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:

For that kind of money I would definitely consider signal cables which is on your list best of luck and enjoy the holidays
I tried Pangea on the equipment in my audio rack and they sucked all the life out of my system.  Where I did use them (AC9SE) were powering the woofers in my Golden Ear Triton Reference speakers.  They work the bass just fine.  I use all Shunyata power cords elsewhere in both of my systems.
Make your own and get better sound and save money.  ( I wouldn't overlook those Wireworld Electras from hctf *(above)
Some of the companies you listed have a trial period with a return policy. Take advantage of this.
I agree that Cullen is a best buy. I have some thousand dollar Audience cables but since I discovered the Cullen Crossover PC, I've been adding them to my system. They have a neutral signature and present realistic sonics with detail and a spacious soundstage.
