I have a Linn Ikemi and have found very little difference in the sound of after market power cords. I had a Purist Audio rev.b on it, yes it was very difficult to keep it from dragging the Ikemi off of the shelf! There was not an improvement with this PC. I have had an AZ Krakatoa on it, and have a VH Audio flavor 4. I prefer the flavor 4 over the others and it is light. If I weren't ADD, OCD, I could have been content with the stock PC.
