I am a HUGE fan of ferrite clamp-on inductors...

Just not on any of my audio gear.

I have them all over my home, on any AC cord that might connect to an appliance or light that could feed noise back into the AC wiring... appliances such as the fridge, microwave, washer, dryer, TVs, DVD players fans, garage door opener... anyplace anything with a SMPS might be plugged in including computers, phone chargers, networking equipment, non-incandescent lights, etc.

I also have a bunch of parallel filters plugged into various outlets near noise-sources, mostly QuietLines but a few MIT ones too.

The ONLY place where I find clamp-on ferrites to be useful in the stereo is on the power line to or power feed from computer-related audio gear in the system. So on any computer player, NAA, server, or networking gear such as routers or wireless access points. Even ethernet cables get these clamps.

I was surprised at the difference putting clamp-on and parallel noise filters made in my system, even when I have local parallel filters on the AC lines to the equipment AND most everything directly involved in producing the audio signals are run through PS Audio P10 AC Regenerators!

YMMV!

P.S. I have tried them on audio AC cables and interconnects at various times... NEVER found them positive there.

Everything matters!
