Dear Bwhite,
We make a shielded power cord that is very effective and quite affordable. Take a look in the Misc Audio forum and see what one of our customers have to say about our PC/REL Sub combo. We regularly have one up for auction. Should you need something different or have any questions, contact me directly. Visit our web site at dedicatedaudio.net for more info. Hope to hear from you!

Before purchasing a shielded power cord you must consider the sources of interference. If the cable run along a wall you must determine if any household wiring is located within the wall since it will have the same effect as using an unshielded cable. Household wiring located below the floor will also be an interference source and should be considered when locating the equipment. If possible you might consider getting the listening area rewired with shielded cable to eliminate any potential problems ( this will be much more effective than just using shielded power cords)

Dear BWhite,
Not to step on any toes and not to try and make a sale, I don't feel rewiring is a wise move. Be sure to check your local building codes prior to rewiring the listening room. You could be placing your homeowners policy in question. Shielded power cords are VERY effective (be it ours or someone elses).
Go to HD and purchase a GB Instruments Circuit Alert($15). It is about the size of a highlighting marker only red in color. It is in the electrical isle. Depress the button and scan the area in question. If it beeps (as it will next to unshielded pc's) you have stray AC voltage which can cause problems with IC's and speaker cables. It's also a cost effective way of checking shielded PC's at your local high end shop. It's one of those kool little tools to help us justify our spending to the better half and show off our PC's effectiveness to friends.
Hope this helps!
Happy listening,
