The vacuum-assisted impregnation of the winding with – a special oil whose dielectric and hydromechanical properties optimize the sonically beneficial characteristics of the winding structure – stabilizes and dampens the structure deep into its core and utilizes the macro-microphonic potential to calm the component almost entirely. The MCap Evo Alu Oil sounds clean and very quiet. Voices come across as relaxed and clearly focused, with subtle spatial details emerging from a dark, orderly background. The soundstage remains stable and transparent during complex and loud passages; microtextures such as breath sounds, fine transients, and nuanced overtone spectra become clearly audible – making the MCap Evo Alu Oil an ideal partner for long-term, high-quality musical reproduction.
