High Definition SX Ground Cables
Control is power.
Since engineering our original HD Ground Cables over five years ago, our understanding of building the world’s best-sounding cables has advanced exponentially. In areas such as metallurgy, UEF compounds, and high voltage and high current conditioning processes have collectively gone well beyond anything we could have imagined in 2015. So it was time we applied all we’ve learned to build the next generation HD Ground Cable. We started with the same hand-made AirString Geometry. We added a new single crystal pure six-nines silver conductor in an air dielectric for cleaner highs and a noticeable increase in resolution combined with a more relaxed presentation. We then add a new UEF Compound to a new Matrix Shield for an even lower noise floor in a more holographic soundscape. We then added our brand new Three Stage High Voltage conditioning process initially developed for our new flagship SRX cables for a dramatic lowering of the noise floor. All told, these improvements create a whole new level of performance, resolution, and musicality. In short, adding our new HDSX Ground Cables to your system with any of our Ground Block technologies will improve all aspects of sound, and not in a subtle way. Try risk-free in your system and rediscover the art of being well-grounded.

High Definition SX PowerCell Ground Cable
While an SR PowerCell incorporates many of the same technologies found in our Active Ground Block, the PowerCell’s implementation is necessarily isolated to the AC portion of your system. By grounding your PowerCell to the outboard Active Ground Block where all of your components and for SR cable users, their Atmosphere X and Galileo SX cable shields are all connected to a central isolated and actively filtered star ground point and this drastically lower your PowerCell’s noise floor. The act of uniting your active components including your power conditioner and cable shields to a central filtered ground hub improves all aspects of system performance in surprising and dramatic ways. This latest application for our Active Ground Block is highly recommended for all Synergistic Research PowerCell and Active Ground Block users.
"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."

My apologies for some of the hyperbole, but along with the Synergistic Research Galileo SX PowerCell, the Galileo SX Ground Block is possibly the most impressive new product that I have reviewed in the last couple of years. I have mentioned many times that the PowerCell might just be the most important component in my entire system. Now, there is some definite competition. Though each have different functions, both can offer something similar in terms of impact. Both provide a rising tide that can lift all boats.
With the Galileo SX Ground Block in place, I stopped critiquing the sound and was able to just focus on the music. As a typical audiophile, this is always a challenge. Bottom line. The emotional connection and level of personal satisfaction has never been better in my listening room! That's the biggest compliment that I could ever offer. If you are seeking state of the art performance, the Galileo SX Power Block is a must audition. Innovative design. Superb execution. Wonderful results. 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."

"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."
