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?

Have recently tried a variety of power cords including Luna Orange, Audio Art and Triode Wire labs ( still breaking in).  They all are a step up from stock cords.  The Luna is special; very rich and great timbre; but more costly and very stiff cord.  
Soniquil Power Cable by Raven Audio.
1.5/M $184
2/M $224
3/M $274
Very well built and huge bang for the buck!

The Audio Art cables you mentioned are quite good. I am using their budget power cord on my McIntosh MA6600 Integrated and it certainly is much better than the stock power cord.  It isn’t even close.
