I purchased some powerful Neodymium Rare Earth Rod Magnets about 3/8" diameter and 1" long that are axially magnetized, Poles On Flat Face. They sell for about $4 each). I placed two of these per speaker cable at the end near the speaker spades. With the opposite pols pulling towards each other through the wire. They grab like hell and will stay in that position.
There is an improvement in sound quality. I wonder if this is what Virtual Dynamics was doing?
For those experimenting with magnets, some other interesting places to try them is on power cord plugs, any steel or aluminum case of electronics, on wood bookcases and other wood furniture.
My best option was placing three, on the back side of my amp's transformer. The magnets don't "stick," as much as they just stay in place. They are from Monster Magnets, www.magnetsource.com They are circular, with a hole, measuring .74 in od x .375 in id x .105 in thk. These were the biggest ones in stock at a local electronics store, $15.99 for three. In my opinion, equal to or better than a cable or power cord upgrade!
