Evo Winding Geometry

The Evo winding geometry uses many narrow windings of the electrode foils with end-face contacts instead of fewer wide layers. As a result, current paths are shortened and the power distribution across the winding surface is significantly more homogeneous. The many windings connected in parallel behave electrically like a bundle of small, very well-coupled current paths : The capacitor reacts faster, more evenly and in a more controlled manner.

A key result of this architecture is a significantly reduced equivalent series inductance (ESL) — but not only that: The shortened current paths and parallel current supply also significantly reduces the equivalent series resistance (ESR). This means less voltage drop across the component under load, less loss-related heating and more stable parameters during pulse spikes. Especially in audio applications, where rapid current rises, complex pulse sequences, and high dynamic range occur, this combination of low ESL and low ESR is crucial: The capacitor remains “fast” and “powerful” at the same time—precise without softening the sound, and stable without becoming erratic.

In addition to electrical properties, Evo geometry also has a mechanical effect: The fine segmentation increases the stability of the wrap, reduces sensitivity to vibrational stimuli and reduces the tendency for annoying eigenmodes. The wrap behaves less like a large, resonant surface, but like many smaller, mechanically controlled units. This not only makes the capacitor electrically cleaner, but also macro-microphonically quieter — an important factor for an orderly, stress-free sound.

This design significantly increases production costs: More windings have to be wound, the operating times on the production machines increase, the end surfaces become larger and the cost of metallization and foil material increases. However, this additional investment in production time and material is more than justified by the electrical and sonic results — because it has a direct impact on what really matters in audio: transient response, rhythmic precision, soundstage stability, and the ability to reproduce even complex musical signals in a controlled and effortless manner.

Tonal Effects

  • Impulses are clearly defined and reproduced with precise timing; attacks and transient processes appear more defined.
  • Rhythmic structures remain comprehensible even with complex grooves; microdynamics and subtle accents “hit the mark”.
  • The soundstage gains focus and localisation precision, particularly in the center — voices “stand“ reliably in the center.
  • Greater transparency in dense music: Individual events remain distinct without the soundstage falling apart.
  • The presentation remains stress-free: high precision without nervousness, no harshness caused by instability in charge carrier transport.
  • Bass and fundamental frequency impulses are more controlled because the lower ESR guides the energy flow more cleanly (depending on circuit/position).
