In 1984, Matthew Bond, trained in physics and electronics theory, was looking for ways to improve the performance of audio components and the wire used within an audio system. As early as the mid 1970s and early 1980s, Matthew Bond had experimented with solid core conductors of different diameters. He hypothesized that an ‘optimum diameter’ of 18 AWG (American Wire Gauge) or 1 millimeter was ideal for audio frequencies because there was minimal high frequency attenuation caused by the principle known as skin effect.
Matthew Bond’s work was supported by research work from the NBS or the National Bureau of Standards in the 1930s and confirmed later by Stereophile Magazine in July 1988 in a table presented as the DC to AC resistance ratio versus frequency, in wires of different diameters. Matthew Bond is credited with the invention of solid-core wires for audio use, because his work predates any of the early solid-core wires developed for use in audio in England at the time.
In 1984 Matthew founded TARA Labs (The Absolute Reference Audio Labs) in Sydney, Australia. The first commercial speaker cables from Matthew Bond were the Phase II speaker cable, a solid core design. In 1990, Matthew Bond invented the world’s first cable to have a floating conductor unterminated at one end that would allow for an increased high-frequency bandwidth to be coupled to the signal carrying conductors (US patent No. 5033091). Later, a control device inside a box fitted to the cable (The Temporal Continuum) allowed the user to adjust the amount of high frequency energy to be heard.
In 1992, Matthew Bond invented Rectangular Solid Core cables. These ribbon-like conductors were solid with a rectangular cross section. Rectangular conductors can be made in specific proportions (width and height), and this provides for the tuning of the frequency response of a conductor.
The conductors used in Matthew Bond Audio Analog Reference Interconnect cables are Pure 6N Silver solid core conductors. The soft annealed solid core conductors are Six-Nines™ pure silver, or 99.9999% pure. The term ‘annealing’ refers to the method whereby a conductor can be made softer and more conductive.
