AudioQuest Big Sur Interconnect Cable

This cable is designed for devices with a 3.5mm headphone jack—like smartphones, tablets, or portable media players—to connect to equipment with RCA inputs, such as home stereo receivers or powered speakers.

Solid conductors eliminate the interaction between strands, which is a major source of distortion in audio cables. Using Solid Perfect-Surface Copper+ ensures a cleaner, more precise signal path for your music.

This system acts as a shield to prevent radio frequency interference from contaminating your audio signal. By blocking external noise, it ensures the sound remains clear and free from the hum or static that can plague lower-quality cables.

Cold-welding avoids the use of solder, which can often create a weak point or introduce impurities at the connection. This method creates a permanent, high-integrity bond that maintains the purity of the signal from the cable to the connector.

Yes, this design separates the ground path from the signal path, which allows for a lower-impedance ground and a more dynamic, richer soundstage. It essentially optimizes the cable's internal structure to handle the audio signal more efficiently.
