When TDK and others first offered ferrite filters,as a way of cleaning up myriad types of interference and grunge, the support from the audio community was instantaneous. Clip a ferrite filter over your signal leads and, just-like-that, you have a clean up which is as impressive as a full Kontak session. Best of all, the ferrite 'sleeves' are cheap'n'cheerful, a doddle to fit and won't interfere with anything in your system, including other tweaks.
