John (Jmcgrogan2), yes, as you indicated we rarely disagree, and I always view your experience and your posts with great respect. And my perception has been that what you’ve said in your post above represents a belief that is shared by many and perhaps the majority of audiophiles.
Nevertheless, as I see it an expectation that a given power cord design will result in effects on the sound that are consistent and predictable when used to power a variety of components that may be completely different designs in just about every conceivably relevant respect, that are being powered by AC having unpredictable and widely varying voltage and noise characteristics, that are being used in conjunction with other components that can be assumed to have widely differing sensitivities to digital (or other) noise that may be coupled into them, that are being used in conjunction with other components and interconnect configurations that can be assumed to have widely differing susceptibility to ground loop-related issues, that may draw vastly differing amounts of current and have vastly different fluctuations in that draw, and that may even be performing completely different functions, is fundamentally irreconcilable with an understanding of how this stuff works. And IMO is therefore a misconception, probably resulting in most cases from extrapolating too broadly from personal experience, and reinforced by marketing hyperbole and popular mythology.
FWIW, though, aside from the reference to power cords being tone controls, I would agree with **everything** in your post if the word “signature” were changed to the word “effect.” Especially when it comes to power cords.
