BEST AC CORD UNDER 1000?

It's like trying to explain to someone how the same gas with
the same octane can cause different results in a Porsche
vs. a Yugo.... Perhaps as one builder/craftsman can build
a great house out of the same raw materials...and another
can produce something that will be torn down in twenty years
or less. A raw material is just that....what a person or
device does with it may or may not produce excellence.

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.

All wire, all metal, can act as an antenna to RF...all antenna are metal arranged in a manner to receive a bandwidth that the designer had in mind. In that same vein,
wire can be designed in a manner to reject/cancel unwanted
frequencies. The less RF and other noise introduced to
an audio components power supply or chassis give that
component an easier time in doing it's job. As in waveguide
theory....quater-wave away from an open, is a short. A powercord design can do a good or poor job at being a short
to RF...ie: an antenna..or an open/choke/block. What we're
trying to work on here isn't 110v 60cps. You'll have to
look to higher level HZ., or your own ears. But again, if
there is nothing heard in an upgrade powercord, then it
isn't worth ones money.
