There is a lot you can do.

Many of my tweaks relate to DIY equipment, but there are still things you can do that do not require equipment construction or modification.

In addition to Power Wraps on your power cords, you can wrap them near the ends with carbon fiber cloth. Power Wraps couple to magnetic fields from peak current nodes, while carbon fiber couples to electric fields from peak voltage nodes. These nodes appear at regularly-spaced intervals along the cord. The fundamental nodes will have a current peak at the center and voltage peaks at the ends, so you should start with a Power Wrap at the center.

Carbon fiber cloth sleeving is inexpensive. It is sold for people who make their own golf club shafts, race car bodies, etc., by Soller Composites:

Be careful with it, as it conducts electricity. Do not let the loose fibers come into contact with the hot blade of the plug. What I use is a size that fits over the plug. I wrap it tightly with Teflon thread-seal tape to contain the fibers and hold it closely to the power cord. This way, it can be removed without damaging the power cord for possible resale.

Your house is likely full of appliances that make RF noise all the time. Anything that uses a microcomputer to control it has a switching power supply to run the microcomputer, and both of these are on and waiting for you to push a button. Surge protection power strips that contain EMI/RFI filters can reduce the amount of RF noise that gets back on to the power wiring.

Plug-in filters such as Quiet Lines can help damp the RF standing waves on your house wiring. You have to experiment with which outlets show the most benefit from these things.

Finally, your audio cables may support RF ringing. Some cables, such as MIT and Transparent, have filters built in to them. These cause audible tonal balance problems, in my experience. The Skywire Audio cables have magnetic RF suppression technology similar to Power Wraps (Don Palmer designed them, and he formerly made cables under the Highwire name and designed Power Wraps):

I've heard Don's system, and it is the quietest and most realistic system I've ever heard.

Thanks. Will also try RC network. - amdan 23:56:44 01/10/08 (0)
