Cardas XLR Parsec 1m cable

The Quadlink long stood as a reference in the Cardas lineup for its musical character and warmth. The Parsec inherits its DNA while adding Matched Propagation technology, previously reserved for the Clear series. This combination results in a cable with a strong personality, more agile and more readable than its predecessor, without sacrificing the rounded midrange that built the brand’s reputation.

Geometry designed to control resonances

George Cardas built his reputation on applying the golden ratio to audio cable design. Patented in the mid-1980s, this approach consists of sizing each layer of strands according to the 1:1.618 ratio. The thinnest strands are located at the center of the conductor, the thickest on the periphery. The principle: no layer shares a common harmonic multiple with another, preventing resonances from adding up and coloring the signal.

The Parsec XLR pushes this logic further with Cross-field geometry. Each layer of strands is braided in the opposite direction from the previous one. This alternation reduces the dipole antenna effect that turns conventional cables into transmitters and receivers of electromagnetic interference. The tinned copper braided shield, kept at a distance from the conductors by compressed polyethylene air tubes, completes this protection system.

Conductors synchronized with their insulation

In a conventional cable, the electrical signal travels through the copper at the speed of light, but the energy stored in the dielectric (the insulation) is released about 20 to 30% more slowly. This offset causes a smearing of micro-information, a kind of blur on fine details and transients.

Cardas’ solution? Deliberately slow down propagation in the conductor so it coincides with that of the dielectric. This is the principle behind Matched Propagation conductors, achieved by precisely controlling the twist pitch of each Litz strand layer. The Parsec is the first cable in the Cross range to benefit from this technology, originally developed for the Clear series.

Copper, Kevlar, and Litz construction

The copper used here is Grade 1 OFC (Oxygen Free Copper) with 99.9999% purity, drawn through diamond dies in a hydrogen-reducing atmosphere. Each strand immediately receives a urethane insulating coating (Litz technique) that protects it from oxidation and prevents interactions between adjacent strands. This construction preserves the copper’s qualities over the long term.

The Kevlar central core ensures the mechanical stability of the whole. The cable does not deform under its own weight and maintains its geometry even after numerous handling operations. The outer jacket in Alcryn, an extruded elastomer, offers appreciable everyday flexibility: the Parsec bends without excessive resistance and does not retain the memory of its curves.

Termination and finish

Neutrik XLR connectors equip the standard version. Cardas also offers its own CG XLR connectors as an option. Each cable is terminated by hand in the Bandon, Oregon workshop by a team of specialized technicians. This American manufacturing comes with a lifetime warranty.

With an outer diameter of 9.14 mm and a gauge of 2 × 23.5 AWG, the Parsec remains a manageable cable, easy to route behind a rack without excessive bulk.

What sonic signature can you expect?

The Parsec retains the full-bodied midrange and rich harmonics that characterize the Cardas sound. The difference from the Quadlink is in the transparency and definition of the soundstage: layers are better separated, transients are sharper, and the bass is more responsive. The reproduction leans slightly toward the warm side of the spectrum without tipping into softness.

This character will suit systems that lack body or whose highs tend toward the analytical. On an already warm setup, the Parsec may accentuate this tendency.
