Power cable recommendations for wyred 4 sound Sti-Intergrated amp

Shunyata power cords are good however they can get pricey.
My suggestion is a lot of bang for the smaller dollar spent.
To beat the Raven Audio power cord (and a few other brands) you have to spend hundreds of dollars more.
I’m as guilty as anyone else and I’ll admit it, within several systems I have set up I own many expensive power cords. If you wanted more expensive suggestions I'd recommend in any order: High Fidelity power cords, Cerious Technology Matrix, Less Los C-Marc, Shunyata Anaconda Vx.

I suggest getting a home demo of Clarity Cable Vortex power cords. Google James Romeyn and I’m sure he will send you some to audition. All systems/preferences are different, but in my system I preferred Vortex power cords over Shunyata Sigmas, Wireworld Platinum, Audioquest Hurricanes, Audioquest Dragons, and High Fidelity CT-2 power cords. You results may differ.

+2, soix. 
I use Audio Envy in my system. I would recommend their Ocean Mega 3 for your Integrated. 
Stay away from Pangea!

Why don't you use their own (W$S) cables? They look good and are reasonably priced, especially if you stick with their standard connectors:
