Thanks for the feedback guys. For the record, yes, I'm simply looking to use a shorter cable than the one supplied by the manufacturer. I like the idea of adding a snap-on if I notice any noise. Personally, I doubt I'll have much though. Our power is faily clean here in SoCal and I've just finished running a dedicated 20-amp, 12 ga. line to where I'm mounting the TV. The AC line is running through a Leviton surge suppression outlet and then through a MC surge/filter block.
I'm wondering if the Ferrite core on the stock cable can be removed and added to the 3' cable.
That all said, we ARE talking about AC power here and a Plasma uses a bit of it. So should I go with the $1.25 cord from Monoprice which is only 18ga. or opt for the $14 cable with 14 ga. wire?
