Ozzy, I have my speaker clarifiers on the binding posts. Once I was listening and something wasn't right. I found that one of the speaker clarifiers had fallen off and was on the floor. I put it back on and after about 30 minutes everything returned to normal.
These cancel EMI/RFI not just in the cables, but also in the immediate vicinity of the clarifiers. EMI/RFI is very likely not a constant, so it may be that on a good day, you can remove them and not hear a difference, but on a bad day, you wish you had them back.
I tend to hang on to stuff once I am convinced it makes a difference, until and unless I find something else that addresses the same need better or cheaper.
