Many attempts at improving the performance of audio cable appear in the prior art. For example, U.S. Pat. No. 4,628,151 for MULTI-STRAND CONDUCTOR CABLE HAVING ITS STRANDS ARRANGED ACCORDING TO THE GOLDEN SECTION, issued Dec. 9, 1986 to George F. Cardas teaches a cable system in which the ratio of sizes of individual conductor strands vary compared to one another by a ratio of approximately 0.62.

U.S. Pat. No. 4,767,890 for HIGH FIDELITY AUDIO CABLE, issued Aug. 30, 1988 to David L, Magnan teaches a cable construction wherein a ring of small conductors is arranged about the perimeter of a large diameter core. Spacers are used to support an outer shield at a predetermined distance away from the ring of small diameter “all skin” conductors.

U.S. Pat. No. 4,945,189 for ASYMMETRIC AUDIO CABLE FOR HIGH FIDELITY SIGNALS, issued Jul. 31, 1990 to Donald E. Palmer discloses an electrical conductor formed by two insulated strands, the second being wound helically around a substantially straight first conductor.

U.S. Pat. No. 4,980,517 for MULTI-STRAND ELECTRICAL CABLE, issued Dec. 25, 1990 also to George F. Cardas, discloses conductors wherein individual conductors of different sizes are arranged in particular geometries.

U.S. Pat. No. 5,064,966 for MULTIPLE SEGMENT AUDIO CABLE FOR HIGH FIDELITY SIGNALS, issued Nov. 12, 1991 to Donald E. Palmer discloses an electrical conductor formed from two insulated strands twisted together. However, one of the two strands is cut at a predetermined point to form a discontinuity therein.

U.S. Pat. No. 5,109,140 for HIGH FIDELITY AUDIO CABLE, issued Apr. 28, 1992 to Kha D. Nguyen teaches insulated conductors spaced-apart from one another and wrapped with a ferromagnetic foil.

U.S. Pat. No. 5,110,999 for AUDIOPHILE CABLE TRANSFERRING POWER SUBSTANTIALLY FREE FROM PHASE DELAYS, issued May 5, 1992 to Todd Barbera teaches geometry for a power cable wherein each of three conductors has multiple stands of different gauge cables twisted together.

U.S. Pat. No. 5,266,744 for LOW INDUCTANCE TRANSMISSION CABLE FOR LOW FREQUENCIES, issued Nov. 30, 1993 to Dwight L. Fitzmaurice, discloses substantially parallel coaxial transmission lines in close proximity to one another.

U.S. Pat. No. 5,376,758 for STABILIZED FLEXIBLE SPEAKER CABLE WITH DIVIDED CONDUCTORS, issued Dec. 27, 1994 to Ray L. Kimber teaches a set of speaker cables braided about an enlarged, flexible core to minimize electromagnetic field interactions between the conductors.

U.S. Pat. No. 6,005,193 for CABLE FOR TRANSMITTING ELECTRICAL IMPULSES, issued Dec. 21, 1999 to Mark L. Markel teaches another cable geometry wherein the conductors are substantially flat and arranged in a predetermined relationship to one another.

U.S. Pat. No. 6,066,799 for TWISTED-PAIR CABLE ASSEMBLE, issued May 23, 2000 to Steven Floyd Nugent, teaches a twisted-pair configuration wherein over one half of the twisted pair run, a second conductor of the twisted pair is insulated and uninsulated over the remainder of the run.

U.S. Pat. No. 6,388,188 for ELECTRICAL CABLE AND METHOD OF MANUFACTURING THE SAME, issued May 14, 2002 to Ian Harrison teaches a twisted cable configuration having two electrically conductive members and a third, electrically non-conductive member twisted together to control the geometrical relationship of the two electrically conductive members in relation to one another other.

U.S. Pat. No. 6,570,087 for DELTA MAGNETIC DE-FLUXING FOR LOW NOISE SIGNAL CABLES, issued May 27, 2003 to David Navone et al. teaches a specialized geometry for cables for conducting electrical signals in proximity to strong sources of electromagnetic interference.

U.S. Pat. No. 6,658,119 for AUDIO SIGNAL CABLE WITH PASSIVE NETWORK, issued Dec. 2, 2003 to Bruce A. Brisson et al. teaches a passive RC or RLC network imposed between a signal line and a ground line in or at a terminus of an audio cable.
