AudioQuest Sydney Cable

This cable is designed to connect devices with a 3.5mm headphone jack—such as smartphones, tablets, or portable digital audio players—to audio equipment with RCA inputs, like integrated amplifiers, receivers, or powered speakers.

Solder can often act as a point of resistance or impurity in the signal path. Cold-welding creates a permanent, high-pressure connection that maintains the integrity of the metal, ensuring a cleaner signal transfer.

This system acts as a shield against radio-frequency interference. By dissipating this noise before it reaches your equipment, it prevents the harshness often associated with high-frequency interference, resulting in a more natural sound.

Standard insulation can sometimes absorb energy and release it back into the signal, which causes distortion. Air is an excellent insulator that absorbs very little energy, helping the cable preserve the dynamic contrasts and timing of your music.

PSC+ is a high-purity copper with an ultra-smooth surface. By minimizing grain boundaries and surface irregularities within the metal, it significantly reduces distortion compared to standard copper cables.
