iDefender - defeating static noise?

[NancyJohnson]

I'm curious whether anyone has (and has had any success) using an iFi iDefender between a PC and an audio interface to reduce monitor noise?

 

Ever since I switched from an old Dell PC to my HP I've experienced a quiet static noise/interference through my monitors...my setup is PC > Focusrite Scarlett 2i2 > M-Audio BX5s.  It doesn't matter what setting the interface is on, the background static/noise is always there.  I also get a little bit of noise if I'm using the scroll wheel on the mouse.  Nothing comes through on recordings, it's just blumming irritating.

Is your computer a laptop with a class 2 (double insulated and no earth) PSU?

 

It may be missing a ground connection somewhere in your set up.

HP Desktop... honestly couldn't tell you what processor or specs.

 

It's an omnipresent low volumed hiss/static/crackle, not a (traditional sounding) ground hum. It doesn't matter how high the output is on the interface or how high the volume us on the monitors, it's always there.

Can you check the PSUs for the interface and powered monitors?

 

Do any of them have a plastic earth "connection" on the plug?

@NancyJohnson If your PC has USB 2 and USB 3 ports you could try swapping from one to the other if you haven’t already. I  suspect the power supplies may be derived from different points in the main psu as they have different current capabilities. You may just get lucky .
