OK so help be understand something. I understand the value of grounding equipment, but what is the value of having a woodbox with salt, earth, minerals etc do for grounding? How is supposed to work or be better?
If you google "groundside electrons" it will take you to a thread at diyaudio.com. This guy took 140 threads of 40 awg magnet wire. 1 foot each if I remember. He twisted these up into a litz wire (three twisted bundles that are the also twisted together). He put 3 short lengths of regular heat shrink distributed evenly on the wire. Formed loops by connecting both ends and cleaning off the polyurethane using a solder pot and soldered the ends together. He covered this loop in cotton sleeving and connected these to signal grounds on his stereo (most important) and chassis grounds and AC grounds. Too many worsen the sound. They're called Ground Loops. The effect takes time by slowly sounding better before getting worse and then better than the first cycle. If not used for months the entire charging or conditioning cycle is repeated. It was this changing of their affect that lead to them having any idea at all about how they worked.
They argued for almost 30 pages over these things. It took me several days of company time to get through them all. Long story short, here's the most likely explanation for why they work. When signal is rising all the electrons in the conductor spin in one direction and the electrons in the dielectric spin in the opposite direction. When the signal slows it's rate of change and then reverses its polarity all the electrons have to reverse their spin. It's theorized that this enormous surface area of dielectric is the key. God help me I'm trying to explain this and I have no idea how it works. Okay. Start over. Imagine Hillary having a love child with Kamala and that demon possessed mutant screaming at you all the time. Well, it's like these kill that virtual monster child and your system sounds way better.
These work on most systems but on about 10% to 15% they do nothing. The systems unaffected are usually super expensive and have over built ground planes. Therefore, it seems likely that there is a shortage of electrons in the ground system that these loops provide. Electronics work by sucking electrons off of the ground plane (there's more physics to it than that but for this discussion that's all there is). So you could either put a thick plate of copper in as a ground plane or these loops. I've read up on the electromagnetics of this and nobody talks about electron spin and especially electron spin in the dielectric. And what about having zero electrons in a vacuum and getting better sound. Or vacuum capacitors.
Some people have tried doing this using 9 volt batteries hooked across capacitors. Then attach the positive of the capacitor to any grounds on your system starting with the most sensitive which are the signal grounds at the source component. There's some info online about this. They don't have the capacitor size worked out yet. I tried it since I had all the parts already. In conclusive. Seems to add some liveliness at first but leads to brightness. Maybe my rig will never respond. Maybe I should buy some loops to try.
Gotta go. I think we should experiment and pool our knowledge on these DIY ground boxes. I don't want to spend 10 grand on one and be stuck with a particular sound. I searched for used units on hifishark and found there were a lot of them for sale near me. I wonder if that should be taken as a warning?
Shungite is a rock that has a lot of carbon in it and a smattering of metals. I bought some recently and got my hands dirty handling it. So I washed it and put in the microwave to dry. Sparks flew out of it similar to sparkler sparks. Nothing too alarming though. Shungite is famous for containing Fullerenes like C60. It's used by naturopaths to condition drinking water. You soak so much if it in a certain amount of water for 2 or 3 days before drinking. The shungite is used up after a few months and discarded.
There's another thing called a Counterpoise. It something that's used to create a synthetic or artificial ground for short wave radio operators who cannot obtain a physical ground. I looked into it. It's like a large net that is able to generate some sort of EM interaction with the atmosphere. Of no use to me as far as I can tell.
So now I think we can get down to different designs for ground boxes. I'd say the primary type would have the majority of the material being carbon based. Either shungite or charcoal or even carborundum if you're loaded. Or a mixture. You can buy activated charcoal by the cubic foot from water treatment places and it's fairly cheap. Not sure if there's a benefit. You can also get barbecue charcoal made from South American hardwoods that is super dense for charcoal.
Then you'd add a sprinkling of quartz or whatever piezoelectric material you chose. Considering the number of these things that are ceramic based maybe more than a smattering of piezoelectric material is better. For quartz, I dont understand why you couldn't use play sand. It's not quartz but it has to have some crystallization and is dirt cheap. They sell quartz sand for salt water aquariums but I haven't contacted the company to see if it's real quartz. If it is I'd be trying that by the bucket load.
Ferromagnetic would be soft iron shavings (maybe oxide so it doesn't rust), tungsten and nickel. I don't know about tungsten oxide or nickel oxide. I do know they sell soft iron oxide powders for teaching magnetic fields in school. Then there's magnetite too.
I have no idea why it needs to be a wooden box or why the copper box inside would benefit from being really thick. Is hardwood better than plywood? I never read that the wire probe going into the box should be short and thick.
The secon type of box would be charcoal/carbon and salt based. Sounds to me this is working through ionic transfer of some sort. I have no idea why the carbon is needed. Then we have the commercially available products that are a pre-engineered using science. I've seen one small tweek device that is think worked like this but where do I buy a huge brick for cheap?
Them we have the salt water battery type device. No ones made it yet. It was just a suggestion by a big brain on a forum.
I was talking to someone that saw inside a base level Entreq damaged in shipping. It was basically a box of thick copper plate (price that stuff out - yikes!) with the terminal lug bolted to that. Most of the filler was a black rock (Shungite, I'd guess) and sprinkling of various metals that looked like copper, silver, iron fillings etc. This guy uses an Entreq and no power conditioner. He said the various models and generations sound different (they basically give it a warmer sound and lower noise floor). I have no idea what his system is. I asked him about the Telos GNR. It's an active unit from Hong Kong. I'd like something active because to me it should be adjustable in some way. He said he'd heard that unit and it worked but not as much as the Entreqs.
That's part of the reason I'd like to try making one out of salt water in a water fountain container (5 gallon plastic jug). You could change concentrations or salts.
And can anyone tell me why these have to be in a wooden box? Why cant I use a plastic pail or storage container? No body mentions this. If this works I'm going to have a lot of big ones. An over sized one for each component.
Before I try to make conclusions I need to digress some more. Acoustic Revive makes a power conditioner called the RTP. It's made buy CNCing a pocket out of a solid block of aluminum. The minimum thickness is 1 inch. It's basically a power distribution block more than conditioner. They pour green carborundum on the bottom then take a fine grain mixture of a specific type of tourmaline and quartz and mix it with epoxy and pour it over the carborundum. Green Carborundum is actually a brand name. It's really silicon carbide. So we're back to silicon and carbon. This compound doesn't exist in nature. It's used for sandblasting and is being researched for EMF sheilding in harsh, high temperature environments.
As far as I can tell tourmaline is just quartz with a bunch of other elements mixed in. I think they were using black tourmaline but not sure. I don't know why they aren't using Rutilated Quartz instead. It's quartz with a bunch of metallic elements embedded inside it. Maybe tourmalines are more consistent?
So that's the Acoustic Revive. Add wires and AC receptacles.
The CAD is supposed to be basically the same type of thing but sourced from a scientifically engineered and developed product. I think it was a ceramic blend. It's not lose. It's cut from a block. Whether it's rubberized or brick like I dont know. They said it's the same as or came from the same technology as used to ground aeroplanes. I looked into it and found nothing.
Tara Labs, the cable maker, uses a proprietary ceramic blend to ground their cable shields. That sounds like a good idea. Usually shielding analog cables is thought to reduce air and dynamics etc. Generally a bad thing so if you can get the benefits without the negatives I'd be all for it. I talked to a dealer recently who warned me away from their cables. He deals in the very best gear so I'll take his word for it. Walked away from a $3000 used cable on his advice. Gotta trust the few who know what's really up.
I found this thread looking for info to build my own ground boxes. I wanted to make comments and ask questions of the people with experience but thought it would be meaningless on threads inactive for almost a year.
Firstly, there is so much misinformation in this thread I can hardly believe it. Lightning is the number one reason for a safety ground but it's not the only reason. Admittedly it's a complex issue the I dont fully understand. See Grounding and Shielding 4th ed. by Morrison.
And if anyone hasn't heard Ground Boxes and thinks they're snake oil they ought to keep their comments shorter. People are leaving sites like these in droves because it has become a waste of time.
I don't know how these things work. But we theorize anyway. I know how interconnect is supposed to work but I know interconnect that breaks all the rules and sounds even better. I've been experimenting with various wire types on my system and the area between the conductors makes zero difference to the sound. Its supposed to make a huge difference because it's the"loop area" that determines inductance. I've learned the hard way to trust my ears and not reason with incomplete scientific models. I don't ignore them, just am not ruled by them.
The first time I heard of Ground Boxes where I actually paid attention was the OCD Hifi Guy video. Since then I've spend a lot of time looking into it. I almost broke down and bought a used one.
Like Mikey says there are Ferromagnetic, Paramagnetic, Diamagnetic and Piezoelectric materials. You can research that yourself. I'm not going to rewatch the video but I thought he said he used a base of dirt. If so I have no idea why.
Audiogoner tksteingraber said he researched ground soil mixtures or something and they used charcoal and salt. I had never found anything previously about that and searched it now. It looks like they also use calcium chloride (and charcoal). It said that concrete "dopes" the area for good ground. It attracts moisture and provides plenty of icons. Now I know why soil next to concrete is so cold and moist.
That's a different thing than a ground box. I'd imagine that on most ground box designs the moisture and ion levels do nothing. On ground boxes that do use that than it is actually how they work. I read somewhere that making a salt battery might work. I wish I knew chemistry better so I'd know exactly what they meant.
Okay. So we have all these elements. Carbon absorbs certain frequencies of EM (Electromagnetic) energy and converts it into heat. Quartz is crystalized silicon and highly piezoelectric. It converts EM energy into physical vibration. Damp that vibration and you've converted that energy into heat as well.
I'm writing this on my phone so will do several shorter comments so I don't lose anything which would be a waste of my time.
I have a friend that purchased an Entreq Poseidon and swears by it. He says it makes his system sound better. I have also been dabbling in making one of these for myself. Trying to find out what’s in them is like trying to get the recipe to Coca Cola! I did finish mine however and installed it on Saturday on my system. After about 20 minutes I was able to hear a bigger soundstage and much better imaging. It made my speakers disappear in my room.
I shown some photos to a cousin of my studying mineralogy at university of the so call special mixture of the Entreq.He said it look like Black Iron Oxide.Sells for $100 for a 20kg bag. .Entreq sells the cheapest unit for around $800US.I shown him the ads about magnetic balance with minerals contents and he laughed.
^^^^Cost may very well be the ultimate determining factor for some but it’s worth pointing out, all artificial ground circuits do differ when it comes to details (impact) which may lead to us choosing one manufacturer over another. I highly recommend trying atleast 2-3 artificial grounding options before you settle with a brand that sounds the best in your system.
Someone with a grounding box: What is the voltage differential measured between the grounding box and the "D" hole, the safety ground on a wall outlet? Curious to see if a voltage can be seen between the grounding box and the earth ground of your home.
Odds are @twoleftears , it is just Y-capacitors connecting the two terminals together. They are a type of capacitor that fails "safe" ... i.e. it does not form a short, but stays being a capacitor.
Puritan has a unique approach to extra grounding. http://www.puritanaudiolabs.com/products/ground-master/ Despite possible appearances to the contrary, whatever they are doing passes all the British safety code electrical standards.
I'm not going to read through all the responses to this question but the OCD Guy video if anyone actually watched it says straight out that the box he built and I'm not sure that he actually sells them is not a replacement for a proper ground system outside your home. He actually has a video( https://www.youtube.com/watch?v=B9RPE4gDYCM&t=2s ) showing how he installed his power and ground. Plus he shows the inside of the Cohiba cigar box that he used to make his ground box. Very simple and he is the first one to state that he is not going to go in to some pseudo science on why it works. He states that for someone living in a second story or higher apartment, residence that it may work if you cannot install a proper outdoor system. As for the expensive Swedish stuff and the rest, I won't call them quackery (but that's what I kinda think) because I had dismissed other ideas, tweaks as ridiculous that I don't anymore. Watching the OCD Guy's recent video on analog/digital comparison; outside of a dealer demo, the best video that I ever saw.
I cannot say whether or not any improvement from using one of these grounding boxes is "worth the money," but for some context, I thought the Nordost system made a bigger improvement in the system my local dealer used to demonstrate the product (high end system) than did power conditioners or high end power cords (as compared to decent but not extremely high priced cords). The improvement in clarity and soundstaging was quite impressive.
5:00 am in the morning until 2:00 am the following morning, the
electrical is extra noisy. 21 hours of the day and night, I might be

Your house sits at the end of a long wire, i.e. inductor. That wire is connected to a transformer (inductor). It is also connected to a wire (inductor). That is in your neighborhood which is actually quieter from 5am - 6pm.
Yes, there can be more harmonics on the line during the day, but those are low frequency harmonics, i.e. in the KHz, low 10's of KHz. All the high frequency noise, etc. from industrial never makes it through the wires. There is too much parasitic inductance and capacitance.
Well heck that explains it all, silly me.. I don't want to get rich, I don't want to be poor either.. I just want to have a good time.
Do you really think these people can't hear an improvement or difference with CAD?

Remember it was the mechanics that got the boys THROUGH the hedge rows after D Day.. Not the guy that said "We'll have to go around, that's the only way", lookin' down the barrel of a Super Tiger Tank. Those mechanics were straight off the farms in agro America.. They were makin' moonshine and making sure America and half the world ATE..
I say this with total respect.. Engineers, build the stuff, BUT mechanics keep it going...NEVER an engineer in sight.. Civil Engineer, every now and the.. just to keep it "Civil" that is...
Now once again.. Figure out how to make it work.. I know the CAD system does work.. I just want an Earth Box NOW!! I was thinking about it before. NOW I will have "The Box"...
After further research, we know that chassis ground (or electrical ground) is not the same ground that is provided by these "Passive" (wood box mineral) or "Active" (AC powered) Nordost, Synergistic Research, CAD devices. These devices, passive or active, provide a Signal Ground.
I can see value to these devices, but assuming you can provide a "low impedance" ground separate from your house electrical system via ground rod would essential provide a signal ground, correct? or would these devices be a better option?

Just trying to wade out of the brown stuff oldhvy, but wow it is piling up deep. Audiophiles are no different from any number of other endeavours where people convince themselves of things that are just not true and then defend them vehemently. Remember the 200MPH carburettor. It was the man (big oil/car companies) keeping us down! Nope, it was physics. How about that box you add to your incoming AC that reduces your electricity bills 30%? Lots believe that and still buy them. How about a mat you put in your electrical panel that causes your refrigerator to start freezing (thermostats be darned).
All these tweaks are the audiophile equivalent of "get rich" schemes. They are a substitute for hard work.
As far as I know, the ground provides protection from high voltages and provides protection to the equipment. If you have a direct lightning strike your out of luck regardless.
Equipment ground will work without a grounding rod, like oldhvymec wrote the grounding rod is for over current from outside your home. Audiophiles that use isolated grounding rods are actually putting themselves in danger because if there is a fault in a circuit some of the over current could go to the isolated grounding rod and then the breaker won't see an overcurrent and won't trip.
If it looks like ... And it smell like ... It probably is ...

I don't know how someone who has an engineering degree can write that trollop, but given his expertise is in "digital", maybe he just has no clue what he is talking about.
you stated "The grounding rod to you electric service is for lightening strikes, it has nothing to do with grounding your components."
Perhaps you can elaborate on your comment?

The CAD grounding box range is considered the best in class by many in the industry. Stereophile gave it a 2020 award after a couple of their staff found great results, including the often hard-to-please Michael Fremer:
I would urge people to try these CAD ground control units. The differences are very evident. I had a home demo and ended up buying two the effects were that good.
I require Hallographs (pair behind speakers and pair at rear of room) despite my high end custom listening room. My speakers are not SOTA or close to it (Legacy Focus) and require help in focusing imaging, soundstaging and frequency eveness. The Hallographs tune the acoustics making these speakers adequate for my use without purchasing big bucks speakers I’m looking at ($35K to $60K). My future speakers may not require Hallographs and probably won’t need speakers' SR HFTs either (the speakers I’m entertaining have multiple bass and treble controls built-in). I haven’t tried grounding boxes. It won’t hurt to try.
@millercarbon Nice explanation of RFI and grounding conditions affecting equipment/cabling.
The Nordost grounding box makes a huge difference, really & I mean VERY noticeably cleaning up the sound (the extent of which surprised me, I didn’t go in open-minded) - but they make no claims to stuffing it full of minerals etc. Used can be had for biggish discounts. There are 3 units in 2 ads on AG at this moment. I wouldn’t buy anything stuffed with minerals unless I heard it, especially side by side with a Nordost. I trust my aural memory enough that unless I heard a huge improvement w/o a comparison, it’s (very) unlikely to be as good.
@cakyol, Incorrect. Ground lifting and grounding boxes are two different things.
Though I am not versed as to how the other manufacturers connect their equipment, I do know that the CAD unit uses an unused input to connect to the grounding box. This essentially grounds the equipment's circuit, not just the chassis. B
There is something called a ground lifter, which in a few bucks achieve exactly the same purpose and grounds your system as well as eliminating any possibility of hum arising from ground loops.
It is probably trying to simulate that, but at a price tag suitable for audiophools.
This has been very interesting. So the wood boxes full of crystals and other minerals provide a ground. If you could help me understand it better I know that ground is usually referred to as negative in a circuit but as a zero-volt reference point potential for a real ground. So how scientifically is this box of elements act as a ground? Why these minerals and not just a box of dirt? Do they provide a positive or negative reference?
@ozzy Thanks for that comprehensive answer. Very generous of you to expose the secret sauce that's inside the boxes. Interesting that the YouTube guy used your design, including the cigar box.
@ozzy Reading the basics about the Synergistic Research box I discovered they use the signal ground, not the earth ground from components. Is that what you are doing?
Crystals? Iron Ferrite, crushed magnets? I keep reading about magnets. How they can DIRECT and focus a signal to the CENTER of a conductor... Don’t shoot the messenger.. It’s how they focus a laser in a vacuum.
Rick Schultz at High Fidelity Cables has been using magnets in his cables and devices for years. The magnetic field directs electrons into a more direct path (or something like that).
Where do you get this at ozzy? What I found is really expensive, you got a source? I had to haggle like crazy to get it at 18.00 usd 100mg vials and buy 10. 180. for a gram of dry graphene.
What about salts? There a ton of different salts.. ay?
Crystals? Iron Ferrite, crushed magnets? I keep reading about magnets. How they can DIRECT and focus a signal to the CENTER of a conductor... Don’t shoot the messenger.. It’s how they focus a laser in a vacuum. A type of signal focal thingamajig. I’m thinkin’!!!
A U shape copper grate in a magic solution, that SUCKS out bad mumbo jumbo..
OK GUYS I’m headin’ out to the shop.. I’m gonna make one.

Just no plug ins, all screws, nuts and binding washers.. 12.00 for a copper bar.. and all the wire.. I’m heading for the drill press..
I need to start a thread.. Say OP you gonna do one up? make an Earth Box that is?
Who is gonna do it? I will.. NO I'm not a sucker.. I can watch it rain, or work in the rain...:-)

aubreybobb38 posts01-27-2021 8:10pmI use the synergistic Research active grounding box.
<<<<<<<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>>
Why is it active? I see it is plugged in. Is it just plugged into the ground of everything? Like the "Earth Box"? You see why my gears are grinding???? Very interesting..
I use the synergistic Research active grounding box. When it was accidentally switched off the other day (very tiny light) I spent the day wondering why everything sounded flat...the 'life' seemed to be missing.
MC gives a very plausible explanation. More importantly, his point of criticism without experience being foolish, is wholeheartedly endorsed. I don't mind when there is humour, but those who 'know everything' without 'trying anything' are a pain.
@OP, I have auditioned grounding units, though not the one you reference. I listened to the CAD ground control at Audioconnection, and both I and ctsooner noticed a significant change in the background. It just seemed 'blacker', and you could make out subtle details in the music that you didn't notice without the CAD. I, for one, don't put a lot of faith/money on these things, but I have to believe my ears when they do make a change for the better. Bob

That is a pretty interesting view MC, I'm going to add optimistic, BUT I'll buy the plausible, all the way.. I'm all about the tweak, to a point. I'm out of there when the ol "Necromancer" and the chanting begins though..
IF I could bring myself to build the thing and give up one of my prize cigar boxes, that is the only question left.
I'll give it a shot, what do you think, I got Goat shi$, Chicken shi$, rabbit shi$, dog shi$, shall I go on.. Oh Oh and a nice big quartz dead center of that U shaped conductor. Where does it go once it's collected a load?
Filter change every now and then? Though I jest, I'm serious, VERY serious.. I guess it's a filter (collector) of sorts.
I'm thinkin, liquid, how conductive is that? Say H2O ph 6.8 ROed. I can't use the cigar box can I?
I think the whole star ground DUMP is a great idea. I think it should still be tied to the House earth bonding, AGAIN what stop it from going backwards... Does it suck it out? MC you say the floor is uneven, ok we need a floor drain, right? What makes it go that >>>>>>> direction, and not <<<<<<<<<< direction?
Why does it go into that box and not come back out.. I'm a mechanic.. It has to be plausible, OK...
@millercarbon, I hope you realise I was serious when I asked, where's MC. I know you think outside the box and might have a theory.
Now my question, how do we know that the box only contains dirt or sand? Could there be some of the elements used by Bybee and other "snake oil" developers?
All grounding schemes from component to earth have different levels of impedance (ground potential). We know this much.
By no means am I an expert, but by wiring each component’s chassis
(earth ground) to the grounding box and adjusting the settings, the
theory is that an equal impedance to ground can be achieved.
"How?" is the refuge of scoundrels. "Does?" is all that matters.
Don't take that the wrong way. Not saying "how" doesn't matter at all. But we all know, or should, the tremendous number of people who use "how" as an excuse to avoid even trying to find out if it "does". Not to belabor the point but instead of simply trying and listening and finding out they dig in and fortify and argue to the death, never giving any credence to the fact a whole bunch of people are saying yes indeed it really does work.
The hallograph thing right now today is being ridiculed by one of the prime examples of closed-minded foot stamping on the ground stubborn insistence we prove "how" before he will even consider "does". That is what I mean by scoundrels.
The hallograph, the ground box, and a whole bunch of other seemingly silly stuff all have one thing in common: they are plausible. That's not saying they DO work, but rather that if you know enough about the physics and electronics of sound it is easy to see how they COULD work.
We never do prove if something works by thinking and talking. That is the realm of scoundrels. We prove if something works with testing by trial and error. The exemplar of a scoundrel is georgehifi. The exemplar of a tester is Chuck Yeager. I trust at least some of you are able to discern the difference.
So how exactly is it plausible for a box of dirt to lower the noise floor? Well, lowrider57 is right. Just please don't shoot me over it.
The way I think of it, the environment is saturated with all sorts of electromagnetic radiation. We like to call it RFI but the R stands for radio and that means megaherz but electromagnetic radiation spans a spectrum it is not all radio frequency so I like to keep an open mind and think of it as just plain old electromagnetic radiation.
Now if you know your EE101 then you know whenever any electromagnetic field crosses a wire it induces a current in that wire. This is how transformers, generators, phono cartridges, etc work. Happens with every wire. Every bit of metal, really. Every wire and metal in your system then is like an antenna channeling noise into your music.
So that is one way the earth ground box can work, as a sort of drain for this unwanted noise. Think of the noise as rain. The more drains the less water on the floor. Most of us have a great big one right in the middle of the room. That's your normal earth ground, the 3rd prong on the plug. Doesn't mean a little one over in the corner won't help.
But then we have the problem of the floor never being perfectly flat. The slope of the floor is impedance. If the floor was perfectly flat, the electrical impedance, the resistance of this tiny current going to ground was perfectly equal everywhere, then we could use lots and lots of drains no problem. But it is not. Some floors slope every which way. When this happens if you have more than one drain you get water (current) sloshing around and what do we call that? Everyone all together now: ground loop hum!
But there's another less well understood way the earth box could work. Notice some of these boxes they are telling you to fill them with different minerals and stuff. There's people like mahgister putting rocks on wires. What is up with that? Are these things related?
I think they are. Certainly plausible. Remember, the signal is not just in the wire. It is a fluctuating field. It emanates all over the place. These probably are all nothing more than different ways of tuning, or what mahgister calls embedding, the system to its environment.
With this one, you don't have to spend hardly a dime to try it out. Shovel some dirt, sand, rocks or whatever into a tupperware bin, stick a wire in it, connect the other end to your whatever. Go and listen. You will see.
