THE DIGITAL AC is an excellent cable for any digital based component, creating a smoother, more "analog environment" for audio and video. Uniquely engineered specifically for the elimination of digital based noise, it very effectively eliminates what we call digititis, the harshness and background noise present and very difficult to remove in all digital sources. Most all devices that plug into a wall outlet act as noise sources creating an invisible shower of high frequency energy causing sophisticated electronics to error and perform well below their capabilities. Even the finest audio and video component's generate noise, limiting themselves of fine detail and resolution.
