Ferrite cores on cables

Ferrite cores on cables

Why?

They do make a difference and your results rule vary based upon the location You place them. Trial and air is the key.

I believe it helps your fuel economy. No seriously, I had a neighbor who was sure and was going to rich!

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

I have tried them and never heard a difference.

Theoretically I agree with goofyfoot.  I would never use them.

Practically I agree with mike-in-nc.   

Both of these reasons point to not using them in my opinion.

Years ago tried some a different yes things "seemed" quieter but also some high frequencies went missing.

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. 

Great for flatting sound and killing dynamics and depth.

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

Only ever tried them on PC and made no difference at all.
