Which of these power cords ?

I can't believe manufacturers would all compromise the sound of their components by using inadequate power cords?
I can not believe that expensive power cords make an audible difference. At my rural home the current runs about 750 feet through aluminum cable from the last transformer to my service panel then another fifty or sixty feet through copper Romex cable from the service panel to the wall outlets for the stereo. A six foot power cord is at most .75 per cent of the total cable supplying power to the stereo. How can six feet of expensive power cord correct problems created the other 99.25 per cent of wire. I just don't buy it. That being said I am careful to use good quality power cords , usually the cords supplied by the manufacturer of the equipment.

" I can’t believe manufacturers would all compromise the sound of their components by using inadequate power cords?"

They are not in the business of power cords and better cords mean higher costs as most components have price point goals. Manufacturers will let the end user decide as there are hundreds of options.

Your second paragraph is a tired argument and has been hashed out in this and many other forums.

Not to mention manufacturers are usually the last to find out about these things. 

@Kingharold It's the same theory as all those high fidelity speakers having the right true sound but they all sound different.

I would suggest the Acrolink 4030. With goods plugs like Oyaide or Furutec
This is an option

However, 

Most important is the LENGTH of the cable. You will need ar least 1.5m (6 feet) . Power cables can act as filters and help reduce high frequency hash. If your system is fed with clean power to start with, everything will benefit. 

My system is wired with Acrolink from junction box to outlet and from outlet to equipment.
