Grounding boxes are not just for digital sources.

And in answer to the question of the boxes filled with enigmatic material, it's taking the the signal ground to a (hopefully) lower impedance point. The signal ground is for analogue signal. The box provides a passive drain for RFI.

Could this work with a phono stage or are we just talking digital signals? Yes. |

I would be very interested in what is the best 'enigmatic material' in use by these grounding box vendors.

Shunyata bollocks or summat, according to Fluxed  |

Well the Vampire poo looks like it could be specular hematite, which is an inert form of iron oxide, and is often used for shot blasting because it's very tough and it doesn't rust.

Chris Only if you have some rough odd bits of material to clean up, like rusty/oxidized car parts or some long lost treasure found on some distance land. Personally I prefer vapor / bead blasting much more effective for delicate and intricate shapes and forms. Which why I have a blasting cabinet of the water/avpor variety Great if you wish to remove the crusty bits from Shirley Basses underwear though I've be informed. |

Could this work with a phono stage or are we just talking digital signals? What's the phono stage? If it's valve based I'd expect it to already have some kind of ground reference.
Yes I've got a tube phono, was just wondering if this box can do anything with analogue ... worth trying with amps I guess. |

You might hear something, although you'll already have a ground reference point held above the chassis ground by a resistor. You'd need to try it. You might not hear any difference at all.

If only you knew. Early start this morning. Essential bike ride as it may be raining for the next few days, without me on a bike. Back for lunch. Problem with a dog - down to the vet. He's now sleeping so hopefully mending. Photos needed of speaker cables first as people think I have to show both of the pairs. - Can see their point. Going to use the boss's phone as that seems the best camera currently in the house A picture is worth a 1000 words so I'd better get on. |

It seems like the only way to go is to do a lot of testing. Sadly I’m not a person who like to test an do a lot of comparisons. But something tells me that signal grounding is one important step in the chain to clean the digital signal. Exactly. I read up on grounding boxes and there is no consensus on generic advice for using them. I have been experimenting and am on about the fifth set of connections. Now I'm listening more which seems to indicate I've found a sweet spot. It may be different for different grounding boxes! Please do add your findings when you receive your SGS, Zacke. I will be very interested. Yes, I will tell you my impressions. I have five types of cables coming with the SGS. So there will be a lot of combinations to try. I have read advices that are very far from each other. So it’s really confusing. |

I have two cables. I'm using the spade-to-spade from SGS to DAC ground post. The banana-to-crocodile clip cable goes from SGS to preamp power supply. I'm still listening and may try a further change or two.
