes the award winning UEF Ground Filter from the 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!
Four different models are available:
Active Ground Block 120V w/Black UEF power cord - $1995
Active Ground Block SE 120V w/Atmosphere power cord - $2995
Active Ground Block 240V w/Black UEF power cord (Schuko or US Plug) - $2195
Active Ground Block SE 240V w/Atmosphere power cord (Schuko or US Plug) - $3295

HOW IT WORKS
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. Synergistic Research’s Grounding Block was developed with many applications in mind and is one of Synergistic Research best selling product to feature the UEF Technology.
REVIEWS for the original (passive) Grounding Block:
Howard Kneller, UltraAudio.com wrote (March 2016):
"...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..." CLICK HERE for more information
Mike Girardi, The StereoTimes wrote (Dec. 2015):
"...the addition of the SR Grounding Block and HD Grounding 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 HD 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..."

"...the SR grounding block is impressive. Would never have thought I’d get that much more out of my system..."
"...I wanted to let you know that I was able to get the grounding block and cables set up and am very impressed. Previously I thought my noise floor was absent. There now exists an improved focus, depth and overall holography. Instruments, well defined within the room, immerses the listener into the music. The improvement is not subtle..."
"...I listened last night with the Grounding Block and, wouldn’t you know it, all the aspects of the advantages of grounding have come to fruition. Ease. Definition. Three dimensional. Reduced noise/glare - which I really noticed on some high note frequencies on particularly difficult CDs. Great."
"...it’s safe to say that the grounding block provides the best value for money in performance. It surpassed my expectations. The amount of detail I can hear now just wasn’t there before. I did plenty of listening sessions with it plugged in & out. With it plugged out everything just becomes dull but when it’s in the magic comes back :)"
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!"
