Power cable education needed


Hi everyone. I need some education on power cables. I have been reading that a good power cable is vital to a good sounding system. If that is true wouldn’t the companies the make the components include a good power cable to insure their product sounds the best that it can ? Should I evaluate the power cables in all of the components in my system?

dchang05:  This is so true. Each of us can hear slight changes in our very familiar systems that others can not. It is not because we have 24K golden ears and others have 18K, but rather we're more used to the system. Also it has to be apiece of music we listen to a lot. For this thread it means we have to do the work. taking others opinions from their systems won't mean much in our listening rooms.

My wife and my friends wives are listening to music too. So I do not understand why that is a tall tell?
@johnnyaudiogoon,

Thanks for explaining your experiment.

To tell you the truth, I cannot explain the improvement you are hearing.
The only scientific explanation I can give is the fact that maybe, if your house installation is SO GOOD (ie your chain is already so thick) and much better than both your power cables, it then exposed the shortcomings of your power cables themselves.

Do you have a dedicated special high current wire in your house to the outlet your amp is connected ? 

I cannot think of any other engineering explanation :-)
