Noise with Computers, USB DACs, and Powerline Ethernet Kits

[Paul Birkeland]

Yes, I have two local customers here who have sub panels with neutrals bonded to the sub panel. I have spent a few years trying to convince both of them to put in isolated neutral bars, but both just say "some equipment just doesn't work in my room".

You definitely get the gold star for having your wiring checked out!

Would it be advisable to just do this mod during the initial build? I just ordered my Crack.

 

[Paul Birkeland]

That is certainly an option. If you don't plan to use the Crack with a USB powered source, you may not need it at all.

Hey all, not sure if this is the same issue as described.
I use a Schiit Modi Multibit 2, and when I turn on my amp I hear a whiring electrical noise. If I touch the amp chassis, or screws the noise will drop. After a little bit of doing that the noise is gone.

What's going on exactly?

 

[Paul Birkeland]

If touching the chassis changes the noise, then you may have an actual grounding issue with your kit or with your home's wiring. In terms of kit issues, this could be things like having the bottom side of the chassis painted/powder coated, loose hardware, or improperly installed hardware.

For home electrical, if you do not have earthed mains, then you can get strange behavior like this.
