Grounding cable gauge size

Rochelle salts are getting difficult to find lately.

I also use the 3M EMI absorbing material with the adhesive backing in my boxes, usually on the last surface away from the item being "absorbed".

After looking over the Entreq site recently there now stating the grounding box should match the component it’s grounding ie. weight the bigger the component the bigger the grounding box needed along with another thread I read where the box has one cable inside the box or compartment some of the larger Entreq box have multiple compartments thus multiple cables. 

Entreq now list the mixture , tungsten , magnesium, silver etc. so I did the same. I’m sure my mixture is different but it still made a huge difference in the music. 
 

It’s like any tweek really “ you need to read , experiment and try different combinations to reach the desired effect your looking for.

They do work .

Have a Signal Ground Solution SG1 grounding box from Andrew in Scotland.

Have two of his copper grounding cables, reasonably priced.

Waiting on a Silent Point grounding box I've ordered.

Could someone who has a grounding box take a voltage measurement between one of the ground terminals on their grounding box and the “D” shaped hole in their wall outlet?  I’m curious if a voltage differential exists.  I imagine it will be in the microVolt range if at all.  The D shaped hole in the wall plug should go to the earth ground outside of your home so virtually no risk plus a voltmeter has a high resistance across the leads.  Put the red lead in the D hole and the black lead on the grounding box terminal.  I would expect a positive voltage reading if anything.  

I also added a outlet on the grounding box that grounds dac and server , using a 14 g pure silver wire attached to furutech ncf plugs into the house outlet like Entreq does and it certainly adds a more 3D space.
