Many custom installers use Wireworld HDMI cables simply because they work in situations where others don’t. Even though HDMI video is generally excellent to begin with, the higher speed and lower noise of Wireworld HDMI cables reduces pixel noise, improving contrast, color saturation and depth perception. On the other hand, HDMI audio is prone to jitter losses, making the cables connecting source components to the receiver/processor the most important audio cables in the system. Therefore, we recommend upgrading the source cables as the first step to appreciating the benefits of Wireworld HDMI cables.
