Do powercords make a difference in sound?

This goes with the last link:

Wanted to thank the reviewers for identifying themselves.

Rwwear, this is old nonsense. Most people ignored Randi's challenge, but one accepted it. Randi set such conditions that no one ever had a chance to take the challenge.

Lissnr, ask yourself why Rwwear and Paperw8 bother to spend so much time and effort at their cause? Why would they care if you try different cables? I have suspicions, but I really don't know or care.

It's your cause TB. Some just don't believe in it plain and simple. As a matter of fact in the real world hardly anyone believes it. I'm not saying you are lying. I just need proof that I can believe.

Rwwear, no one owes you proof. I doubt seriously if many audiophiles avoid trying different power cords because several people, imbued with the "laws of EE," claim they could make no difference.
