Do you connect to the negative of the router input with the ground box? I already covered this back in 2022. I made an adapter from a 2.1mm DC plug, 2.1 chassis socket and heat shrink to provide a wire for a croc clip from the grounding box to the router -ve terminal.  My DIY skills and electricity make me wary of making one Is there a thing we could buy ? |

My router has spare ethernet outlets I use this to go to the grounding box via an ethernet cable that is cut off at one end. I might not be talking about the right connection

I might not be talking about the right connection Is it a cat 8 cable you use and connect the screen to the ground box? This is what I would assume would work to carry the ground from the router if it has metal rj45 sockets. |

Beware that router RJ45 sockets are likely to be transformer isolated. The only way to ensure grounding a router is via the DC power -ve terminal.

I have always done it this way, including the last time you visited. I just forgot to do it on a separate box.
It is not adding any noise in my system that I can tell

It is not adding any noise in my system that I can tell That's not what I'm saying, John. I just think that with many routers, with their plastic cases and transformer isolated RJ45 sockets, the only guaranteed way of connecting to the PCB ground plane is via the -ve power terminal. |

I think lowering the noise floor is important on a transparent digital based system, it helps makes the music flow, improve detail retrieval, increased impact and dynamic swings.
I don't have a dedicated space to go the extra mile like Martin and Tony.
I am getting linear power supplies for the laptop so not too add more mains noise. The trouble with Headphones is that this becomes more critical, due to the near field listening. I have also added grounding boxes to the earth mains.
I can only go so far with this approach.But I am not in a position to change it.

Are you not using a Sapphire cable, Mike? They use metal plugs.

eBay, I guess. You want a 4mm plug-in large croc clip (if you use the same QA/AliExpress cables as I do). www.ebay.co.uk/itm/363822973904May be a bit large! |

Yes, my croc clips only just open wide enough for them. |

Yes, my croc clips only just open wide enough for them. Doable but very awkward, especially when operating blind at the back of the box |

I just made a mini ground box for my router after the inspiration here.
I used a copper lug with a 4mm hole. I drilled the hole to 5.5mm and made sure it was a tight fit over the barrel of the DC plug. Applied mad scientist graphene too.
Works really well, definitely quieter streaming .

I have moved the debate on router grounding to this thread.

I'm withdrawing any recommendation for sorbothane. I've finally clocked that whenever I use an old sorbothane puck to support a cable it introduces a shouty glare to the music. Today I removed three that I installed a couple of days ago and that shoutiness has gone.
Black Ravioli never does this.
Sorbothane is going the way of spikes for me: banished!

On the router topic I use a usb port to the grounding box and that works well. Although I know not all routers have usb ports.
I am using one of the AliExpress grounding cables recommended here, it’s usb one end and banana plug the other.
