Yup.
Tornado because it sucks up all your cash and blows it away!
Please consider that an aftermarket power cable just delivers electrons from your existing in-wall, non-audiophile Romex cable, to the very same wiring in your AVR or AVP.
Does a 3' power cable somehow magically make electrons different somehow?
The short answer is no. The electrons don't need to be massaged with beer or sake, they don't care if someone found a way to extrude a single crystal copper conductor...
People buy this cr@p because they are chasing the dragon and convince themselves that quantum tunneling somehow means something. They have to believe it, too, because they spent something like $1000-$1700 on a flipping power cable that the manufacturer gives you for free!
In short, it has been pointed out that most of these companies don't even have real engineers on staff... but they have marketing heads for days!
Spend your money wisely on Better Speakers, and get yourself some decent quality pure copper speaker cable. Don't worry about the power cord, unless you plan to install your own special wiring from the Power Sub station to your home on your own private power poles! Oh, and rewire your house, install new outlets, oh and a special balanced sub-panel would be required too...
Oh, and I almost forgot: AH Drinking Game... Everybody take a shot!
