There are many posts on this subject in the past,that would be good for anyone with interest to look at. Much of
what power cords...and line treatment units...and the power supplies of components are trying to do is supply a component with clean and stable power. As was mentioned
in one of these posts...RF and other airborne electronic
noise...as well as electrical appliances, etc., in a persons
home, can have impact on a component..and very much impact
what we hear in the end result. Much of this question
lies in if a person sees a power cord as a "component", as
much as the interconnects and speaker wire in there system,
or not.... A power cord in and of itself will not have a
sound of it's own, as in interconnects or speaker wire...it
is simply trying to help supply more noise free AC to the
component it is attached to. Perhaps in the fuel analogy,
it is much like Porsche and Yugo not accepting that the
fuel they are about to use is as clean as it should be...and
they use a fuel line filter...to help the situation. In the
end result what a person can or cannot hear is O.K. Unless
they are uncomfortable with someone hearing or seeing things
differently than them.... As a final, I have had good results with power cords from Wireworld and Nordost.
