That's a great tip, Larry. Would you mind detailing how these ferrite
rings
are installed?


With the controls of the system set for normal listening, stop the CD,
tape or whatever. Turn up the volume control about 5 or 10 db and
listen carefully. If you don't hear any stray signals, as they say,
"Don't fix it if it ain't broke." If you do hear a bit of a local
brodcast station or ???, try the ferrite beads.



Yup....no point in fixing what ain't there! However, long speaker cable
runs *are* prone to picking up signals and sometimes those signals may
be short lived (a passing car transmitting etc.) As the ferrite
'filters' are fitted close to the respective equipment and not in the
wall I would suggest you run the cables and try it. Then if you are
getting problems you know how to fix it.
