Aluminum metallization (100% aluminum instead of zinc-aluminum mixture)

Zinc-aluminum metallizations are used in many industrial AC capacitors: process-safe and cost-effective, but with higher interfacial activity (grain boundaries) in the metal grid and rougher noise behavior. In audio mode, these subtle, material-specific effects can be felt as additional unrest — not necessarily as an “error” that is noticeable in the data sheet, but as a subtle veil, as a roughness, or as a slightly metallic aftersound in the background.

Pure aluminum metallization contrasts this with a homogeneous metal structure. It ensures more stable conductivity over the surface and a quieter noise spectrum. As a result, the basic design of the component is brought much closer to what we mean by a real audio signal capacitor: fewer proprietary artifacts, more silence, more clarity. This is precisely where the core of an MCap differs from typical industrial capacitors — not because of a single “marketing feature,” but through a conscious material technology decision with clear acoustic consequences.

Tonal Effects

• Background noise and subtle background artifacts are reduced; the background appears darker and quieter.
• The stage opens up clearly and clearly, without being overshadowed by rough, metallic-looking side effects.
• The overall character is calm and well-defined — the entry into the class of audiophile components.
