AudioQuest Noise-Stopper RCA Caps
Everyone knows that noise and distortion are bad for audio reproduction, destroying precious detail and smearing resolution.

Cover all the unused RCA inputs in your system with the AudioQuest RCA caps and keep this distortion from getting into your components. AudioQuest 's RCA caps slide right over unused RCA jacks and will provide both sonic and environmental protection.
