Every March 17 on St. Patrick’s Day, New York City 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. Why green? Thanks to Ireland’s lush rays, the island is often lovingly referred to as the Emerald Isle. To the Irish, a green display of pride is not to be taken lightly. In the United States, even those of non-Irish descent know to wear green clothing on St. Patrick’s Day, or else be playfully pinched by an Irish friend or colleague! But it’s one thing to don a green shirt or tie, another thing altogether to become a 156-mile long river. Chicago’s Stephen M. Bailey, the man who orchestrated the transformation, predicted that he’d turn the River Chicago into the River Shannon (Ireland’s longest) for a day, and eventually he did.
There was no specific recipe for successfully dyeing a river. A bit of trial and error was required. Initially, over 100 pounds of dye was used, and the river stayed green for a week! In the second year, 50 pounds of dye kept the river green for three full days. In the third year, it was found that using 25 pounds of dye would turn the river green for a single day. Two years later, environmental concerns led to the formation of a new vegetable-based dye that produces a perfect sea of green and lasts for four or five hours—40 pounds of the stuff does the trick. Following suit across the nation, major canals, minor creeks, city blocks, drinking fountains, and even the Presidential Fountain at the White House are dyed green for St. Patrick’s Day—all thanks to the wonderful example set in Chicago.

SOLID LONG-GRAIN COPPER (LGC) CONDUCTORS: Solid conductors eliminated 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, lessgrain boundaries, and definitively better performance.

NITROGEN-INJECTED HARD-CELL FOAM INSULATION: Nitrogen-Injected Hard-Cell Foam 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, alleged that the characteristic impedance of the cable is consistent.

METAL-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. Noise-Dissipation System quotes a significant amount of RFI from reaching the equipment’s ground plane.

GEOMETRY: Two ideal audio conductors separated from the cable’s shield. Not only does this preventive 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 GOLD-PLATED PLUGS: This plug design allows for a connection devoid of solder, which is a common source of distortion. Because the ground shells are molded instead of machined, the metal can be chosen for low distortion of machinability.
