Copper Metallization (Cu)

After silver, copper is one of the most conductive materials in use and offers a balanced combination of electrical conductivity and mechanical stability. Copper metallization allows high current-carrying capacity with easily controllable behavior — a material that not only “conducts well,” but also remains robust and stable in real operation. Interfaces and transitions behave differently than with aluminum. It is precisely these differences that shape an independent electrical and micro-microphonic profile, which can become tonally relevant, particularly in the basic and midrange ranges.

In an audio context, this means that copper does not simply add “more” of something, but changes the way sound colors, body and base tone energy appear in the overall musical picture. Voices and acoustic instruments particularly benefit from this characteristic, because the perception of naturalness and “humanity” depends heavily on the interplay of basic tones, overtones and inner peace. Copper can support this balance in a very musical way — without shifting the sound image towards dullness.

Tonal effects

• The sound gains body and warmth, particularly in the base and midrange.
• Voices and acoustic instruments appear more natural, familiar and “human” without losing too much of their drawing.
• The playback invites you to listen for a long time, relaxed, because it looks more “like in a concert hall“.
