So per the website https://www.entreq.com/products/ground-boxes-17667704 it supposes to lower the noise floor since the home electrical system is full of interference. |
well it can be expensive snake oil - https://www.thecableco.com/accessories/grounding-devices/olympus-tellus.html $9,260 USD |
here is an example https://www.youtube.com/watch?v=NOVfFLTXB3k do a search for audiophile grounding box or wood grounding box to find more. |
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? |
invalid, 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? 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. |
Ok besides the off-color comments.... 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? Thank you for your comments. Bill |
