Entreq Ground Boxes & Cables

What they tell you from Vitus, is exactly like what the Constellation technical service told me: If I plugged the negative terminals of my amplifier into two Silver Minimus boxes, the amplifier, "kaputt".
Frankly I did not understand it, but I still did not dare. Until a guy from WBF sent a picture of his stereo Centaur, with the terminals connected to two Silver Minimus boxes, then I decided to do it. And ... nothing happened. Well, something happened, my system sounded better. Many manufacturers hear the word Earth, and they no longer want to hear anything more than you explain, say NO.
On the other hand I have to say that in my experience with Entreq boxes, the connection of these to free signal outputs (RCA, XLR, USB, RJ45), has always improved the sound. However, this has not been the case when I have connected the chassis ground terminals (on those devices that have them).

Yup. I heard the same BS too when I wanted to try one. Like you, just got better sound.

I wonder how many people have blown up their gear because they grounded things that should have never been grounded? We probably don't hear those stories just like gamblers only tell you when they win.

That plus how inserting an antenna in your system decreases emi

Lots of unshielded antennas here:

you can kill or maim yourself with a hammer. but you'd have to be pretty stupid. it's a tool that requires proper use....and basic common sense.

Entreq gear is not a problem to use, it does require common sense....and it is not just casually plug and play. but used properly in an appropriately sorted out system, it does improve performance.....in my personal experience. YMMV.

I use my Entreq Poseidon and -3- Atlantic Minimus boxes (as boosters) to ground the negative terminals of my dart mono blocks, plus ground my bass tower amps. makes a significant contribution to performance.

as I recently got a Tripoint Elite for my sources, and moved my Tripoint Troy Sig to chassis ground my dart mono's + ground my passive main speaker towers, i'll be moving my Entreq Silver Tellus across the room over to my Studer RTR decks.....as the Silver Tellus is redundant on my other sources now with the Tripoint Elite in that spot.

Well, there seems to be exactly what Entreq says there is; a mixture of minerals whose formula obviously do not publish.

Well the best simple definition of 'ground' is:
That 'ground' acts as a common reference point.

From the descriptions of these boxes that I have read, they don't act as a common reference point.

In fact the boxes don't meet any definition of 'ground'.

So it's hard to image a way for them to blow anything up.

In the cases where they are connected to RCA chassis jacks that have plastic insulator rings, the box & wire can act as an interference antenna.

I wasn't strictly speaking about the Entreq boxes, but more to the point that we have some people who are bereft of electrical knowledge who now think everything should be grounded. And if the Entreq boxes aren't really grounded to ground, what are they doing? Are we floating ground now?

From an electrical engineering perspective, they arn't doing anything.

What does this mean?

Yes, we can float an audio circuit common from an AC power circuit Safety Ground.
But the basic definitions for ground are:
a] Common reference point.
b] Path to such a point.

Most of the boxes don't meet these definitions, but I recall seeing one box that did. (it functioned as a terminal strip for several ground wires)

My understanding about the possibility of some connected amplifiers failing is if the ground box connection points are truly common and are wired to the negative output terminals of a stereo amplifier which are not true circuit grounds could result in blown outputs.

I don't know if we are arguing semantics now. Voltage is referenced to ground and you either have a true ground or you don't. So I don't understand how people are connecting a ground wire to a device that is not truly grounded and somehow they think they have now established a "better" ground.

I don't know, but I don't believe the for the most part the terminals are commoned together. That is they don't have continuity between the terminals.

Not semantics, voltage is referenced between two points, one of those points may also be 'ground'.

What is a 'true ground' and what is it's function?

There is a warning on the Stillpoints website:

"You must use one Ground box and one ground cable per channel! Never use a single ground box to connect both channels. You will likely damage your amplifier."

You can use one Poseidon which has three independent ground terminals.
 
Nordosts’ brand Q Kore is similar and provided an amazing change in sound for me. The unit provides two paths; distribution and components. I have only installed this on the component side, but will do the distribution side this upcoming weekend.

I can only assume Entreq is similar in nature, and if it does close to what Nordost accomplished, it was worth the investment. Louder with a clear soundstage. I am really focused on power products to the various gear and room treatments as I have heard the difference; now my newest part of the hobby.
