Tin plating
A Supra concept for cleaner sound. The tin is of higher resistance than copper and also protects copper from bad sounding corrosion. It also mini-mises the current jumps from wire to wire over corroded copper sur-faces while more of the signal passes through the pure copper inside the wires. The tin layer also minimises the skin-effect, by acting as a semi-Litz.

Silver plating
Only when the frequen-cies are very high, as in digital signals, does it seem wise to go the opposite way, i.e. to silver plate for a lower surface resistance. At such high frequencies it is hard to keep the signal inside the wire, so instead we design for an easier surface current flow.

Digital interlinks
Important properties of digital cables are a high propagation velocity factor and a correct and stable characteristic impedance (Z).

Analogue interconnects
Low capacitance (C) is important.

Microphone- and line cables
Low microphonic effect, and low capacitance assist quality.

Loudspeaker cables
Loudspeaker cables generally need to be of low inductance (L) and preferably also of low resistance (R).
