Does coaxial sound better than RCA?
Both coaxial and RCA cables are designed to transmit audio signals from a source to an amplifier or receiver, and ultimately to your speakers. While both types of cables are capable of transmitting high-quality audio, there are some differences between the two that may affect the sound quality.
Coaxial cables typically offer better noise rejection and less signal loss than RCA cables. This is because coaxial cables have a shielded conductor, which helps to protect the signal from interference and noise. The result is a cleaner, more accurate signal, which can translate into better sound quality.
In contrast, RCA cables have a single conductor, which can be more susceptible to noise and interference. This can result in a less accurate signal and potentially lower sound quality.
That being said, the difference in sound quality between coaxial and RCA cables may not be noticeable in all situations. In many cases, the quality of your audio equipment, the distance between your components, and other factors may have a greater impact on sound quality than the type of cable you are using.
Ultimately, the best way to determine which type of cable will sound better for your particular setup is to try both and compare the results.
