Are ferrites effective for cabling?


Good day.  I have several ferrites in varying sizes.  Are they effective for eliminating noise or stray inductance/capacitance?  If so, would they be best utilized on interconnects or speaker cables, or both?  Or, should they not be used at all?  TIA for your thoughts.

I’m pretty sure you’ll find the answer is .....no. They do work quite well on non-audio related cords, though. I mean, to improve the sound, in case my statement is ambiguous. Oh, no offense to anyone who thinks they work on audio cables.
Verastarr uses a power mixture of earth minerals having noise reducing properties. Contact Mike Powell Audio to discuss. He has posted videos on his YouTube channel about these materials. His YouTube user name OCD HiFi Guy.

Best place I think is in power cables.

Worth trying on the amp side of a speaker cable, especially with amps that use feedback.
