About the AudioQuest RCA Noise-Stopper Caps
Put a cap on interference
Put a cap on interference
You can't see it, but radio-frequency (RF) and electromagnetic (EM) interference is all around us. Cell phones, computers, microwave ovens, and loads of other devices generate this electrical noise. That noise can be picked up by sensitive audio components a number of ways, including through open RCA and XLR inputs. RF interference is particularly problematic for high-performance audio gear, harming dynamics and clarity.
To reduce the amount of interference entering your system, try "capping" all unused RCA inputs. You may be pleasantly surprised by a deeper background silence and subtle, previously unheard details emerging from your system.
What's in the box:

These actually worked! I hear lower levels of quiescent noise from my Anthem preamplifier and amplifier after implementing the "AudioQuest RCA Noise-Stopper Caps" on the dozen RCA inputs.

These actually worked!
Andrew from Capitola, CA on 10/4/2018
These actually worked! I hear lower levels of quiescent noise from my Anthem preamplifier and amplifier after implementing the "AudioQuest RCA Noise-Stopper Caps" on the dozen RCA inputs.
Pros: The pro, they work. You will experience much lower levels of quiescent noise from your preamplifier and amplifier after implementing on all RCA inputs.
Cons: The con, all AudioQuest products prices are high for some family budgets. However, when you spend thousands of dollars on preamplifier and amplifier, the cost is not bad.

Noise caps
NevadaDon from Nevada on 6/18/2015
They look good. They're a little loose fitting right out of the box but with a VERY SLIGHT squeeze with a pair of needlenosed pliers, work perfectly. At least they're not an overly tight fit like Monster Cable's RCA plugs where you think your going to tear the jack out of your receiver when you unplug them.
Pros:
Cons: A bit on the expensive side.

AudioQuest RCA Noise-Stopper Caps
Crutchfield customer from Port Orchard, WA on 9/7/2014
Well made, fit well. An incremental improvement. Not sure how much of an audible difference these caps make, but for the price, they are a piece of the audiophile's puzzle in the quest for the illusive "silent soundstage".
Pros:
Cons:
