Description

Ground Box 6”x6” (2)
-  Made of scrape melamine covered in contact paper
- Copper plates, copper tape,  banana plug, bare copper ground wire, 
   12ga stranded copper speaker wire 
-  50 g Tourmaline fine stones
-  225g raw Tourmaline stones
-  50/50 volume mix of rock salt (4 lbs) and horticulture charcoal (2qt)  Connected one box to each speaker neg posts

Large Ground Box 12”x7”x6”
- Same as above with these additions
- 2 banana plugs
- Copper color aluminum plates (work as well as the copper and easier
   to cut and shape)

@tksteingraber Yeah, it's going to be fun. But only Graphene is expensive hence very small quantity, rest all are quite cheap. Tourmaline costed less than USD 8 for 1 kg, so did others...so it's not at all expensive for me.

@audio_phool     I do have it plugged into my ground see prior post.  I chose my ingredients after researching materials.  Many of your ingredients are pricey and don’t offer much benefit over rock salt vs quartz, charcoal vs graphite.  I did add small amounts of tourmaline, Graphene but wanted more volume with charcoal and salt. My 2 cents..have fun with it.

@tksteingraber I would suggest you to connect your ground box to earth of your wall socket and leave it as it is for a day or atleast 4-5 hrs. I am not sure how these works but if it is collecting ground noise in the material mix, it is essentially accumulating the charge which it can not drain as it is as there is no other connection for it to discharge it to. Think of it as variation of a capacitor. Capcitors can only hold a certain amount of charge and they will need to be discharged through a path.

I am building my ground box using mainly quartz chips (both transperant and pink in equal quantity), black tourmaline chips (double thbe quantity of quartz), little Shungite, Pyrite, Blue Apatite, Malachite, Magnetite Powder (Iron oxide), Graphite powder & Little Graphene powder for seasoning :)..I am excited to see how this mixture turns out and how does it affect the sound in my setup.

@audio_phool  I forgot to mention that on my power conditioner box it is connected to the wall duplex outlet ground which draws noise out of the box to the house main grounding rod outside.

@audio_phool These are my understandings but I’m not a science expert:
1- Copper or Aluminum sheets attached to ground wire connection provides more surface area to draw and collect the ground noise so it can be filtered out by the charcoal, crystals, salt etc.
2- Discharge occurs naturally through absorption by the charcoal, crystals, salt etc…it is maintenance free.  Tom

Your grounding box surely looks good. I have few qustions regarding it.

1. Why have you lined up the internal of box using copper sheet? What purpose does it serve?

2. Since this grounding box is supposed to just collect the charge over the period, how do you discharge it?

Sorry and glad I could be an inspiration!

Wow!  Dude, I'm both super impressed with and super scared of you!  Because you so seem like me!  There's no way that I don't build some ground boxes...damn you and thank you!!!

Sounds like a project you need to complete and see for yourself.  Have fun with it. If it doesn’t help chock it up as a learning experiment…cheers!

of course, I read a lot on this topic ... Entreq and the like ... I haven’t heard it myself ... I guess the larger the box and the more different fillings there are, the more likely it is to get an effect ...
you need something that will eagerly suck currents out of the ground cable ...

@serjio it’s a fun experiment with a 6”x6” ground box or you can call it my “Bad Boy Matchbox”. -) When attached to the audio outlet ground and my power conditioner ground lug it provided a cleaner/quieter noise floor.  It has gotten better after several hours of use.  I attached it to my phono preamp ground lug as well and saw improvement there as well. Still work in progress…i want to try using better quality larger gauge wires to see if that has any impact. Look up ground boxes on the net…

Read “The Second Noise Floor” forum thread for more info. https://forum.audiogon.com/discussions/a-second-noise-floor

tksteingraber

well, tell us what magical effect you managed to achieve))) ... this box is not much larger than the "box of matches" - I have vague doubts about its effectiveness (but I would like to have something really working)
