Air Matrix™ is a DH Labs exclusive material that is a honeycomb of air and PTFE. It is approximately 60% air and 40% PTFE. When viewed under a powerful microscope, it appears as a fine matrix, hence the name Air Matrix. The introduction of air, all but removes any sonic signature, while also significantly lowering capacitance and inductance. It is also physically soft and naturally dampens vibration. These features make it especially advantageous for low-level signals. We use it (in extruded form) in our Air Matrix & Pro Studio interconnects, and the D-750 digital cable. A proprietary tape-wrapped version is also used in our Revelation Interconnect.
