Are ferrites effective for cabling?

Bingo! And Bingo, again! 🤗

You know that random approach to trying things without knowing what they do is only going to cause you frustration. People who design electronics don’t just say “hmmm, that random handful of parts looks good to me, they will do anything I want if I believe it enough”. Failure to plan is the same as planning to fail.

I reseached the right ones to use and experimented. Did my due diligence. Dulled the sound unfortunately. So yes one could say they lowered the noise floor, but they also lowered the Fidelity! Oh well. 

Exactly! And it seems like such a good idea, too. File it along with other things that don’t work, like lead, Sonex, ERS cloth and keep moving. A rolling pebble gathers no moss.
