CablePhile 5 series interconnect cable C5A design for the high level audio component systems. It is composed of the 4 in 1 dual spiraling Ultra Pure OCC conductor, triple stable insulation materials, anti-corrosion metal shielding materials and the red cooper terminal which plated 30 um sliver directly, cold-welded, accurate CNC and also did strict anti-oxidation treatment. It is totally good at the consistency, physical structure, and none chemical aging, none mechanical aging,greater absorption of RF/EMI. The performance of the C5A is high frequency extension,impressively low noise floor, better linearity, emotional.
