Cablesson Ivuna Optical 2m /2 Metre cable is designed to give you a smooth, dynamic, undistorted and clear performance for all your digital sound needs. The sound quality of all the channels, whether two or five or more, are dependent on the Cablesson Ivuna Optical Cable to deliver an undistorted, smooth, clear and dynamic performance, while the plug's brass ferrule provides ideal light transmission and the highest quality sound. Bare in mind, an audio or video signal cannot be improved upon—it's as good as it's going to get once it leaves your amp, DVD or Blu-ray player, whatever component you're running. So why bother with a high-end cable? Simple: the signal can't be improved, but it can be damaged significantly and a lesser-quality cable leaves your signal wide-open to instabilities.
