This is probably more of a tvi reflector question... is there one of
those, or is this place good enough???

I get into my new dvd 5.1 speaker system.  I picked up some shielded
speaker wire and ferrites.  But what is the 'correct' way to implement
them?  Obviously at the speaker end of the wires there is no place to
ground the shield so that will have to float.  Or is there something
else I should do with it??  At the receiver end I can tie all the
shields together and to the ground there.  What about the ferrites?
Would you put one at the speaker end?  Just with the 2 speaker wires
through it or with the shield also??  And on the receiver end, put the
ferrites on just the 2 speaker wires between where the shields are tied
to ground and the receiver, or before tying the shields together??
