D.H. Labs has always recognized the critical role the dielectric plays in the performance of high- end audio cables. We pioneered the use of high performance dielectric materials (such as PTFE Teflon) in affordable cables and connectors starting in 1992, and we continue to lead the industry in this area.
Although Teflon is widely regarded as the best available dielectric material, it became apparent to us that a new (better) approach was needed to take audio cable design to the next level. This realization led to the development of the air-teflon matrix dielectric, which we simply call Air Matrix. The ultimate low-density dielectric, Air Matrix is a mixture of PTFE Teflon and air. (It is actually 60% air!) Unlike foam dielectrics, which basically consist of solid plastic containing air bubbles, the uniformity of Air Matrix is so high that a powerful microscope is required to see its texture, which resembles a fine matrix (hence the name). A byproduct of this high uniformity is that Air Matrix maintains excellent dielectric performance to beyond 17 Gigahertz, compared to about 3 Gigahertz for the best foams.
As you can see from the above chart, the dielectric constant of the Air Matrix dielectric material approaches that of a perfect vacuum!
Compared to solid Teflon, cables made with the Air Matrix dielectric exhibit lower capacitance, lower inductance, improved phase stability, more uniform attenuation vs. frequency specs, and reduced tribo-electric noise. These improved electrical characteristics allow excellent compatibility with the widest range of associated equipment. For an audio cable, this means open, clear and transparent sound, with unequalled soundstage and imaging properties. These improvements are most apparent with low level signals, making Air Matrix the ideal dielectric for interconnect cables. For this reason, our Air Matrix interconnect has become a favorite of demanding audiophiles, and also of recording studios for use on the world's finest microphones.
