AudioQuest Storm Series is the best power cord I have tried. Using Hurricanes throughout my system. I think two things stand out with the AQ cords. They have a very low impedance and they are dead quiet. Great at reducing background noise and creating a very black background. I am also using a PS Audio P20 which is an amazing AC regenerator. The combination takes all of my components to another level of performance. Very large detailed sound stage, great imaging, no compression on complex or loud passages. I have tried numerous power cords over the years and found very little difference if any until I tried the Storm Series cords.
