Preliminary DIY Grounding Box Result

I live in a big, downtown high rise building. Our grounding is crap. I just took a 12 awg sliver stranded wire and stripped both ends. One end went straight into the center of a 3 pound bag of magnetite, and the other stripped end was wrapped around a spare coax rca input (outside negative) on my DAC.

Result: Highly noticeable "analogue-ing" of the sound, along with more dramatically more pronounced soundstaging. Space between the instruments seems like it tripled. Smoother, detailed highs and warmer, dynamic vocals.

I have some quartz coming and will mix it in. Plus I’ll run to other components and report back. Just wanted to try this for a quick test.
More Flat Earth Science! Only a true earth ground (copper rod driven into the soil outside) has ANY benefit! That is how lightning protection works (by shunting the HV charge to the path of least resistance). Next best is connecting grounds to a cold water pipe - as long as it is an all-metal pipe running to the main water source.
A pail of magnetite is not a ground! And a bucket of quartzite is equally useless! Use the cold water pipe if you want to experiment and don’t have access to the outside. And again it must be all-metal piping from basement water source!

Interesting. If you say it improves the sound quality keep at it. I own a SR grounding block, wonder what is inside it ?

SR grounding block (another fine product from the genius mind of T.D.) - as effective as a copper bracelet for relief of arthritis!
My guess is that the perceived benefit is the result of the wire + magnetite that is connected to the DAC’s circuit ground acting as an antenna, and introducing RF energy that it picks up onto the DAC’s circuit ground. Resulting in some combination of intermodulation effects, jitter effects, and/or low level high frequency noise effects which happen to be euphonic.

The fact that this is in a "downtown high rise building," which is no doubt replete with numerous sources of RF energy, would seem to add credence to that hypothesis.

Plus I’ll run to other components and report back.

Doing this with multiple components (connected to the same bag of magnetite) **might** result in ground loop issues, causing hum and/or low level high frequency buzz.

Oh geez, here we go again! Audiophiles love 💕 noise and distortion. Yeah, right! The fact that roberjerman agrees with him makes it even funnier. 🤗
@geoffkait: Rumor has it that you have a working example of the Dean Drive? Inertia-less force is ready to be unveiled!

I just hooked up the SR grounding block to 4 of my main components. I also added a Akiko rca tuning stick to the ground input to the SR.

There is a definite increase in image specificity. More grounded (pun intended). I don’t know why, but it is noticeable.

OK, I just decided to "Play" with this concept. Anyone one have an idea of the (best?), mineral mix and the percentage by mass to be used? Other than Quartz, Tourmaline, Magnetite and Iron Ferrite granules?

It sounds like they all need to have similar properties. In that each component is reactive in some way to an areas "specific", magnetic field. Kind of like your making, just dirt. Yet a dirt/soil without the non-reactive components. "Dirt on steroids"! Placed inside a sealed, solid wood paneled box. With a minimum interior size of one square foot. Then an audio,- RCA, IEC, or other similar connector bonded to either copper coil/s or Copper/silver foil as the electrode. The electrode then terminating in the center of the strata of medium used.
   Hee hee hee, am I missing anything else here, besides my mind?
 And If I "then", placed the box near a dedicated ground buss and bonded it to the....

 But seriously, I have everything here except for "all", of the minerals already. So I shall attempt this. Off to the hardware store for dirt components!
Tomask6? How did the quartz work out for you? I have picked out eleven different mineral elements. Each chosen for it's properties in relation to a, "Possible", interaction with the surrounding area's ambient and, "static", fields of charge. I have several varieties of quartz now. Sized into different mediums. Tourmaline also.
 According to this very nice gypsy lady I met this week...
Quote; Pink Tourmaline is a crown chakra stone, and Blue Tourmaline is a throat and third eye chakra stone. Black Tourmaline is an effective blocker of negative vibrations and psychic attacks. It’s a highly protective stone that will pick up on any disharmony in your environment. It will transform this disharmony into peace and serenity.
    Ha ha ha ha, not real sure that I'll incorporate any of, "That", into what I am attempting to do here. This is all just a.shot in the dark right now to me. "Right now". But too many people are hearing a difference to discount it completely.  I was looking at a, "Nordost", ground box earlier. Those have an aluminum case.
 I built two from Rock Maple, 10" x 16" x 9" deep. One I shielded and damped in several layers just to see if any isolation will make a difference. "I'll measure everything against my baseline  Which is a rig in the next room. The second box is I lined with some 3/4" Red Cedar only. That should help with any critters piggybacking in on my synthetic dirt! And give me another box to measure against the first one. The wire topology will be the same in both.  As a control.
Does anyone here, "have" some type of this "Ground box" as they call it, device already? And maybe willing to share their experiences with it?  And if so Have you/they ever tried to see a difference not in sound. But say, In the resistance across the end leads of the wire. Before any wire enters the box. And then across the leads from the connection at the ground box itself entering it. and again where it exits the box? Or maybe looking at the information moving through the wire, "Again in the same two exact area's". With a scope, Oscilloscope or other instrument of measurement. Along with maybe a tone generator?
OR any other type of measurement, reading ect.? Which may be of help?
 I have a plethora of equipment at my disposal and will measure, test and read myself. But I was just wondering if someone has any info that could save me some, headaches/dead-ends etc??
Ok, Both "boxes" are now insulated, damped, double/ triple shielded.   
With all sides bonded including the top.
Shielding is achieved with aluminum and copper foils bonded with copper wire. Electrodes will be 1/4" thick, 2 x 6" pure copper bus bars. Which will be held aloft into the center of the mineral mediums by ceramic insulators 3" tall inside each box. Bus bar bonded back to the outside of the case with WBT copper binding posts. Mech. welds are used for all bonds. 12awg silver plated copper used for all wiring.

All minerals listed on the earlier posts soon to be added to the interiors with the addition of a mineral named, "Shungite", a known source of "Fullerenes". The known natural construct with the property of superconductivity. Which fits in nicely with the other minerals and their own odd, "Stasis charge" qualities of a very positive photonic nature.

I plan to induce a polarity with niobium magnets. We'll see!

Can anyone else see the virtual construct this seems to be leading itself into? A copy of something much larger. With "Hyperreactive" strata condensed into a very small package.
There is a "Box" from England that has a circuit which "fools" shortwave radio EQ into working as grounded when in fact there  is "No" actual ground. Developed for enhancing the signal quality available to people relegated in that hobby to "Odd" set-up area's. There are a few video's on "Youtube" about it with this, "Circuit". They linked an address as well for a schematic of the circuit. "Which I downloaded but have yet to really investigate asn to what that circuit should actually do". I have now looked "Inside", a couple of different "Grounding boxes". They have had basically the same interior set-up with a foil or thicker metal, "V" inside.  Some had metal plates behind the "V". Some had several of the plates. One had two copper rods behind that, "V".
  One had what I believe is a "Capacitor bank" as well inside. but at the time I did not have anything on me to test it with. These were the size of "Soup cans". And with the leads set-up the same as the average catalytic cap you see in most amps.
One used a foil made from silver as the "V". The rest were Cu.
One ,"V" was even a "Grounding Bus Bar" that looked like it had been placed into a vise at the half-way point and then, "Beaten" with a maul until the, "V" shape they apparently wanted was achieved!  
  All had varied amounts of a black mineral. Some had the mineral in plastic bags. Some were simply loose inside the boxes interior filling it.
And that is where I am currently at. 
In shortwave radio and broadcast AM radio, part of the signal travels thru Planet Earth. So a stake in the garden acts as part of the antenna. When a path to Planet Earth is not accessible, a 'counterpoise' is sometimes used. It would be an arrangement of wires or metal objects to act like Earth.
An all metal water pipe system is a much better 'ground' than a stake in the garden. But many cities are replacing metal with plastic, same goes for inside homes.

You’re more than a little bit confused. A stake in your garden isn’t going to improve your AM radio reception. A radio station ground plane is part of its antenna system, but the signal doesn’t travel through "Planet Earth" on its way to you.

And oddly, a radio station ground plane isn’t even necessarily connected to ground itself.
I am wondering to built a gounding box for my system. Please can you tell me what kind and quantity i will make the mixing minerals stones it will be the better choice. 
That answer? 
 That would be exactly, (Half) of the battle won, my friend.
I have accumulated some strata try. I just have not the time at the moment.
So, how goes these experiments?  Does anyone have pictures of these grounding boxes?  And what minerals have done what?
Honestly, the project is currently sidetracked. I "know" that we currently do not understand particle field mechanics OR even grounding enough to understand more than a tiny bit of "why" these work. "IF they even do"!
After seeing the interior of a few different types of "working" boxes from other manufacturers?....:Which REALLY gave me quite a (pause)"!
 I "have" been mulling things about in the back of my mind though.
Soon enough, Even "if" I cannot find or figure anything else about this?
I will attempt some "Trial and error" configurations.
   As time has permitted, I have been slowly working up to that anyway. "And have also been purchasing some new measurement gear".
A LOT of new gear actually....
Who knew a microscope with a new, "Thermal Imaging" tech. would make such a great toy!
I did think that I might get more information than I have from others here and elsewhere. But that has all led to dead-ends.
For me in my system I found three and even better four 18 g stranded silver wire sounds best , 2 is minimum even mixing a couple of 18 g with several 24 g sounds great just use more then one Entreq uses a few in each ground wire .
So, "Tecknik", You mean they use a percentage of silver from the (box) to where you are introducing that piece of gear into your homes grounding system correct? Like at the receptacle. Or are you going to the panel? Or to the grounding electrode outside itself? "Bypassing the panel and there bye intentionally causing a ground loop"? Or other?
 I am asking because it "is" that one tiny detail that can make something work at times.
 "Nikola Tesla" insisted at his last workshop on having the power demarcation location placed, "exactly" above an underground stream. "Which is how he decided on not only the property. But also the location and orientation of that building". Then they had to dig down to it and place the grounding electrode into it's center. And only then did they drive it into the ground. "Leaving the top (12") of the, (10') electrode and also the ground wire from the MDP. "In the streams flow".
(He made several mentions of the importance of this in his notebook).  Damn, I don't remember what metallurgy or gauge of cable he specified for the main bonding conductor! But I do remember that It was welded to the copper rod with a gunpowder ignition"! (No split-bolts)!
 I am not to sure that the use of Ag here would cause any greater benefit than the use of simply a larger gauge cable though.
But then.....none of this should work anyway!
 "Per the NEC'! Hee hee

High end audio  always had a grey area about defying science with these special cable,boxes,and solutions but this grounding box and the price is insane.
