Can upgraded power cords help my setup?

Since this is an audio forum, I'll buy the island if it improves the soundstage & midrange of my system the way the above mentioned power cord has. Also, it has to be picturesque, warm, sunny, not riddled with rodents or biting insects, spiders, fly's (etc.), and as affordable as the Oyaide Tunami power cord. Deal?   

"....and as affordable as the Oyaide Tunami power cord."

One assumes a Tunami is a giant wave of tuna fish.

use the most expensive, fattest, grooviest looking power cord you can find - run it all the way back to your elec. co.s sub-station too

then pile Shakti Stones on top of it and sit back for the awesome!!

Geoff / Good one

Randy / Although that would probably be awesome, only a few feed (directly attached to the electronic device) is required

Penns / I trust my ears so am not interested in Cardas cable or what Cnet states
