AudioQuest Chicago RCA to RCA Cable (Pair) at Vinyl Sound Toronto Canada

The AudioQuest Chicago is a double-balanced RCA analog interconnect from AudioQuest (Irvine, California, USA), available as a matched pair at Vinyl Sound in Toronto, Canada. Built around Long-Grain Copper (LGC) conductors, a Triple-Layer Noise-Dissipation System, and double-balanced geometry, the Chicago is engineered to connect preamplifiers, integrated amplifiers, CD players, DACs, and phono stages with a stable, low-noise signal path. Polyethylene foam or air-tube insulation reduces dielectric coloration, keeping the Chicago well above generic RCA interconnects in both technical design and audible performance.

Long-Grain Copper Conductors and Double-Balanced Geometry

The AudioQuest Chicago uses Long-Grain Copper conductors refined to minimize the grain boundaries that introduce distortion as an audio signal travels along the conductor. Fewer grain boundaries mean lower accumulated noise and less high-frequency smearing across the audible bandwidth, preserving the transient accuracy and low-level detail that distinguish high-performance analog interconnects from commodity cables. The double-balanced geometry controls the spatial relationship between signal and ground conductors throughout the cable, maintaining consistent impedance and reducing the cable's susceptibility to externally induced noise. This geometry also ensures that both channels of the stereo pair behave identically, supporting accurate stereo imaging and channel separation.

Triple-Layer Noise-Dissipation System and Foam or Air-Tube Insulation

The Chicago's Triple-Layer Noise-Dissipation System applies three stages of shielding to prevent captured RFI from reaching and modulating the ground-reference conductor. Conventional single-layer shields absorb interference and drain it directly to component ground, introducing a form of ground-plane distortion that affects the entire audio signal. The triple-layer configuration on the Chicago interposes additional shield material between the captured noise and the ground connection, progressively absorbing and reflecting RF energy before it can cause ground modulation. Conductors are insulated with polyethylene foam or air-tube geometry, both of which minimize the contact area between the metal conductor and its insulation to reduce dielectric energy storage, a source of phase shift and dynamic compression that affects perceived musical naturalness.

Key Features

• Long-Grain Copper (LGC) Conductors: Refined copper with reduced grain boundaries lowers accumulated conductor distortion and high-frequency noise across the audio bandwidth.
• Double-Balanced Geometry: Controlled spatial relationship between signal and ground conductors maintains consistent impedance and reduces noise susceptibility along the full cable length.
• Triple-Layer Noise-Dissipation System: Three-stage shielding progressively absorbs and reflects RFI before noise reaches the ground reference, preventing the ground modulation caused by conventional single-layer shield designs.
• Polyethylene Foam or Air-Tube Insulation: Low-density insulation geometries minimize conductor-to-insulation contact, reducing dielectric energy storage and preserving transient accuracy and dynamic contrast.
• Sold as a Matched Pair: Both channels are matched for consistent electrical performance, supporting accurate stereo imaging and channel balance.

Frequently Asked Questions

What is the AudioQuest Chicago RCA cable?

The AudioQuest Chicago is a double-balanced RCA-to-RCA analog interconnect sold as a matched stereo pair, built with Long-Grain Copper conductors, polyethylene foam or air-tube insulation, and a Triple-Layer Noise-Dissipation System. It is designed for connecting stereo audio components including preamplifiers, integrated amplifiers, CD players, DACs, streamers, and phono stages. The Chicago is part of the AudioQuest analog interconnect range and is available at Vinyl Sound in Toronto, Canada.

How does the AudioQuest Chicago compare to the AudioQuest Evergreen or Golden Gate RCA cables?

The AudioQuest Chicago sits above the Evergreen and Golden Gate in the AudioQuest RCA interconnect lineup. The Evergreen is an entry-level cable using stranded Long-Grain Copper and a single-layer shield, while the Golden Gate adds solid conductors and a more refined noise-dissipation configuration. The Chicago advances further with double-balanced geometry and a Triple-Layer Noise-Dissipation System, making it a meaningfully more capable analog interconnect for mid-to-high-performance stereo systems. Compared to competitors such as the Kimber Kable PBJ or WireWorld Oasis 8, the Chicago's triple-layer NDS addresses ground-reference modulation at a level those cables do not.

What components can the AudioQuest Chicago RCA cable connect?

The AudioQuest Chicago connects any two audio components with standard RCA analog outputs and inputs, including CD players, network streamers, DACs, preamplifiers, integrated amplifiers, AV receivers, phono stages, turntables with fixed-output tonearms, and tape decks. It is sold as a stereo pair for left and right channel connections simultaneously. For turntable applications where a dedicated ground wire is required, AudioQuest's phono-specific interconnects such as the Golden Gate or Mackenzie with integrated ground wire are the more appropriate choice.

What is double-balanced geometry in an RCA cable?

Double-balanced geometry in an RCA interconnect refers to a conductor arrangement where both the signal and ground conductors are symmetrically controlled in their spatial relationship throughout the cable length. In a standard coaxial RCA cable, the center conductor carries the signal and the outer shield simultaneously serves as the ground return and the RF barrier, creating a conflict between its noise-rejection and signal-reference roles. A double-balanced geometry separates and controls both conductors more deliberately, reducing the impedance variations and noise pickup that result from a simple coaxial arrangement and improving channel consistency across a stereo pair.

Does the AudioQuest Chicago work with a turntable or phono stage?

The AudioQuest Chicago can be used between a phono stage output and an integrated amplifier or preamplifier input, as this is a standard line-level RCA connection. For the connection between the turntable tonearm and the phono stage input, a cable with an integrated ground wire is required, which the Chicago does not include. AudioQuest's dedicated phono interconnects, including the Golden Gate, Mackenzie, and Angel, are designed specifically for that tonearm-to-phono-stage connection with the appropriate ground wire included.

Where can I buy the AudioQuest Chicago RCA cable in Toronto or Canada?

The AudioQuest Chicago RCA interconnect is available at Vinyl Sound, an authorized AudioQuest dealer in Toronto, Canada. Vinyl Sound carries the AudioQuest analog interconnect lineup in-store and online, with full manufacturer warranty support for Canadian customers.

Why does insulation type matter in an analog interconnect cable?

All insulation materials surrounding a conductor act as dielectrics, absorbing energy from the audio signal and releasing it in a non-linear, frequency-dependent manner that introduces phase shift and dynamic compression into the signal. Denser insulation materials with higher dielectric constants, such as standard PVC, absorb and release more energy than low-density foamed or air-tube geometries. The AudioQuest Chicago uses polyethylene foam or air-tube insulation to minimize this dielectric effect, preserving the transient sharpness and dynamic contrast of the original signal more accurately than cables using conventional solid insulation.
