Let's face it: there are two schools of thought when it comes to audio cables. There's one camp that says "Cables don't matter!" and another that says "Yes they do — I've heard the difference!" AudioQuest believes that a cable's job is all about damage control and that a cable can definitely make a difference by limiting the harm dome to the original audio signal. With its Sydney cables, AudioQuest has gone to great lengths to minimize the harm, so the musicality of your original source can shine through. You might not expect a cable this thin and lightweight to deliver such great sound, but AudioQuest makes it happen with a combination of advanced materials and design techniques.

Solid Perfect-Surface Copper+ (PSC+) conductors

The perfect cable would be one that adds nothing to the original signal — no noise, no distortion. A cable's conductor material has a lot to do with how close it gets to this ideal. Sydney features conductors made from a material called "Perfect-Surface Copper+." PSC+ starts with ultra-pure copper, formed into solid (not stranded) conductors with an astonishingly smooth surface. The end result: clean, low-distortion signal transfer for transparent sound.

Advanced shielding, insulation, and cable geometry

An advanced 3-layer shielding system eliminates noise due to RFI (radio frequency interference) — the mortal enemy of good sound. A highly inert Polyethylene Air-Tube material provides insulation with minimal signal distortion and better sonic "focus." AudioQuest's double-balanced cable geometry separates the ground and shield paths for clean, quiet performance.

Cold-welded, direct silver-plated connectors

Sydney's connectors are made from high-purity "Purple Copper," which outperforms more common connector materials where it counts — in the listening room. They're also cold-welded, rather than soldered, which eliminates a common source of distortion found in many other audio cables. A direct silver-plating process further enhances signal transfer, for even better clarity.

This cable is equipped with stereo mini (3.5mm) connectors at each end. Stereo RCA and mini-to-RCA versions are also available.

Product Highlights:

  • length: 2 meters/6.6 feet
  • stereo cable with a male miniplug connector at each end (3.5mm)
  • solid Perfect-Surface Copper+ (PSC+) conductors for super-clean, transparent sound
  • Polyethylene Air-Tube insulation lowers distortion for less of the "out-of-focus" effect common to other insulation materials
  • carbon-based, 3-layer NDS (Noise Dissipation System) shields against RF interference
  • double-balanced asymmetrical cable geometry separates the ground and shield for quieter performance
  • dark gray and black braided jacket
  • cold-welded, direct silver-plated pure "Purple Copper" mini plugs feature a solder-less design for lower distortion
  • warranty: 5 years
  • Our 60-day money-back guarantee

Wow, what a difference!

Crutchfield Customer Review (What's this?)

I am using this cable to connect a Sony MP3 player to an Oppo portable DAC outputting to Shure SE846 in-ear earphones. With chamber music, the soundstage has widened with each instrument clearly positioned. I'm hearing details never heard before. Magnificent sound! Purchased through Crutchfield, an authorized online dealer. Few places carry this item.



good sound for a reasonable price

Crutchfield Customer Review (What's this?)

Purchased this last month to connect the DAC on my computer to my speakers system. The sound is very nice and the mid rage and treble have resolution and detail. The base is also good, but slightly more recessed. Overall nice sounding cable.

Pros: Good detail in treble and midrange

Cons: Slightly more recessed base

Product Research


Sidney Series Stereo Audio Minijack Cable: The AudioQuest Sidney stereo audio minijack cable is terminated by a silver-plated male 3.5mm stereo connector on each end. The AudioQuest Sidney stereo audio minijack cable is available in the following lengths.

  • 0.6 meter (2')
  • 1 meter (3' 4")
  • 2 meter (6' 7")
  • 3 meter (10')

Solid Perfect-Surface Copper+ Conductors (PSC+): Perfect-Surface Copper+ has an astonishingly smooth and pure surface. Proprietary metal-processing technology protects the wire's surface at every stage of drawing and fabrication. When high-purity low-oxide copper is kept as soft, pure and smooth as possible, it becomes a wonderfully low-distortion PSC+ conductor. PSC+ is manufactured by applying the same exceptional technology to an ultra-pure copper. The resulting sound quality is even more focused and simply less in the way. All of Sidney's conductors are solid. Electrical and magnetic interaction between strands in a conventional cable is the greatest source of distortion, often causing a somewhat dirty, harsh sound. Solid conductors are fundamental toward achieving Sidney's very clean sound.

Polyethylene Air-Tube Insulation: Any solid material adjacent to a conductor is actually part of an imperfect circuit. Wire insulation and circuit board materials all absorb energy (loss). Some of this energy is stored and then released as distortion. All of Sydney's conductors use PE Air-Tube Insulation because air absorbs next to no energy, and Polyethylene is low-loss and has a benign distortion profile. PE Air-Tube Insulation causes much less of the out-of-focus effect common to other materials.

Carbon-Based, 3-Layer Noise-Dissipation System (NDS): 100% shield coverage is easy; preventing captured RF Interference from modulating the equipment's ground reference requires AQ's Noise-Dissipation System. Metal and Carbon-Loaded synthetics prevent most RFI from reaching the equipment's ground plane.

Double-Balanced Asymmetrical Geometry: Purposely designed for single-ended applications, Double-Balanced Asymmetrical Geometry offers a relatively lower impedance on the ground for a richer, and more dynamic experience. While many single-ended cable designs use a single path for both the ground and the shield, Double-Balanced designs separate the two for cleaner, quieter performance.

Cold-Welded, Direct-Silver Pated Pure "Purple-Copper" Plugs: This plug design allows for a connection devoid of solder, which is a common source of distortion. Because the ground shells are stamped instead of machined, the metal can be chosen for low distortion. Purple-Copper offers a cleaner, clearer sound over nickel-plated or OFHC metals commonly found in competing manufacturers' plugs. Direct-Silver Plating offers one more important step toward greater clarity and doing no harm to the signal.

Directional: Arrows on the connectors indicate the preferred signal path from the source component to the input.
