How can power cords make a difference?


I have read many threads about how "wonderful" this or that power cord made my system sound. For the life of me, how in the world can a 3 ft power cord make an improvement? Each manufacturer supplys a power cord.I can't imagine them puting something on thier unit that would not meet thier needs. After all, the power comes from the utility company into your house, you run a dedicated line to your equipment, you put a line conditioner/surge protector between your equipment and now you have clean consistant power then magically you have great music. What can 3 feet of $200 0r more power cord make a differance? Sounds like expensive VODO! Am I missing something?

Edkoz, you should look into the archives as this thing has been covered ad naseum.
I completely agree with you regarding cords (congrats on not calling them chords), and you'll often see the most adament arguers are also those that insist double blind testing isn't necessary, as the "know what they hear".
If you've got EMI and RFI covered, you're good-to-go. Don't buy into the power cord silliness.
Snofun3 is so right. I don't know what I was thinking sending money to the late Bob Crump for his silly cords. I'm just totally delusional and the vast improvement they made was completely in my head and was a perfect example of that well-understood phenomenon, the placebo effect.

What's a-matter with you folks!? I upgraded my power cord and my amp looks way better.

Now you see, THAT's the problem. If you're going to thank God, you have to side with the believers. You must choose science or religion in this matter. Sorry, but there are no other paths to enlightened electricity.
