Musicians, painters, poets, and pioneers alike have been inspired and seduced by the beautiful aspen. With its slender trunk and long, delicate limbs, the aspen is known and loved for the soothing song conjured by its leaves-an array of rich green, brilliant yellow, or fiery red fans-that flutter and whir in even the slightest wind. The ancient Greeks fashioned magical crowns and protective shields from those same singing leaves, early Native Americans treated fevers and swollen joints with tea made from the aspen's bark, and weary travelers prize the tree's inner flesh for its life-sustaining nutrients.
This cable uses a carefully finessed combination of Perfect-Surface Copper (PSC) and extremely high purity Perfect-Surface Copper+ (PSC+) conductors. The astonishingly smooth and pure Perfect-Surface eliminates harshness and greatly increases clarity compared to OFHC, OCC, 8N and other coppers. Extremely high-purity PSC+ further minimizes distortion caused by grain boundaries, which exist within any metal conductor.
This cable's negative conductors are covered with partially conductive Carbon-Loaded Polyethylene. This remarkable material reduces radio-frequency garbage being fed back into the amplifier. The sonic benefit is exactly the same reduction in "hash" and improved dimensionality that comes whenever RF interference is reduced in an audio circuit. In addition, a carbon layer damps interaction between positive and negative conductors, and an external Carbon-Based NDS System reduces external interference.
All AQ "Tree" Series cables have an inner circular array of positive conductors spiraling in one direction, around which the negative conductors spiral in the opposite direction. This makes possible the significant performance advantage of having the positive and negative conductors cross each other instead of being parallel. The critical need for positive and negative to have a fixed non-changing relationship is ensured as the negative and positive groups are in fact two tubes with a perfectly consistent relationship. The result is an astonishing clarity, like focusing a camera lens you had no idea was so far out of focus.
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. Tower, however, uses air-filled Foamed-Polyethylene Insulation on both conductors. Because air absorbs next to no energy and Polyethylene is low-loss and has a benign distortion profile, Foamed-PE, with its high air content, causes much less of the out-of-focus effect common to other materials.
All insulation between two or more conductors is also a dielectric whose properties will affect the integrity of the signal. When the dielectric is unbiased, dielectric-involvement (absorption and non-linear release of energy) causes different amounts of time delay (phase shift) for different frequencies and energy levels, which is a real problem for very time-sensitive multi-octave audio. The inclusion of an RF Trap (developed for AudioQuest’s Niagara Series of power products), ensures that radio-frequency noise will not be induced into the signal conductors from the DBS field elements.
