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

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:

Synergistic Research High-Def Grounding Block Cable - for source;
VH Audio UniCrystalTM OCC SILVER 24AWG - for DAC’s;
Duelund 1.0 - for SR Base and Amp’s
The Active Ground Block SE has an Active Electromagnetic Cell similar to what is found in our PowerCell line conditioners, the non SE version does not. This (the Active EM Cell) filters high frequency noise out of ground which is significant. One of the subjective effects is a boost in low frequencies where your system sounds more powerful and controlled in the lower registers. As to HD Ground Cables it depends on what else you've got in your system. In an otherwise all SR loom of cables they are far better than the VH Audio and Veristar cables which sound muddy and lower resolution in direct comparison. If you've got cable stew who knows, that's like putting four different rims and tires from different manufactures on the same Ferrari. The same goes for the power cord, in a full loom of SR cables the supplied power cord will sound best. Also NEVER plug an Active Ground Block into anything but the wall. Repeat NEVER EVER plug the Active Ground Bock into anything but the wall. Do NOT plug it into a line conditioner or anything but a wall outlet otherwise you will introduce impedance and crosstalk contamination and this seriously diminishes sound quality.

Thank you, Ted.  I was looking for this answer.
I have a duplex socket on the wall where one is plugged to a conditioner, and the other socket is not used. Can the AGB SE be plugged into the unused socket?
