Dedicated ground solutions are not a novel idea but over the past year it seems everyone has been coming out with their version. For a few months I've been thinking about introducing one to my system and had considered Entreq, Telos, Nordost and others. Although I have a bunch of Synergistic Research (SR) kit I had dismissed their older basic ground block as too rinky dink -- however when I heard about the new Active Ground Blocks I thought that could be the way to go. The Active Ground blocks are smallish devices with a mains connection and a plethora of outlets for grounding cables to every component. What do you think is the best?
The problem with grounding is pretty basic but the solutions may or may not be. To me, if I can put all equipment close enough together to share a common single-point ground, then that's what I do. But if any part is far away, then the systems need to be isolated rather than trying to connect the grounds. A good ground connection can't have a long conductor separating components because there is a potential voltage drop along the conductor. So the only good way to connect distant equipment is through some method that isolates the systems, e.g. using optical or electro-magnetic couplers.
