Abe, see my response to your comments over in the Dunlavy thread. What you and i were taught in school is "theory", not "reality set in stone". Obviously those theories do have some validity, otherwise we wouldn't be where we are today with the level of electronics that we do have. Nonetheless, we know a lot less than what we think we do about a LOT of things. When we stop learning as a individuals, we're doomed as a race.
As an electronics tech that has worked as a design consultant for over half a dozen manufacturers, i used to have a similar point of view as you. Then i actually tested some cords and found that "common sense" need not apply to everything that happens with electricity.
If you think that the power coming into your house is "clean", better break out your scope and do some measurements. Just as a filter can be built from electronic components, why couldn't this be done with a power cord ??? By manipulating the inductance, capacitance, etc... through the use of specific materials, geometries, shielding, components such as caps, etc.. this is completely possible and is done on a daily basis. Think about it.
As to the cost of such devices, i agree that they are quite exhorbitant in price. Then again, they are specialy items made on a limited basis in most cases. As such, show me a specialty market and i'll show you a high mark-up. Sean
