Secure Connectivity: Best RCA Stereo Audio Cables
RCA stereo audio cables are used to connect a wide variety of sources to amplifiers or receivers, and to connect discrete components together such as preamps, power amps, equalizers and surround sound processors. Typically, these cables carry line level signals (-10 dbV at roughly .3 volts) which are susceptible to interference from radio signals (RFI) and electromagnetic noise from AC cords, transformers, and motors (EMF interference). Given that these cables often cross one another, or touch power cords, good shielding is very important. And, with the low voltages involved, signal loss must be kept to a minimum.
High-quality RCA cables will use better conductors (copper or sometimes even silver) with gold-plated connectors. In general, thicker conductors are better. But, low capacitance is also important because higher values can cause high frequency attenuation.
You can spend an awful lot of money for RCA cables which yield diminishing marginal returns. Our ratings are for 6-foot cables, focused on overall value as much as quality of conductors, connectors, and insulation.
No matter what you need it for, we have a list of best RCA stereo audio cable in 2021 for you to help you decide what product is best to buy.

Detailing the Best RCA Stereo Audio Cables of 2021
Before we get started, please keep in mind you will need two of these cables to connect stereo gear so the price is times two. But there is no doubt that this is a top-of-the-line RCA cable at a reasonable price. Mogami cables are found in the world's finest recording studios, and Mogami wire is used inside of expensive microphones and audiophile gear.
The Mogami RCA-RCA cable features their Neglex oxygen-free copper conductors for low capacitance and best sonics, and a high-density spiral shield to prevent noise and interference from affecting the music. RCA male connectors are gold-plated for corrosion resistance and best conductivity. The outer jacket is a tough yet flexible PVC material.
With a lifetime warranty, quality materials and construction, and a well-earned reputation for musical fidelity, the Mogami Gold RCA 6-foot cable is our top pick. You can't go wrong - just remember you'll need two.
Blue Jeans products are known for being great values in the world of higher end cables, and the LC-1 RCA cable is no different. This is an RCA designed especially for rejection of interference and low capacitance. The copper shield is double-braided. The inner copper conductor is surrounded by a polyethylene material to minimize capacitance for zero loss of higher frequencies.
This is a cable that is a little easier to flex which could be a consideration if you are dealing with tight spaces and turns. Also note that, if you need a longer version of this cable for in-wall routing, the jacket is CM rated. The Blue Jeans LC-1 might be the perfect connector for your top end audio system.
The AR PR131 Pro II Stereo RCA audio cable is a true bargain in the world of quality interconnects. This cable offers many features found in more expensive choices. It has a double layer of shielding to prevent picking up noise and interference, and uses oxygen-free copper conductors to ensure full-fidelity sound. All connections are silver soldered, a feature of premium cables. And, the RCA male connectors are 24K gold plated.
The only thing keeping this from being our best pick is the fact that the capacitance figures are not listed, nor are specifics on the jacket. If you have an average-to-good audio system, and cannot justify spending more, this is a super choice.
This RCA audio cable from Belkin finds itself in our best lists for good reasons: two layers of shielding, high grade copper conductors, and gold-plated connectors.
For shielding, an aluminum and Mylar shield works with a braided copper shield to prevent the pick up of noise and interference from a variety of sources. The inner conductor is made of 99.9 percent pure copper for consistent electrical properties. The surrounding dielectric material helps maintain low capacitance for better high frequency response. And to top it off, gold-plated connectors equal best conductivity combined with resistant to corrosion.
The PureAV RCA Audio Cable, while not the best, is a nice choice and upgrade from flimsy interconnects packed along with many components.
