I believe at best "Power Cords" is a local issue

Which may explain why your experiences differ from mine. I have switched power cords in and out without noticing and audible differences.

My primary amplifier that in total weighs 110 lbs, has a 55 lb behemoth separate "box" that the manual refers to "as treating or conditioning the power". So, maybe my amplifier came with a power conditioner as part of the package negating the need for an audiophile power cord. Although the power cord (s) that comes with it is a monster.

As far as my locale is concerned, power conditions differ *vastly* over the metropolitan area. For example, my parents live 5 miles away. Their (and their neighbors) power circumstances differ greatly from mine. While it is certainly not "uneven" like I have seen in some rural areas, it does not compare to the rock solid situation that I (generally) have in my neighborhood where most of the lines has been recently modernized and placed underground.

In addition, with the installation of a 6500 KHw solar panel system to my home came a major upgrade/improvement to the electrical system. That electrical upgrade did make a "difference" in my sound system.

As part of the solar system the house has a dedicated "Power Conditioner" and a "Power Conditioner Display" that constantly monitors the house "power condition" for even minor fluctuations, according to the manual. If there is a fluctuation that the power conditioner cannot correct in real time it shows up as a fault on the display. That has happened twice. I didn't necessarily "notice" anything, it just shows up as a fault.

I'm not suggesting that, my amplifier's dedicated power conditioner or the global power conditioner for my home duplicates anything that dedicated audiophile power conditioners may do. Perhaps it's apples and oranges. But I thought it may be of interest and it does show that power conditions can vary from area to area and even from house to house. This may determine whether one may hear differences in power cords.

Finally, I have asked a couple of audio "modders" why they don't include upgraded power cords as part of the extensive upgrades they make on gear. See the response of the late Allen Wright on this topic at link below.
