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.

I've gone through a bunch of PC's from Signal cable Magic, Silver Ref., Digital, to several Wireworld from150.00 to over 500.00 each.
Also DH Labs, Cardas, and others. By far the best have been the very costly Kubala-sosna Emotions, that I use now. But next to them I like the very affordable Signal Cable Magic versions.
