AudioQuest Sydney Interconnect Cable

This cable is specifically designed to connect devices with a 3.5mm headphone output—such as a smartphone, tablet, or portable digital audio player—to equipment with RCA inputs, like a stereo receiver, integrated amplifier, or powered speakers.

The Perfect-Surface Copper+ (PSC+) features an exceptionally smooth and pure surface. By minimizing the number of grain boundaries within the metal, it reduces the harshness and distortion often found in standard copper cables, resulting in a cleaner, more refined sound.

Polyethylene Air-Tube insulation is used because air absorbs almost no energy. By keeping the insulation material to a minimum, the cable avoids the energy absorption and subsequent signal distortion that can make audio sound 'out-of-focus' or muddy.

Cold-welding creates a permanent, solder-free connection between the cable and the plug. Solder is often a source of distortion, so by eliminating it and using direct-silver plating over pure copper, the connection maintains signal integrity and clarity.

Yes, especially if you have a lot of electronic devices nearby. This system uses carbon-based layers to absorb radio frequency (RF) interference before it can modulate the audio signal, which helps lower the noise floor and allows for a quieter, more dynamic listening experience.

While any cable length introduces some resistance, the high-quality materials and geometry in this cable are designed to minimize signal degradation over longer runs. At 8 meters, you can expect consistent performance, though it is always best to keep cable runs as short as practically possible to maintain the highest fidelity.
