AudioQuest - Chicago - Bulk Analog Audio RCA Interconnect Cable (Spool)

Every March 17 on St. Patrick’s Day, New York City merely paints a green line down the center of its Fifth Avenue parade route—a stunt easily pulled off by any city—but only Chicago dyes an entire river the perfect shade of emerald green to honor Irish culture. 

AudioQuest has engineered their Chicago RCA Bulk Interconnect cables with their Hard-Cell Foam insulation and Solid Long-Grain Copper (LGC) conductors. Constructed of superior materials and assembled with precision; their Chicago RCA Bulk interconnect cables are some of the best-sounding interconnect cables available.

AudioQuest's Chicago Bulk cable is suitable for RCA applications using the applicable terminations. Please see the Termination Manual for more information. AudioQuest recommends the use of their proprietary connectors and termination tool for best results.

Hard-Cell Foam (HCF) Insulation ensures critical signal-pair geometry. Any solid material adjacent to a conductor is actually part of an imperfect circuit. Wire insulation and circuit board materials all absorb energy. Some of this energy is stored and then released as distortion. Hard-Cell Foam Insulation is similar to the Foamed-PE used in our more affordable Bridges & Falls cables, and is nitrogen-injected to create air pockets. Because nitrogen (like air) does not absorb energy and therefore does not release any energy from or into the conductor, distortion is reduced. In addition, the stiffness of the material allows the cable's conductors to maintain a stable relationship along the cable's full length, producing a stable impedance character and further minimizing distortion.

Solid Long-Grain Copper (LGC) allows a smoother and clearer sound than cables using regular OFHC (Oxygen-Free High-Conductivity) copper. Solid conductors prevent strand interaction, a major source of distortion. The surface quality is critical because a conductor can be considered as a rail-guide for both the electric fields within a conductor, and for the magnetic fields outside the conductor. LGC has fewer oxides within the conducting material, less impurities, less grain boundaries, and definitively better performance.

Specifically designed for single-ended applications, Double-Balanced 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.
