So I purchased these speakers for my wife's office space. Upon initial setup in our house everything seemed fine, but upon setup in her office space she was getting some kind of mysterious background noise (even with no audio source connected). Further investigation proved it to be radio signal from a local station coming through the speakers (both while on with no audio source and in the background during audio playback). A little consultation with Dr. Google, it seems the internal grounding in these in none too good.
Solution: Ferrite core noise filters on the power strip, the primary power cable, both speaker cables, and a new Fospower 3.5mm to RCA input cable. Now no background noise.

PixelFruitloopsI'm not sure how much more I can explain. If you go on amazon and search for " Ferrite core noise filters" you will have a ton of options, almost all will suffice. get a pack with multiple sizes. The filters just snap around the cables. Start at the wall outlet and place a filter after every time the electricity's path encounters a new component (powerstrip, speaker amp, ect.) Once every cord with voltage has a filter, you're done. I also just upgraded the 3.5mm to split RCA cable to a Fospower cord. It has better shielding and just is an overall higher quality cord. I may upgrade it again to an Audioquest cable.
