A New Ground -- Benefits of introducing the Synergistic Research Active Ground Block SE


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. They incorporate a range of the latest SR UEF tweaks

While the blocks alone are quite expensive ($2995) you will also need to lay out for connections to all of your components -- ideally the HD links. In my case as I have two distinct zones in my system I needed two ground blocks and 13 links -- quite an outlay

Question is is it worthwhile? Most certainly yes. The impact of implementing a full grounding solution in my system was one of the most profound changes I’ve experienced. It’s not a change that can be described in the usual audiophile terms of dynamics, frequency response, transparency etc. Instead it’s a shift in the wholeness, the verisimilitude, the gestalt of what you are hearing. Probably this is most obvious in a couple of places. Firstly is in background washes of sound (e.g. classic synth backings, or massed strings, or the whoosh that opens "Private Investigations") -- which now take on a scale, texture and clarity that had previously been completely masked. Secondly in vocals where a whole level of shading, nuance, breathwork, and subtly inflections are now audible. This is not simply more "detail" or a "reduction in the noise floor" it’s as if things which you did not know previously existed are suddenly there, as they had been all along

The effect is enhanced the more things you ground -- obviously all active components but even stands (my GPA stands are conductive so I connect a basic ground link to the bare metal inside the stand posts -- the surface metal is varnished and non conductive).

While I obviously can recommend the SR products I imagine any ground solution will bring similar benefits and would strongly suggest that anyone with a high resolution system explore some form of ground solution

@atmasphere , Ralph, I understand when you say that all components must have the safety ground wired to the chassis, which in turn is grounded to the ground pin of the AC cord. When connected to a properly wired circuit box with separate ground and neutral, there should not be any grounding problems.
Two questions; will all components then have the same ground potential?
Star-grounding a component is an improved grounding technique, but does it change the ground potential from a traditional component grounding design as stated above? 

Thanks @folkfreak . So, the active SR system is for SQ and most likely lowering the noise floor. It does not affect the ground of a component with an inherent grounding issue.

Thanks @whart . The Granite system is doing exactly what Ralph stated; attempting to correct the grounding of components that have an internal grounding issue.
Possibly plugging a component into one of the star-ground inputs lowers it's grounding impedance to get it closer to the other components' ground potential.

1: They better!
2: It better not! The reason is there should be no current in the ground connection.
Thanks. Your answer confirms what I thought should happen.
