The Cardas Clear Digital Cable AES-EBU
Clear Digital AES/EBU employs a perfectly symmetrical tri-axial geometry by using air tubes to separate and suspend Cardas' PTFE taped, Matched Propagation conductors. Additional air tubes are arranged outside the core of the cable to place the braided shield in the perfect position. Additional shielding is provided by a carbon impregnated semi-conductive PTFE tape which works with the shield to dissipate noise.

Clear Digital SPDIF
State of the art coax digital has arrived. Flawless digital signal transmission using the legendary Matched Propagation technology. Applied to SPDIF (75 ohm) applications you are treated to completely neutral and transparent playback. This is the reference digital cable all others are measured by.
