A certain online retailer asked me for a review of Pangea power cords..

Here and there people keep talking about ridiculously high priced cables can enhance sound quality. When seeing a 6-power cable is being priced as high as $3000, all I could was shaking my head! There are simple things that people just don't want to understand. Don't you think people at Pass Labs, McIntosh or Mark Levinson designed a $20,000 amp and included a power cable that would degrade the amp performance? Or as one asked earlier in this thread, "Can anyone explain to me how the last few feet of a power cord makes a difference when the rest of the house wiring is standard Romex copper wiring?" The answer is no difference, unless you switch from an Ikea extension cord. 

I bought the Pangea Audio Octet Premier XE for $150 on last year Black Friday. Instead of buying Pangea power cord, I built myself to avoid a dozen of 6ft-10ft power cord in a tight space using Wattgage connectors and Belden 19365 power cable. I ordered a couple of XLR cables from Blue Jeans Cable once then built them myself with the same material, Belden and Meutrik, and saved half of the the cost. My advice: If you love high end equipment, learn how to make your own cables with fine parts. Goldpoint SW2X-I is sold for $395. I made a box with exact parts for $50. The most expensive part was the Grayhill rotary switch for $15. the remaining were Neutrik connectors and silver soldering wire.

Having worked many years in the machine and tech end of a large, international, apparatus repair/manufacturing corporation, that manufactured and supplied everything from very large industrial machines and electrical components and supplies to residential electrical supplies - I can say for a fact that it's not sleepwalker's opinion that's fantasy.
While I do believe in quality hospital grade outlets, and good quality cables and cords - people who make wild claims about ridiculously priced outlets, cables and cords apparently know little or nothing about how electricity, from the grid to your component, actually works, or why and how components are designed and built to operate fully and properly on the standard household current of the country where they are to be used.
Companies who build $5k, $10k or 20k audio components, do not build them to sound bad with their supplied power cords, nor do they in any way imply the need of an expensive cord to make them sound better. If you buy a $10k amp and it doesn't sound absolutely glorious within the parameters it was designed to operate, I doubt that a $10k power cord or a $5k outlet will magically fix it. In that case, maybe you would be better off to just buy a $200.00 amp and put a $10k power cord and $5k outlet on that and save yourself a cool $4.8k...just sayn Jim

Ops make that - save yourself a cool $9.8k. Wow, you could buy another cord.

There are no $5Koutlets. One of the reasons I decided to upgrade outlets IS because even the very best are pretty cheap, compared to the high end powercords and IC. Sooner of later outlets WILL have versions that cost megabucks. The most expensive duplex (I thought was Furutech GTX NCF.. nooooo. There is some other 'blue that is retail over $400 now. Plus the Furutech are on sale at 20% to 50% off (but not everywhere)          
Back to PC.. I did decide to use some DH Labs AC wire with my Furutech plugs. It is breaking in, so not comments on sound. I may buy some Furutech wire too.. Thinking maybe try some.

As much as the build quality of the original ac9 impressed me, it did not match well with my Rowland Model 1.  The sound became very dull.  That said I have not heard the more recent iterations of this product.
