Ferrite cores on cables

Hi , 

 I have seen a few sets of speaker cables that use ferrite cores on both ends . I do use these on my power cords with good results . Have any of you tried these on your speaker cables ? IF so what results if any ? Thanks in advance . 

Happy listening , 



I have issues with my system picking up local RF frequencies. The addition of ferrite cores on all my cables has removed the interference. For me they were a major improvement in my system. 

I also think ferite tips are evil on speaker cables.  But here on power cables, it's good.

I have never tried a ferrite core that didn't sound better OFF the cable.

Ferrite cores will strip away frequencies that are intended to be heard. 

Agreed. To my ears at least.
