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

Inna, you misunderstand what I said. Regardless of what your incoming line voltage is (mine is constantly between 120 and 122 volts) If you take a quality digital volt meter, read the line voltage at the end of the wire feeding the receptacle, hook up the receptacle and read the voltage at the output of the receptacle - on a cheep, standard grade receptacles, it is possible to see as much as a .3 voltage drop; on a hospital grade outlet, I guarantee you will see no voltage drop.
Considering the standard for US line voltage is 120V +/- 5%, @ 60Hz, (even though, nearly all power supply companies are more stringent than that) even the .3 Voltage loss of a standard receptacle is somewhat insignificant, but it does attest to the standard of quality of hospital  grade receptacles. The notion that it takes something more or different than a hospital grade receptacle to be a adequate receptacle for home audio - is absurd....Jim 

As both an audiophile and technician for 40+ years I have a VERY hard time with the idea that either a fancy outlet or power cord can or should make ANY audible difference in your or my system. If they really did, why wouldn’t most, if not all, of the better manufacturers include something of the sort with their expensive gear??? If it made their gear sound better, they’d be all over it. Why not? It would be a cheap selling point. AC is AC, it doesn’t do anything except deliver power to your gear. I don’t pretend to know everything, but that seems completely logical to me.

A better outlet may grip your plugs tighter, not a bad thing, I’ve replaced a few sloppy ones myself. If the attached power cord can comfortably handle the current demands of what it’s supplying, it can do no more. A gold plated/Rhodium/Sasquatch approved outlet is still just an outlet. I can't get drunk enough to believe otherwise :)

Keep your power lines away from your signal lines, sure. Install a dedicated high current line for your system, sure. Spend a hundred bucks on an outlet or hundreds on a power cord?? .............Your money. If it makes you happy, spend it.

I’m not saying that some folks don’t "hear" differences, or at least think they do. Your experience is not for me to question. I simply think it’s more the power of suggestion than reality. If you paid good money for a tweek and BELIEVE it will sound better, it probably does, at least to you.

Sad day in audiotown. The nay-sayers have invaded the place.. Like an infestation.

Yeah, sad day every day. More and more incompetent people trying to invade the place and space. This does make America great, no doubt.
