"golden" plate...I am very proud because it is my idea....No other product exist I know of that is like that for ratio S.Q. and price...You can look at "my systems" where I had some photos...And dont think a minute because of the look that my system sound like trash... : )
buy some shungite plate 250 gram for 10 dollars from Russia (ebay)
buy some copper adhesive tape 10mm for few bucks from alieexpress
Tape the copper on one side of the tile
That’s the big "golden" plate
For the small version buy cell phone shungite small plate (few bucks)
same copper tape on one side only...
The big plate is for your breaker central panel ( I have 5 of them there)
The small plate are for any connectors, unused duplex plug on the wall, or any unused plug on your power conditioner, or on top of your Shumann generator near the power plug, or on top of any power supply... Router-modem, computer power external bank where your music are, etc, use your imagination...
ALWAYS put the shungite side on the active face of the location, and the copper side on the exterior...
Every added piece add a cumulative positive effect with no end in sight for me.... It is audible immediately...
Enjoy a miracle at low cost and I will be pleased to read your report... I am more glad to give you the idea than I will be to sell you that, but it works and I mean my words... My best...
Like already said, I had many more tweaks but ALL homemade , tailored for my room and gear by the ears...Then always positive in their cumulative effect....
