Power cords have a voice. They also have a different voice with different components of your system. Generally the greatest difference can be noticed at the source and working down the chain. Don't forget your subwoofer. Customers have reported significant power increases with the correct power cord. There are still some non-beleivers out there. I think they may have not matched the correct power cord to electronics. Be sure to choose a manufacturer that offers an audition period. Also be patient and allow the pc to burn in.
