ground control devices

@sksos

To confirm I understand correctly; the grounding box is connected to a component (DAC, amp, whatever) via grounding post, or other grounding (single wire).

The grounding box is NOT plugged into the mains - i.e. it is a passive device.
The component (DAC, amp, whatever) still uses a regular 3 prong AC cable meaning the component is still connect to the mains ground.

Question; have you ever used the device and while the ground from the mains is disconnected from all your components? 

The reason I am asking is I use batteries and have no mains ground. When I connect to mains ground, I pick up noise. For safety reasons, I’d like to have mains ground connected. I’m wondering if a grounding box would allow me a connection to mains ground w/o the additional noise.
Thanks.

Anyone have experience with the Puritan grounding box?

@pauly yes the wires are connected FROM the grounding box to each component. Each component is still plugged into an outlet but the grounding box is a passive device and does not require AC to operate. 
I could not tell you if using the SGS while your own components are connected to the AC outlets if it will eliminate your noise issues. There's only one way to find out and that is to try. Where are you located?

I'm on the east coast however I am not (yet) interested in trying a grounding device. I am in the middle of a number of upgrades so my ability to discern the contribution from a specific product is probably close to zero. 

I am interested in how these devices work and how they are to be used,  as I believe it's worth pursuing once my ears adjusts to my "new normal".
