"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 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."

"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."

"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."
