Mundorf MCap Classic 400V 8.2 µF 400/275 VDC/VAC capacitor
MCap Classic 400V

MCAP400-8,2

The MCap 400 series features a thicker foil and a larger winding, which mechanically stabilizes the capacitor and reduces Macro-Microphony effects. This noticeably improves playback precision compared to the MCap 250.

Technologies

Aluminium Metallization

Reduces charge carrier dispersion at grain boundaries in the metal, reduces sound roughness, calms the noise spectrum.

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

Pure aluminum metallization replaces the zinc-aluminum mixture commonly used in industry with a homogeneous metal structure. This reduces interface effects at the grain boundaries , stabilizes the conductivity across the electrode surface and results in a significantly quieter noise spectrum. For example, the basic design of an MCap is audibly different from typical industrial capacitors.

Tonal Effects

  • Darker, quieter background — subtle artifacts recede
  • Clearer, clearer stage without rough-metallic side effects
  • Quiet, well-defined overall sound — a real introduction to audiophile quality

Optimized Winding Tension & Stabilization

Soothes the wrap, reduces macro microphones, increases silence and location precision.

Optimized Winding Tension plus Stabilization

Optimized winding tension and additional stabilization mechanically calm the wrap and significantly reduce macro-microphone effects — for a quieter background, a more stable stage and clean transients, even with dynamic music and higher levels.

Tonal effects

  • more peace and order in the sound image
  • More precise positioning and a more stable stage
  • clearer microdetails without smudging

Tight Tolerances

Make sure that the left and right channels work identically, important for stable stage and positioning.

Tight Tolerances

Tight tolerances in capacitance, inductance, and resistance ensure that capacitors of one type are very close together in terms of their electrical properties. In crossovers, the left and right channels therefore work virtually identically: crossover frequencies, level ratios and phase positions match closely. This is the basis for stable, precise stereo imaging and reproducible results — in series production and also after service.

Tonal Effects

  • precise, stable soundstage without drifting
  • Coherent overall impression: left and right channels fuse into a single, seamless whole
  • characteristic sound is reliably retained even after component replacement/repair
  • More stable virtual center and clearer spatial layering
