Power Cords


I currently have Wireworld Silver Electra power cords with upgraded Platinum plugs. I had two 1M Wireworld Platinum power cords, but rearranged my system and required longer cords. Yesterday I borrowed two Shunyata Sigma NR power cords. On the first note my wife softly said, "that sounds better". She said it was clearer. I listened for a couple hours, changing the power cords a couple of times. In my system and to my ears this is my conclusion:
The Sigma's are cleaner, definitely has more bass, a dead silent and completely black background. The Wireworld cords are more detailed, with a wider soundstage and better spacing/separation of instruments. All things considered I'll keep my Wireworld, but I'm curious to listen to other power cords.
After inserting the Sigma's I just don't understand how anyone that listened to different power cords could conclude that they can't hear a difference. There is a difference, but like any other component the individual has to decide if the change is worth it. $6K for two power cords is relatively expensive. Expensive, but oddly maybe a good value? In my system there was a definite improvement with better bass impact and articulation. Would spending $6K or just changing amplifiers yield similar results? As with most components there are trade-offs...is there a power cord out there that has the benefits of the Sigma's and Wireworld Silver Electra's? If so, at what cost?

Huh? They asked you not to write the details of the Hurricane power cord? That’s pretty funny since the details are provided on the Audioquest web page for the Hurricane. Don’t believe me?

Man, I kew better than to ask bo a question, but he'd been so reasonable here lately. 
Audioquest is not able to describe in detail over their cables. It is very simple to explain why. Most systems they use for presentation are incomplete.

They only talk a little about technical details, but this does not say anything about the real properties and what it does in your system.

I know exactley the difference between many Audioquest cables. When you test by Tru-Fi it gives you a very detailed insight of all the different parts in sound.

That makes is so much easier to understand what the cable does in your system. When you would like to change the sound and stage of your system you need to know exactly which properties you take out and which you bring in.

But people do audio by trail and error. But this does not give you any information about the properties you took out and brought in with another cable, amp, source, loudspeaker etc.

This is why it is one big F. gambling. You never can control and guide your system to the sound and stage you want. Even when I aks to people; do you have any idea how voices and instruments sound and how they are projected into space?

Most say that they have no idea. When I aks how they want to adjust and control their system they often start to laugh. And say: you are fully right that we don’t know what we are doing.

When you create audio by properties a cable becomes a lot more important than how all other shops and companies in audio sell and use them. For them it is often some extra money and they will say: it wil improve the sound and quality.

They cannot work and think in properties, it will be one big gamble for them. In our way of creating a system cables are equal important than other parts in our system. When you use a cable by Tru-Fi the level of effectiveness becomes so much greater.

Very simple to explain; we can use more different properties out of any Audioquest cable. Because most brands and products in audio are incomplete in properties based on facts. I can and will proof this.

Most loudspeakers are incomplete again based on facts, so you never can use the full potential of an Audioquest cable. You are limited by the fact that you use different parts which are incomplete.

It is very easy to explain. Because what is missing will never be there. Audio has nothing to do with brands, products or price. All these parts does not garantee you anything at all.

Music and sound are based and founded on different properties. This is what you need to understand and build the sound and stage you want. There is no other way to do it correctly.

All the other ways of doing it are pure gambling.
