Furutech vs Audioquest Power Cables

Hello everyone, my first post here. I'm in the process of upgrading power cables and wondering if anyone here has first-hand experience testing out Furutech's Nanoflux power cables vs high-end Audioquest cables such as Hurricane/Firebird/Dragon. In order for me to try them out, I will need to pay for them and test them out and then return one for a refund via an online store as I can't find any distributor who carries these cables in my area. Anyone A/B these and can comment on their general characteristics and attributes? Thanks for any help!
Great recommendation on the power cable shootout.
I'd also like to know what experience you have with different power cords. I'm not a cynic when it comes to the benefits of upgrading. I am wondering if there's a noticeable difference between a $500 cord and $3000. Unlike components, the quality of the actual materials used in, say, a Cullen Crossover II or ZenWave's cords and one of the big boys like AudioQuest/Shunyata/Furutech is a zero. Components use better materials with little to no whizbang creating notably higher costs. These hyper expensive power cables seem to leverage the whizbang for increased cost.

Maybe I've just created another thread... I'm curious to the OP's experience so we can give better options.
safebelayer (I assume that you do rock climbing), there truly is a difference in the materials applied in higher cost power cables.  This is also true in their shielding.  There are different types of copper, silver, how they are extruded, how the plating process is done, dielectric system, and the list goes on.
Then the question is, can you hear a difference when using the higher cost power cables, the ones with more expensive materials and production costs?  If you can then you have satisfaction.  If you can not, then no reason to waste your hard earned cash.  But my point is, there is indeed a difference in the quality of materials between less costly and more costly power cables.
Would you trust your life to belaying with heavy jute cord or high-quality climbing cable?
Do you have a dedicated power line with high end fuse?
This might be a worthwhile improvement, before investing more into power cables. 
After having a 20A HC Hurricane connected to my Niagara 7000 for a year now, I too began to wonder if the power cord was too bottom up in sound. I really wanted to try a Dragon but, lets just say I’m not rich.
I decided to make one on my own. I used 10 gauge .9999 pure soft silver wire and the best Teflon oversized tubing I could find. I covered the tubing with some granite mesh from Parts Express. I terminated the cables with Furutech F-50 NCF fittings. Heck, I even braided it like the Dragon.

To my surprise the Hurricane was holding back my system. My new power cord brought so much more life to the music it is awesome.

Now, if I could only figure out how to make one of those dialectic things...

BTW, my Hurricane is now connected to my Audioquest 1200 which powers my 2 JL F-113 subs.
