AudioQuest Rocket 33, signal cable for speakers

The relationship between conductors defines a cable's most basic electrical values ​​(capacitance and inductance). However, even when those variables are kept in a reasonably neutral balance, the particular geometric relationship between conductors greatly affects the sound. Star-Quad geometry is not only vastly superior to conductors running in parallel, but also to the same conductors as two twisted pairs.

This cable uses a carefully refined combination of Long-Grain Copper (LGC) and extremely high-purity Perfect-Surface Copper (PSC). LGC has fewer oxides within the conducting material, fewer impurities, fewer grain boundaries and definitely better performance. The astonishingly smooth and pure PSC further eliminates harshness and greatly increases clarity.

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 dampens interaction between positive and negative conductors, and an external Carbon-Based Noise-Dissipation System reduces external interference.

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. This cable, 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.
