Power cable Advice...

Well if I had the best amplifier in the world, and matched it with the finest speakers in the world, I would probably just use lamp cord too. 

Any heavy gauge, well-made power cable will do. Cost is not proportional to sound quality. Don't be suckered.

Grover Huffman Pharoah is a phenomenal power cable that I have in my reference system on my JC1 monoblocks as well as on my Puritan power conditioner.  They were around 750 bucks each for 6 feet, I think.

"The Finest In the World. Probably."

My goodness. :)

Oh, and @jaymarkj  I've got some Grover IC's and have used his speaker cables- fine stuff indeed.

Here is another suggestion:

Audio Envy make good power cords that are very flexible and light weight, and I like the results.
