Power cord? Why?


I see a lot of posts regarding power cords. I would like to know what sonic difference they actually make. Could anybody explain this in a simple way?

Thank you

So putting all things aside and the nit pick. I was a industrial as well as a medical x-ray technician for a number of years. So all this metal wire which is cryoed, constant casted, solid vs. stranded, welded, soldered and crimped still has stress fractures in the wire and in the weld or solder joint. I can't even believe that some companies have gone to welding the wire to plugs. So as the metal expands and contracts with temperature variations and humidity, as it is bent in the application it is meant for, as it ages and becomes more brittle. What does all this falderal buy us. Not a darn thing except something neat to talk about.

You are starting to get it! The answer has nothing to with the things you just outlined. Try this: take all your audio cables and tie them together while still connected to your equipment. Play your system, the hazy sound you will hear is field contamination. Would it not be correct to say the field inside the cable is just as degrading as the field that bleeds to the outside? Now, there is a solution to this problem but that is for another time.
Corona, I understand what you are saying although you are very vague in your answer. So what is the point? Yes I know their is a solution, which hopefully will soon be a patented process.
Hahaha... as i've said before, it's too bad we can't get people together and "talk shop" without being afraid of losing what they consider "proprietary knowledge". While everybody has their "trade secrets", and i'm sure that some of these are quite ingenious, i don't think that any individual / group of individuals has ALL the answers. That's why it is great to be able to pick and choose the best ideas of the lot and incorporate them into your own DIY designs : ) Sean

A solution to what exactly? Corona, if there is field theory involved in your 'pulse' idea, I certainly hope there is an IEEE-level white paper with theory, modeling and measurements to back it up.

Why do I feel the world's next $2500 power cord coming on?
