My house, as with most homes in North America use 14/2 copper wire to transfer 110V 15 amps of electricity from the panel to the outlet. Assuming there is a good connection at the panel and the outlet, and as long as the cable going from your outlet to your audio component is as good as 14/2, logic would dictate that the sound would be the same.
The theory of constraints says that you must work on the weakest link in a chain to make the chain stronger. In this case the weakest link would be the 14/2 wire in your walls.
I am not saying you and your buddies did not hear a difference. However, I am asking for some type of scientific proof. What is the scientific measurable basis for such a claim that a cable from the outlet to an audio component improves sound quality?
