Which of these power cords ?


I'm looking to upgrade my sound with upgraded power cords. Given I've got a tube preamp, 2 mono block tube amps, Aurender DAC and 2 Martin Logan speakers - we're talking up to 7 power cords so I'd like to keep the total cost for all of them to $1000ish. 

And some suggest going with one brand, to get the biggest benefit.

Brands on short list include:
Suggestions?

I would wager that those who spend the coin have a problem with confirmation bias.
That can’t be the case for those who initially doubt that a different power cord would make an audible difference. And many audiophiles start out as skeptics, so there’s obviously another mechanism at work here.
... if McIntosh is saying their power cables do the job just fine and that your better off buying music etc., then that’s good enough for my ears.
Now that looks like an extraordinary example of confirmation bias. You seem willing to accept the claim at face value, rather than listen for yourself.

Incidentally, on what do you base your suggestion that McIntosh "is saying their power cables do the job just fine?"
That's a quote from a Mc source.

Cleeds you're free to spend your coin on the cable. Until I see an independent review showing that there is a real need to spend on one, I'll stick with the manufacturer's recommendation.

For what its worth I don't have hardly any experience with different manufacturers of pc, interconnects or speaker wire. But it was recommended to me by the cable company to use dh labs with my equipment (Rogue) and have never found the need to change. And as far as do pc make a difference in sound in a word YES! they do. And I know this to be true because I unknowing did a double blind test on myself with the pc to my amp. I installed it and totally forgot that I did and when I went to listen to my system that night it blew me away how well it sounded and took me a few minutes to figure out why, the power cord! Now I know are system can have good sounding days as well as bad ones for varies reason but I know for a fact this was not a psychoacoustics effect but it was do to a better pc.
