The 1st gen of silver-shielded cable was applied to the Nyx 09 series. It uses a relatively complex structure with separate shielding for its power supply and data transmission, which is of great help to devices that are susceptible to interference in the power supply. The Nyx 07 series uses the 2nd gen of silver shielded cable, which arranges the power supply and data conductors at equal intervals. It also uses imported insulation material and adjusted the density of the shielding grid, black-and-white spacing and outer-layer insulation to match the impedance.
