"For those of you that have already purchased LessLoss power cords, you know what this conditioner sounds like - It sounds like the power cords - but on steroids. Bring to mind every good thing that you like about the sound of the power cords, then multiply it by twenty, thirty, whatever. This conditioner imparts to your AC all the clarity, transparency and dynamic life that the cords impart, but more... much more."
