powercords

@scar972 , there is logic to that, though we know that doesn’t always apply in audio.... source is critical, as well as their power supplies. Amps usually have robust power supplies, though a terrible cord can surely limit them. Source tend to have smaller supplies, as well as the fact that they are the beginning....

One question that I posed actually has not been answered in this thread, which is how would a power cord make a difference? I mean theoretically speaking. Would it not have to change the characteristic of electricity between the outlet itself and the component, and if so what characteristic is it changing? 
Running a cable the entire distance between the source and the recipient, such as from the CD player to a preamp, or an amplifier and speakers is one thing. But claiming that a small bit of cable tacked on the end of miles of a different cable can change-profoundly- electricity is something else.  What exactly is being changed?

lostinseattle,
I suspect you've read about this before since you've hit pretty much every "deniers" reason why it will not make a difference in your very first audiogon post. Give a couple aftermarket power cords a try & let us know what you think. 

What exactly is being changed?

Good luck getting an answer to that question.

Here’s the deal, if you hear it, then it is obviously doing something. What that is some feel hasn’t been explained, I’ve seen explanations from different manufacturers that claim different solutions in their products. Is that true? I can’t say. Are there ways to measure this? Again, I don’t know this either. Rather than say something isn’t happening because you cannot measure it, believe your ears, and develope ways to determine what is happening, if it interests you that much. I’d love to delve into that, but real life Dosnt present me with the time to do that, and I’d have to make some connections with the proper type of engineers who were open minded enough to help with that. So flor now, I’ll just enjoy what I hear. Much like I know cars have improved in horsepower, gas mileage, reliability, etc, over the years, but I don’t need to know the technical aspects of each things done to enjoy the benefits. I tend to look at the big picture and delve into details if needed, or there’s some desire to. My brother who teaches science is the opposite. For him to understand something, he has to see it built from the ground up, and understand each detail. Not that he doubts something until he does, but he does like to see it proven to him. I believe we went to the moon, was there to watch it on tv, but not in person, I didn’t develope the rockets or technology, but I understand the ideas used and believe we were actually there. There are some who don’t believe we were and it was all done on a studio set.
