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?

Two cents worth of my lies.

I had an offer from the local power company to swap out my drop from the pole to the house. NO COST. WHY? It had been there since 1945.
They upgraded the service in the 80s from 8k to 20k for all the resident clusters, all HEAVY ALU. cable. BIG improvement. No more low voltage reading. EVERYTHING worked better.

But, again why my drop? LOL
The guy wanted the 75 year old copper cable. WHY? I asked WHY do you want THAT cable?  He explained he was serious stereo guy, and that copper would make some of the best speaker/interconnects/ect money could buy.

OK, then we went inside, he saw a FEW stereo systems. Vintage tube and New Mcintosh tube gear. He was amazed at the quality of the sound, of the newer C2500, all fixed up with op Amp upgrades la te da. Then he heard the old C20s, MC30s, MC60s, MC225s, MC240s and MC275s, all pairs all OLD, but restored with HIGH quality parts. The guy stops buy once a month to listen now. BTW the old copper stayed.

Knob and tube in my house. And yes if you turn off all the breakers, lest the three 20s (not knob and tube) I use for the stereo room is like NO OTHER. All my cabling is made by me.  Quality wire, Quality Terminals Voltage maint of 120 new 117 old gear, very, VERY, important , shielding where you can. I think I have under 500.00 USD invested, in all the cable combined, mostly pure copper, some pure silver (USAF surplus). NO CLAD or mixtures of copper/silver/gold, in my system.  ZERO floor noise, with the newer stuff, almost zip with tube gear. 

OH, I forgot MY new TIN Foil Hat! I paid 1500.00 USD. Just can't get the wife to go along with heating water in the fireplace, when I turn off the breakers, darn, heck, shoot, females!!! TURN DOWN THAT STEREO, yes dear.  The chickens will quit laying eggs! YES DEAR!!  Not really, she's a great sport. The chickens that is..
Hi cdc2,

I don't mean to rain on your parade but that leaves you $142.00 for each cord. Go to

audiobacon.net                           https://audiobacon.net/2019/08/17/27-audiophile-power-cables-reviewed/

It's a great online audio website, he did a fantastic review and compared 27 (I think) different power cords and gave his opinion of all of them. There were some great budget cords but even the budget cords were in the $250.00 - $500.00 price range. At $142.00 each, I think you would be wasting your money if you bought all 7 of them at the same time. Just my opinion. The way I would do it is buy 2 or 3 of them  to start with and put them on the most important pieces such as your sources whether that's the cd player or the dac or the streamer. Then as you save up enough money for the next round you can put them on your preamp or integrated amp. A good power cord can make a nice difference but at the $150.00 price point there's not a lot of good ones to choose from. Eventually it will make a big improvement in your whole system. Good luck with whatever you choose.

I can't believe manufacturers would all compromise the sound of their components by using inadequate power cords?
I can not believe that expensive power cords make an audible difference. At my rural home the current runs about 750 feet through aluminum cable from the last transformer to my service panel then another fifty or sixty feet through copper Romex cable from the service panel to the wall outlets for the stereo. A six foot power cord is at most .75 per cent of the total cable supplying power to the stereo. How can six feet of expensive power cord correct problems created the other 99.25 per cent of wire. I just don't buy it. That being said I am careful to use good quality power cords , usually the cords supplied by the manufacturer of the equipment.
