Default ART Cleanbox

I picked up one of these cheap a few months ago and never really used it much because it liked to tune in radio stations.

I opened it up and removed the ground from the chassis and amazingly it is now noise free. The ground wire now just floats. Initially I grounded it to a grounding post, however I get less noise without a ground at all. The power source for the clean box is a AC adapter(wall wart)

Any ideas? I am amazed this worked and I am curious if anyone has any theories. Is it safe to do this?
