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?

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. 





Contact Chris at VH Audio about his Trans power cable.  It is a new one and he hasn't posted the particulars on it yet.  I purchased one and it is the typical high quality that his products are known for.

My entire audio system equipped with Audio Art power cables.  They are very reasonable priced especially when they are on sale. Furthermore, the fit and finish are excellent.
