Jerry, it's more than a little difficult to take such reports seriously. From the standpoint of basic principles of audio technology there's not even a plausible reason set forth why replacing the power cord that the manufacturer supplied could make an audible difference. They would be sabotaging their own product by supplying a cord inadequate to allow for the performance they'd worked hard to design and manufacture. Audio equipment has a relatively low demand for power compared to such more demanding items as hairdryers and hotplates, and the cords supplied are more than adequate for the purpose.
Your own use of an expensive Analysis Plus cord previously would seem to indicate that you were hardly in the category of a "skeptic" previously and didn't have to be "shocked" into becoming a "believer", as you've mentioned. Looking to Bob Harley for information on audio matters would also seem to indicate that you're willing to take seriously the bizarre concepts of "high end" audio which he frequently supports despite the lack of any factual basis.
No, it isn't necessary for everyone to continuously reinvent the wheel and personally try these strange products before labeling them as ridiculously expensive scams. Properly controlled double blind listening tests have failed to validate the claims of those marketing magic power cords, cables, players, amplifiers, etc. to the gullible.
