Did you read my explanation on ferrite forming an inductor like the article showed in the graph? At higher frequency, the impedance goes up and break the ground. For single turn inductor like in torroid I suggested, the impedance doesn't come down until very high frequency as capacitance is very low.
Like I said, using ferrite is a standard way in reducing noise......reducing ground loop whether you buy it or not. You don't like, don't use ferrite, this is a standard way every EE use as the first line defense in noise reduction.
And yes, most of the noise like this are caused by ground loop.
