CablePhile 7 series interconnect cable C7A is the secondary flagship in all the interconnect cable. It's composed of the Ultra Pure OCC conductor which spiral wrapping on one piece insulated sliver plated OCC conductor,triple stable insulation materials, dual metal shielding materials, red cooper terminal which plated gold directly,cold-welded, accurate CNC and did strict anti-oxidation treatment. It is totally good at the consistency,physical structure, none chemical aging, none mechanical aging and greater absorption of RF/EMI. The performance of C7A is super high frequency extension, amazing linearity, nature, also super low noise floor.
