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

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.

So let me ask a question.

I am in the construction field, I notice sometimes that a 14 gauge SJ extension cord is not suitable for some heavy power tools, making the breaker trip. Why would we (audio enthusiasts) then plug 8 or 9 audio devices into one power conditioner/surge protector. To me this is like plugging 9 drills into one cord. That would never work. If we are worried about our amps getting the most voltage when it is needed, we would certainly not plug the amp into a multiple outlet device? Would we?

 I am not trying to down play the importance of an after maket power cord, I am willing to learn or at least listen to why we would do this. Is it that our audio equipment draws so little power that it is ok? And then it really does not matter?

 To me, this is a hobby, I take maybe to serious. When I hear music on the job site coming through a radio and then listen at home it brings a smile to my face. I just ordered a couple of moderately priced after market power cords for my tube Amp and tube Preamp. Even if I do not hear a difference (unless it is worse sounding) I will keep them. As I did measure there length to thread through my rack in a very neat and secure way. And mainly to keep the power cords on one side of the rack and the speaker and interconnects on the other side. I fell its always good to keep these far apart when you can.
