Noise blockers or "grounding boxes" review. Magic devices for everyone :)

First thing: do not buy them, DIY them. They kinda work, but they have to be big enough.
This is "esoteric hifi" for me as I'm not sure the explanation for this makes any sense, but many people swear to it so try it, as its as simple as plastic box filled with sand and a piece of wire.
There are also companies that will sell you these for gazillions of USD.
If you have any questions, share them in the comments, I have quite a lot of my own, so we may do some trading ;)
If you're not brave enough to fill the box with sand and plant a wire in the middle you can get small ones premade f.e. from here:

If you want to do this for cheap, and better, take 7-8 AA batteries, use copper double sided tape that is conductive in both sides and connect all the + poles and - poles together. Then attach the POSITIVE terminal to your equipment ground points. Leave the negative pole unconnected OR to enhance the effect connect the negative pole to true ground at your wall. Trust me, I have the most extensive ground system around.. This plus many other things.

[@k4syx]

Thats actually interesting thing to do, and easy to try, looks safe too. I'll try that sometime in the summer! This would work better as a "sink"

[@TheDocAudioShow]

@@k4syx I think I've spent more time optimizing ground than many haha, big gains to be had. Super easy to do. To optimize ground you need a combination of ultracapitors for high frequency, larger is better I use a 3400F Eaton, I use dual kemet 150,000uf electrolytics which you need ultra low esr for sub 100hz for ripple rejection, a large 20ah lifepo4 battery 12v connecting positive pole to star ground and then Panasonic fr series capacitor 16v 47uf cap between +/- pole of the battery. I have brought my ground noise from 1400mv ac to 0.8mv ac with this setup. The sonic improvement on my already truly end game system was not small, not small at all.

Don't forget about the round little fuzzy discs! If you place them 2 CM apart on every surface in your room it greatly reduces harsh echo effects! It's true, try it for yourself!

[@barskuleli8612]

I made my own ground box. In a wooden box I put iron dust, aluminium dust, glass, ceramic, charcoal, rock salt, tourmaline and sand. I made some kind of copper pattern inside this cocktail and solder it to speaker terminals behind the box. You can connect all your equipments.

[@TheDocAudioShow]

I did this too, but you can make it so much better. The trick, see my content it shows my systems sound, run from this box some big 300+ farad ultracapitor connect + to this box and negative to true ground, then do the same with a big kemet 100,000uf or bigger hook it up the same and use kemet the best for low esr ripple for under 100hz... Those two things added to your setup now will blow you away

[@barskuleli8612]

@TheDocAudioShow I think your approach is different than mine. I think both work...

[@TheDocAudioShow]

@@barskuleli8612 no it's not, I've gone to the end of the end with my grounding system. I also used Oscilloscopes to verify and test everything, including listening. You have a lot of noise remaining on your system I guarantee it. Trust me, the caps will shunt the nosie to ground and the polarity won't allow back feed. I guarantee you are blown away with a maxwell s19 325F cap and 150,000 kemet 25v cap + to your box negative to wall ground. You will be truly blow away... You can do more than this. When you see how much better this sounds, reach out and I'll tell you how to take it farther. Guarantee

[@razisn]

You forgot to add salt 'n pepper.

[@barskuleli8612]

@razisn I added salt don't worry about it..

[@kevinchew2594]

Halo , sir ! Can show the whole process and what material to use ? Tq

[@TheDocAudioShow]

They are not sand or crystals. These are AA batteries encased in black epoxy trust me I have like 10 of them. They work but you can make your own very easily. You can see my system, I use them, they do work.

[@dirkrs]

Hi Doc, can‘t see this in your Videos? Make a Video and open one. Tell us more about your capacitors? Thanks greetings Dirk

[@TheDocAudioShow]

@@dirkrs I will make a video about my grounding before long subscribe

I came here just for the comments, lol

Ho my dear i can't stop laughing.

[@fredrikbarthel4803]

You can't use sand it has to be a piezo electric cristal, they convert electrisity to heat/vibration. They all contain a charge and from fysic's we knov that electrons want's eqiliberty (tha same way a batery discharges) but if you apply current to a ctistal it start's to vibrate like a crystal ocilator in a watch or a dac (quartz). you should try the bigger boxes they have a big impact om dac's (conect to signal ground on rca)

[@k4syx]

Yes this is easy to try - just a big box, bowl , or aything really filled with sand

[@fredrikbarthel4803]

@@k4syx Sand will not work!! It has to be a piezo electric cristal like tormaline or quartz!!! There are several U-tube clips on the prppretys of piezo electric cristal watch them. Just stop caling it sand it willl not work.

I have cut them open... AA battery in black epoxy... Lead solder to + terminal. Uses positive pole to attract negatively charged electrons

[@k4syx]

@@TheDocAudioShow So this actuallu would be different from regular grounding boxes: I think I need to cut one of mine open. Or use magnet, charged AAs should react.

[@TheDocAudioShow]

@@k4syx I PROMISE you they are AA batteries lol. I used a angle grinder cut the top off becareful because it is a battery... You will see I have pictures of me cutting them open just can't post here

[@TheDocAudioShow]

Why did you remove my comment? I cut these open. They work for sure. They are AA batteries... Using the + terminal to attract negative charged electrons...

very interresting, i will sacriffice mine and see

All you need is an RCA shorting plug. None of this BS.

[@Douglas_Blake_579]

Seriously??? Okay lets be rational ... If you hook a chain to your back bumper and leave the other end on the ground, how many cars will move when you drive away? A chain going to nothing... does nothing. Same here... a chunk of wire going noplace does nothing.

[@k4syx]

Actually stray currents induced in shielding or cases are real. same goes for internal components, though its debatable if the scale there is large enough to let you hear the change. This would work as a sink for free flow electrons BUT not the same way as grouding this as this would not close the circuit. On the physics level I buy this as I can understand the rules and this sticks to my professional knowledge. However as I said, there is just one system that I have that is transparent enough to have any effect. If youll read comments below one of the guys says these are AA batteries with + connected, that would be even better as a sink. You can try this for like 1 usd on your setup.
