The compact copper Long-Grain of the Chicago RCA allows for better and clearer sound than cables that use standard OFHC (oxygen-free high conductivity) copper. The LGC has fewer oxides within the conductive material, fewer impurities, smaller grain boundaries, and definitively better performance.

The hard cellular foam insulation infused with nitrogen allows the conductors of the cable to maintain the same relationship among themselves along the length of the cable, thus ensuring that the characteristic complex resistance of the cable is consistent.

The noise system prevents the achievement of significant amounts of RFI at the equipment's grounding level.
