Which of these power cords ?

As the old prospector said: "There's gold in them thar hills!"

Buy Pangea and stop worrying! To believe that the "grass is greener" over there is to be caught up in a neurotic obsession!

You can certainly hear differences in power cables , if your equipment is up to allowing you to hear it.
Then it becomes a matter of how much difference you can hear. I have owned the Purist Audio Dominus Fluid power cord as well as the Dominus Fluid speaker cables and the Interconnects. They are the best cables that I have ever heard..IMO.
So, you have to decide how much better any are vs. what you have . You can only do this by trying them in your system

In review:

• Group A. thinks power cords make no difference
  
• Group B. think it's worth spending $800 or more on a power cord and they can make a big difference

Question is
- Will a $90 or a $150 power cord sound any better than the stock ones?

Wow so many choices thats your money its up to you.
