Power cables of your choice, and why?

Cullen Crossover ll, Furutech 4.1,   Because they sound good.

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.  

@audiostick I am running a 14 gauge Kimber PK14 Base made for EMM Labs on my Meitner DAC as I type this. It’s basically the same cable as the PK10 Ascent except it’s 14 gauge and features lower quality Wattgate connectors. It’s not as resolving as the PK10 Ascent but it’s most likely due to connectors. 
I had 14 gauge Audience pc on source components before and there’s nothing wrong with these cables being n source vs 10 gauge. But the opposite is also true - 10 gauge cables work great on source components and amps which makes them more universal. That’s why I prefer 10 gauge cables they’re just more versatile.
