Power cables of your choice, and why?

@lanx0003, in response to your question, among the things you have missed are

Design and construction of the mains and IEC connector and the manner in which the cable is terminated into those connectors;

Design and construction of the cable dielectric;

Mechanical construction of the cable overall with respect to microphonics.

I was comparing $50–$80 power cables to high-end counterparts costing more than ten times as much. Is there any evidence that well-made cables like Pangea or Emotiva lack quality components or construction?

Second, I agree that dielectric properties matter, since capacitance is directly proportional to the dielectric constant. However, this is relevant mainly for audio signal quality in digital or analog interconnect cables. The effect of a power cable’s capacitance on audio signal quality is almost negligible. We’re talking about a few hundred picofarads in a typical 1.5–2 m power cable compared with tens of millions of picofarads from the capacitors placed before and after the regulated power supply.

Lastly, regarding the mechanical construction of cables: I’ve already discussed shielding and dielectric. For other mechanical properties such as vibration control and damping, check out the beefy power cables from those three brands (with thick jacket/filler/dual shielding). See how tight and rugged their build is before you judge how well they might reduce or eliminate vibration.

I just picked up a brand new Kimber PK10 Ascent a week ago. It was a rough ride for the first 70 hours to a point I had to walk away as I wasn’t able to listen for more than few minutes but I pressed on and let it cook. Improved after 70hrs and now I have about 160hrs and it’s more or less settled. I have it on my Meitner MA3i DAC and it’s awesome. Transparent, dynamic and natural sound. Excellent instrument separation even with large scale classical. It replaced Nordost Frey 2 and at a much lower cost!

I’m surprised I don’t read about these cables here more often. 
 

@audphile1 , Have you ever tried 14 Ga cables on your source components, or have you always just taken "the thicker, the better" approach and gone 10 Ga?

Approx. 1 year ago, for my stereo system,  I bought 5 new 6 foot ifi NOVA power cables as a bundle for $680 out the door including shipping from a private dealer on Audiomart to replace all the stock power cables.  At the same time, I also put in a audioquest duplex outlet.  I made these changes all at once, and I can tell they did make an improvement in sound. I would say smoothness, soundstage was improved, maybe also bass, but, not sure on that.  Note:  I also updated all my interconnects and speaker cables about 8 months later with OCC copper interconnects and huge low gauge IFC copper speaker cables.  This change made a more positive difference in the improvement of my sound than the Power cables.  Any harshness was gone, bass was greatly improved, and soundstage was also improved.  So, my point is, I would improve the speaker cables, interconnects first, then, the power cables.....  In addition, if you are running tower speakers (ie. lots of bass) with long lengths, then, inmho,  the most important upgrade is thick low gauge speaker cables.  I am using 7 gauge per speaker, approx. 3 or 4 gauge per speaker connection and 12 feet of length.  Of course, the longer the speaker cable length, the more the lower gauge makes a difference.   I hope this helps you.
