The story

Clear Cygnus Interconnect borrows the star-quad geometry and air-tube suspension of Clear Beyond, with four 25.5 AWG Matched Propagation conductors insulated in a double layer of PTFE tape rather than extruded PTFE. The composite shield sits on its own layer of larger air tubes, away from the signal conductors.

Cardas calls it very organic and dynamic, with a neutral tonal balance that keeps the Cardas character, and it works at almost any length in almost any system. Standard connectors are the Cardas GRMO RCA or CE XLR; the CG XLR used on Clear and Clear Beyond is available as a $400-per-pair upgrade.

Measure component-to-component along the real path, including the drop behind the rack, and round up to the next half metre. Use XLR when both components have true balanced connections; otherwise RCA. Cardas builds XLR and RCA versions at the same price. A pair covers one stereo connection; source to preamp, or preamp to power amp.

Key technologies

  • Matched Propagation Technology. US Patent 7,674,973: the propagation rate of the conductor is matched to that of the dielectric through the conductor's internal geometry, so the signal is not smeared in time.
  • Ultra Pure Cardas Copper. Grade 1, 99.9999% pure oxygen-free copper, drawn and annealed slowly through silver dies, then given a single poly-nylon coat to prevent oxidation and crosstalk between strands.
  • Golden Ratio scaled Litz conductors. Multi-stranded conductors in which each layer of strands steps up in size by 1:1.618 from the centre outward, a Cardas patent that controls strand resonance.
  • Air-tube suspension. Anti-static LDPE air tubes and carbon-impregnated PTFE tape hold the conductors in air; a second layer of tubes 1.618 times larger suspends the composite shield away from the signal path.
  • Made in Bandon, Oregon. Every Cardas cable is built and hand terminated at the Cardas factory on the southern Oregon coast and carries the Cardas lifetime cable warranty.
