Ferrite beads/clamps as a tweak?


I've been reading that ferrite clamps can reduce RFI/noise on just about any cable - power cord, video RF cable, IC, etc.
Can they also hurt the sound? Why wouldn't you want these things on every IC, power cord, video cable, and so on - even household appliance cords like the fridge etc? Do they reduce RFI leaving the appliance or just entering the device?

It seems like putting these things all over the house would do a great deal to reduce noise. I don't have any specific interference problem except with cable and FM reception. Seems like an obvious idea for cheap system tweak.

on AC cords no perceived problems here...
on unbalanced interconnects; HF attenuation was an issue using Audioquest RF Stoppers
