Hello everyone!
 
 I am currently having issue with a buzzing noise I get from low frequency’s 10-50 hz I have and had the magni and modi plugged into all of the usb ports on my computer tower and I thought I narrowed it down to the dac but then unfortunately only to try and use the stack on my Microsoft surface and the buzz was no longer present

. So it must be my usb ports in my MOBO?
                Does anyone have any idea what may cause this?
 Yes I have switched out my cables and other methods of interference.   
 
 
Starting at 10 hz the buzzing will happen
 
here is a website i use.

Thank you

The surface is a battery-powered device, and the battery isolates the surface from any ground-loop issues involving the AC power. Just to check to see if it a ground loop, you could try putting a 3 prong->2 prong adapter on the power cords of the Modi & Magni. The adapters cost less than $1 at home depot. I don't know if it's a ground loop, but it's a cheap fix if it is.
