Even though the SR Grounding Block was engineered to improve ground performance on our new Atmosphere Series Level 2, 3 and 4 interconnects and speaker cables as well as all SR products with external ground plane connections like Galileo, Tranquility Base isolation platforms, FEQ and Atmosphere wave generators, we have adapted it's use to include virtually every component in your system. Now you can drastically improve your entire system by "star grounding" to lower noise and allow all your music to come through.

Review

"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."

"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."

Review

"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”."

Review

"Synergistic Research has become a market leader of innovative audiophile products."

Review

"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."

Review

"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."
