Power cables of your choice, and why?

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.

All LessLoss Power Cables with the  exception of one (integrated) is Puritan Audio Designs. All my IC are also Puritan Audio Design and speaker cables. 

Yes you will hear the difference with the LessLoss cables C-Marc Classic and the Classic Entropic (dac and Innuos Statement). 

Zenwave PSR power cables on my preamp and phono stage. They are incredibly revealing and very neutral. On my Pass amp, I use a Zenwave PCR cable. Also very revealing, but just a slight bit of warmth that the silver cables don’t have. 
I also use a Triode Wire Labs Obsession on the PS for my Weiss DAC. Also a very nice pc. I had bought it used to replace an AQ Hurricane, which was just too bass heavy for me.
