Keep in mind that a component’s power transformer makes a very effective low-pass filter that has little response to RF frequencies. In other words, RF interference rarely gets transferred to the transformer’s secondary winding. 

 

 

In normal (aka differential) mode, this is true. But then you'll also have a bank of reservoir caps to help with the filtering. However its not the case for common mode, particularly if the transformer's a toroidal.

Quite true, I didn’t mention it because I thought it muddied the waters to my main point, which is that these huge and hugely expensive boutique power cords cannot possibly have any effect on the sound.

 

Given that you do seem to accept that its CM noise which is the issue and isn't going to be much filtered by the mains trafo its just a small step to envisage a particular design of mains cable to act as a distributed common-mode choke.
