AudioQuest RCA Evergreen
Overview of the AudioQuest RCA Evergreen
Analog audio interconnect cable named after the Evergreen Bridge connecting Seattle, Washington (USA) to the Bellevue area across Lake Washington. In all Bridges & Falls models, you’ll find higher-quality metals and more elaborate technologies, such as air-tube insulation, dielectric-bias system, and noise-dissipation system, at lower prices than ever before.
Note: In all Bridges & Falls Series cables, the right and left channels are housed together in one jacket and feature Asymmetrical-Double-Balanced geometry with separate high-quality positive and negative conductors. This design allows for a thin, flexible, and outstandingly versatile high-performance cable that can be assembled with a variety of current connectors – such as 3.5mm (male or female), DIN, and RCA. Note, however, that the connectors on the Bridges & Falls cables are necessarily fairly close together. If the L and R inputs of your components are more than 7.6 cm (3 inches) apart, please consider models from our Rivers or Elements series.
Double-Balanced Asymmetrical Geometry
Designed specifically for single-ended applications, Double-Balanced Asymmetrical geometry provides less impedance on ground for a fuller, more dynamic sound.
While many single-ended cables use a single path for both ground and shielding, double-balanced designs separate the two for a cleaner, quieter performance.
Metal Layer Noise Dissipation System (NDS)
Achieving 100 percent shielding is easy. To prevent “trapped” radio frequency (RF) interference from affecting the ground reference of the device, the AQ Noise Dissipation System (NDS) is required.
Conventional shielding absorbs noise rustling and then dissipates it to component ground; this modulates and distorts the critical reference ground plane, which in turn distorts the signal. The NDS “shields the screen” by picking up and reflecting most of the noise rustlingRF energy before it reaches the layer connected to ground.
Cold welded, gold plated connectors
This connector design allows connections without solder – as this is a common source of interference. Because the end sleeves are stamped rather than machined, the metal can be selected for low distortion rather than machinability.
Solid conductor made of long crystalline coupler (LGC)
Solid conductors prevent distortion caused by mutual interference of the strands. The solid long-crystalline copper (LGC) allows for a more balanced, clearer sound than cables with the usual oxygen-free, high-conductivity copper (OFHC). OFHC is a general metals industry specification that considers “losses” without any consideration of bias. LGC contains fewer oxides in the conductive material, fewer impurities, fewer grain boundaries, and offers significantly better performance.
Polyethylene foam insulation
Any solid material adjacent to a conductor becomes part of an incomplete electrical network. Wire insulation and PCB material absorb energy (losses). Some of this energy is stored and then released as distortion. Therefore, air-filled polyethylene foam insulation is used for both conductors because air absorbs almost no energy and polyethylene is low-loss and has a benign distortion profile. Thanks to the air in the polyethylene foam, it causes significantly less blurring effects than other materials.
