AudioQuest Analog-Audio Interconnect Cables – River Series (Chicago)
On St. Patrick’s Day, March 17, New York City simply paints a green line down the center of its Fifth Avenue parade route—a gimmick that any city could pull off—but only Chicago dyes an entire river an emerald green to commemorate Irish culture. What is the significance of the color green? Ireland is affectionately referred to as the Emerald Isle because of its beautiful nature. A green display of pride is not taken lightly by the Irish. Even people of non-Irish ancestry in the United States are aware that they must wear green apparel on St. Patrick’s Day or risk being pinched by an Irish friend or coworker! But wearing a green shirt or tie is one thing; transforming a 156-mile river is quite another. Stephen M. Bailey, the guy behind the transformation, boasted that he’d turn the Chicago River into the Shannon River (Ireland’s longest) for a day, which he eventually did.
There was no one-size-fits-all method for dyeing a river. A little trial and error were necessary. Over 100 pounds of dye were used at first, and the river remained green for a week! The river remained green for three days in the second year, thanks to 50 pounds of dye. It was discovered in the third year that using 25 pounds of dye will turn the river green for one day. Environmental concerns prompted the development of a new vegetable-based dye two years later that produces a flawless sea of green and lasts for four or five hours—40 pounds of the material is enough. Major canals, minor creeks, city blocks, drinking fountains, and even the Presidential Fountain at the White House are all colored green in honor of St. Patrick’s Day, thanks to Chicago’s inspiring example.
It’s simple to get 100 percent shield coverage. Noise-Dissipation from AQ is required to prevent collected radio-frequency interference (RFI) from altering the equipment’s ground reference. Traditional shield systems absorb noise/RF energy and then drain it to component ground, modulating and distorting the essential “reference” ground plane and causing signal distortion. Noise-Dissipation “shields the shield,” absorbing and reflecting the majority of noise/RF energy before it reaches the ground layer.
Double-Balanced Geometry, which is specifically developed for single-ended applications, provides a lower impedance on the ground for a richer and more dynamic experience. While many single-ended cable designs combine the ground and shield into a single path, Double-Balanced designs separate the two for cleaner, quieter performance.
Cold-Welded, Gold-Plated Terminations
This plug design eliminates the use of solder, which is a common cause of distortion. The approach uses a high-pressure technology instead of solder. The metal used for the ground shells can be chosen for minimal distortion rather than machinability because they are stamped rather than machined.
Hard-Cell Foam Insulation
Insulation made of hard-cell foam (HCF) assures crucial signal-pair geometry. An incomplete circuit consists of any solid material that is close to a conductor. Energy is absorbed by wire insulation and circuit board materials. Some of this energy is held before being released in the form of distortion. Hard-Cell Foam Insulation is nitrogen-injected to form air pockets, comparable to the Foamed-PE utilized in our more inexpensive Bridges & Falls cables. Distortion is reduced because nitrogen (like air) does not absorb energy and so does not discharge energy from or into the conductor. Furthermore, the rigidity of the material helps the conductors of the cable to retain a steady connection throughout its whole length, resulting in a stable impedance character and minimizing distortion.
Solid Long-Grain Copper (LGC) Conductors
Solid Long-Grain Copper (LGC) cables produce a smoother, cleaner sound than OFHC (Oxygen-Free High-Conductivity) copper cables. Strand interaction, a significant source of distortion, is avoided with solid conductors. Because a conductor can act as a rail guide for both electric and magnetic forces inside and outside of it, surface quality is crucial. LGC has fewer oxides in the conducting material, fewer impurities, and fewer grain boundaries, all of which contribute to improved performance.
