Power cables of your choice, and why?

In one of my systems I'm using a mix of Shunyata Research Sigma X NR and Sigma V2 NR because they suppress noise and allow me to hear additional details and/or hear those details more clearly.

@lak that's how I felt/heard when my dealer lent me a Furutech Project V1 ac cord. Initially I thought things got darker but after a few days listening I put back my original cord and wow the noise heard in the soundstage was eye opening. The Furutech went back in and it was clearly less noise and more music. 

One that fits the equipment and has the right length. Try to keep excess cable length to a minimum. As power draw of most components is minute, I don't worry about cable thickness or anything of that sort. Poweramp uses Pass supplied cord. I trust Nelson did the right thing.  

I have found improvement swapping all other cable types in my system, but have yet to hear a difference with a power cable. I am not in denial or doubting it can happen, I guess I have not tried the right cable. All of my power cables are OCC copper and are a mix of Acoustic Zen, WW and Neotech. I have never tried anything in the $1K range or above, maybe I need to go higher.

Putting the awesome PC to one side seen in the Link 

The guidance shown in the link is the best methodology seen to date for learning how the use of a Power Cable effects the Audio System.

Everyone should carry out this methodology for assessing the Value of a PC.
