about to jump into the power cord foray

Musicnoise,think of all the money you have saved.We power cord users sure are stupid.

Blindjim some assumptions that enter into this;
First there is the assumption "everyone" has a system revealing enough to hear a difference.
Second" everyone 's" hearing is anatomically able to hear the differences.
Third " everyone" wants to hear more detail, dynamics etc.,

Blindjim, while you make some very good points, I think you and Musicnoise are talking about different things.

You're 100% right when you talk about personal, subjective things like attraction, favorite foods, movies - even your favorite song or musician.

That said, the ability of a piece of AV equipment to work properly is highly dependent on objective electronics. For example, we can't deny that a CD player's ability to accurately retrieve and convert the data on the disc depends on it's specifications.
Whether we "like" the resulting sound of a particular player is a different matter; most of us are aware that the many combinations and arrangements of components in a CD player/amp etc can affect the sound in a way we might like or dislike, but it still has to adhere to basic EE principles or it wont work.

The trouble with PC's for people like Musicnoise and me is that they are not complex electronics; they are just copper wire with a plug on each end, carrying raw mains voltage to your hifi's power supply, and don't carry complex signals like speaker cables and IC's.
To me it's a bit like thinking my car will run better if I use the gold-plated gas bowser hose instead of the rubber one; as long as the fuel gets from one end to another unchanged, then the car will go as intended.

my advise is to try a mid priced or low priced model from one of the internet vendors that offers a trial period. If you hear the diff, great then move on the experimenting between brands. Try voodoo, signal, element etc.

If not, return it, your only out the price of shipping...
