Why would you disparage AudiogoN with such a ridiculous question? Are these forums for audiophiles, or trolls with nothing better to do? What a shame...
Pixel guy, you're missing the point. The six feet of the power cable is not the issue. It's the fact that one is connecting one's component to a power grid, with its noise on the line, fluctuations, and interference from some of your own appliances.
^^^ No doubt the power coming into the system affect the sound. This is why the sound seems to improve early in the morning and late at night when fewer people and industry are using the grid.However, some of that can be overcome with power cords that use filters, etc.
