AudioQuest’s RCA Noise-Stopper Caps have been doing their job on thousands and thousands of audio components for many years. Silently doing their job — keeping RF noise out of RCA inputs and outputs is all about wide-band silence.
That’s a bit of joke: One can’t hear RF Noise, but one easily hears the Transient Inter Modulation (TIM) distortion wide-band noise causes.
These new RCA Caps do exactly the same job AQ’s RCA caps have been doing for ages. But, thanks to the 23 springs now inside the Cap, they go on easily even over oversized RCA jacks, and they stay on securely over undersized RCA jacks.
The previous black-print-on-chrome version looked great. We think the new more substantial and ergonomically superior RCA caps look even a bit cooler in their white-on-black-nickel glory. We hope you agree.
Noise-Stopper Caps are also available for XLR-out, XLR-in, HDMI, RJ-45, and USB-A — though your unused USB jacks really should have an AudioQuest JitterBug FMJ pulling noise off the internal circuit and power bus.
