Audioquest Chicago Stereo Phono / RCA Cable 0.5m (Pair) Overview
The AudioQuest Chicago RCA Phono Cable builds is the first cable in the company’s Rivers and Mystical Horses range of analogue interconnects. Featuring much of the same cable architecture as seen in the brand’s Evergreen series of interconnects, Chicago takes this a few steps further to deliver exceptional audio quality. Innovatively, Chicago separates the positive and negative currents into two individual runs of cables, each with separate exterior jackets. This configuration significantly reduces cross talk and contamination between polarities, enhancing isolation. Beneath the tactile green braided jacket, a Nitrogen-Injected Hard-Cell Foam Insulator creates air pockets within the material. By using nitrogen, which, like air, does not absorb energy or release any into the conductor, distortion is reduced. Additionally, this design adds stiffness and rigidity, ensuring the cable's conductors maintain stability and further minimizing distortion.

Full Description
View Full Description
Chicago is the first cable in the 'Rivers' series of analogue interconnects by AudioQuest. Chicago uses solid long-grain copper conductors in a double-balanced geometry, this produces a smoother and clearer sound. While the 'Hard Cell Foam Insulation' allows the conductors in the cable to maintain the same relationship with each other along the full length of the cable, ensuring that the characteristic impedance of the cable is consistent.
Solid Long Grain Copper Conductors
Solid conductors eliminate strand-interaction distortion. Chicago’s solid Long-Grain Copper allows a smoother and clearer sound than cables using regular OFHC (Oxygen-Free High-Conductivity) copper. OFHC is a general metal industry specification regarding “loss” without any concern for distortion. LGC has fewer oxides within the conducting material, less impurities, less grain boundaries, and definitively better performance.
Hard Cell Foam Insulation
This insulation is used exclusively in most of AudioQuest’s video and digital audio cables. Similar to Foamed-PE, it is nitrogen-injected to create air pockets. ‘Hard’ foam is used because the stiffness of the material allows the conductors in the cable to maintain the same relationship with each other along the full length of the cable, thus ensuring that the characteristic impedance of the cable is consistent.
Metal Layer Noise Dissipation System
100% shield coverage is easy. Preventing captured RF Interference from modulating the equipment’s ground reference requires AQ’s Noise-Dissipation System. Noise-Dissipation System prevents a significant amount of RFI from reaching the equipment’s ground plane.
Double Balanced Geometry
Two ideal audio conductors separate from the cable’s shield. Not only does this prevent the shield from being used as an inferior audio path, but it further optimizes sound quality by only grounding the shield at one end, reducing system ground-plane modulation.
Cold Welded Plugs
Two ideal audio conductors separate from the cable’s shield. Not only does this prevent the shield from being used as an inferior audio path, but it further optimizes sound quality by only grounding the shield at one end, reducing system ground-plane modulation.
