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

What is the difference between the SR Active Grounding Block and the Active SE? Just the power cord?

They both appear to be current models. The difference is $1,000. From the pictures on SR website, they look the same to me.

Thank you
As well as the power cord there's also an "Active EM Cell" in the SE model -- I've never done a head to head comparison so have no perspective as to the incremental benefits of the added cost.

My recommendation would be to get a start on grounding with a model that suits your budget and spend the extra on better ground wires rather than the unit itself -- the benefits of using the SR HD cords (or having Mike Powell at Verastarr make up cables for you) is substantial over the (frankly) useless basic cords and the money you spend on these will pay back if/when you upgrade the ground block itself
Thank you @folkfreak !

I am seriously considering the Active SE, but the added cost of HD cables (I need at least four, possibly five) is holding me back.

I checked Verastarr webpage, they mention nothing about these cables. Maybe I'll send them an email to inquire about cost


Yes -- Mike makes the SR type ground cables to special order but the quality is good and the pricing fair (about half of what SR ask for their HDs)

I will share my experience of comparison. I really appreciate SR Active Ground Block SE. But in comparison the cables got the best sound in combination:
