"Later in the day AudioQuest power expert Garth Powell (who knows well more about A.C. power than do you, trust me), explains why A.C. cables make a significant audible difference in an audio system. Powell not only explains why, he demonstrates it here. You will hear the same piece of music played twice, once with a "stock" molded rubber power cord between the CD player and preamplifier and once with AudioQuest's least expensive power cord, the Thunder. Despite being recorded via a camcorder shotgun microphone you can easily hear the difference."
