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 DB 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, the 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. You'd hate to spend good money on a low-quality cable, so that's why we're here to help. We have curated this list of the best RCA stereo audio cables of 2022 for all your sound needs.
