Regarding the $24/foot in-wall power cabling, I would certainly envision that it might make a difference in many applications, to a greater or lesser degree depending on many variables. Including the length that is required; whether the incoming AC voltage at the particular location happens to be greater than or less than the voltage the particular components were designed to sound best at; the magnitude and spectral characteristics of whatever noise may be riding on that AC; whether the power amp is biased in class A or AB or D (which affects the extent to which the current it draws fluctuates with the dynamics of the music); the susceptibility of the components in the system to ground loop issues, which can also be dependent on how they are interconnected; and countless other variables involving the design of the particular components in the system.
However I also see no reason to rule out the possibility that depending on all of those variables the results that would be provided in many cases by the $24/foot wiring might be worse than ordinary Romex would provide, rather than better. Certainly from a subjective standpoint, at least.
