Powercords

Noise is either the byproduct of a poor electrical signal in, a case of poor product design, or improper installation.

In the case of a poor electrical signal...that depends on what side of the supply box it's on....if it's the line coming in from the power company, you have every right to have them correct it. If it's on your end, then you have a home wiring issue that needs resolved.

In the case of poor equipment...either RMA it until they fix the problem, or stop buying their products. There are many "audiophile" brands out there which have disturbingly simple power stages. Simple does not equal better, proper noise filtration is a must.

In event of improper installation, remedy the issue that lead to the symptom....case closed.

All a cord with built in filters and such will do is correct for defects elsewhere....a band-aid fix. It's far better to remove the defect altogether, from an audibile, and financial standpoint.

It is amazing to find so many posts doubting that
a power cord can make an audio difference in a system.

Gene,
what about us-esoteric-designers that use and follow
a 'scientific' process to design an after-market power cord.
A power cord did win a 'Golden-Ear' award while back...
was the selection a mistake, bought, or per chance maybe
the power cord did what it clamed !

Noise is a subtle problem. How to control 'noise' in an audio
system has evaded many manufactures. Since most, if not all,
audio equipment use an unbalanced power source, low levels
of nosie permeate through the audio-system.
The high side of the supply is 'filtered' and the 'noise' is
coupled to the refernce side or common-ground.
Using a metal chasis allows this 'noise' to be induced into
all of the circuits in an audio system. Even though this 'noise'
is low in magnetude, the random energy of this noise interferes
and is impinged upon various components of an amplifier.

60 Hz, even 120 Hz or 180 Hz [etc.[ ripple 'noise' is managable
to a great extent, but what if there is a other 'noise' that is
un-'filtered'.
To filter the other sources of 'noise' they can be controlled either
all along the various circuit stages or 'controlled' at its source.

This 'noise' is in the 1 - 15 MHz area as was determined by using
an HP Network Analyzer: via the S-21 parameter and displyed on
a SWR print-out.

The best way for you the test out our findings is to make your
own power cord.

Of course you have credible evidence from a DBT comparison to support any and all of your claims, right???
Who can verify your claims? Who has, that has a standing in the industry, not rags glorious meaningless adjectives??? Oh, no one.
But, no one has made the Barnum Effect obsolete yet so you have nothing to worry about a market for such silly cables of yours as I presume you supposedly design them and sell them.
