Mundorf MCap Evo Alu 270 µF 250/170 VDC/VAC capacitor
MCap Evo Alu

ME-270T3.250

The MCap Evo Alu brings the system into a state of controlled serenity. Voices become clearer and calmer without becoming brighter. The soundstage gains focus while remaining relaxed and effortless. Even at higher volumes, everything remains orderly, confident, and relaxed, with clearly audible fine details. The MCap Evo Alu is the gateway to the world of high-end capacitors, a world full of dynamics, precision, and timbres.

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

Silver-Gold Metallization (Ag-Au)

Gold stabilizes interfaces, smooths out microspectrum, adds color to silver.

Silver – Gold Metallization (Ag – Au)

The Silver-Gold Metallization combines the maximum conductivity of silver with the interfacial stability of gold. Silver provides precise, finely resolved signal routing with very low noise; gold stabilizes grain boundaries, slows down diffusion and smooths the microspectrum — particularly with small signals and over a long period of time.

Tonal effects

  • Finer texture and more stable reproduction of the smallest details (overtones, spatial fractions, fading processes)
  • Richer, differentiated timbres with a clear outline — colorful but ordered
  • Quieter, more “mature” overall impression: less nervousness, high long-term suitability
  • Noticeably more heart, rhythm and joy of playing with insight and precision

Vacuum Oil Impregnation

Oil penetrates every pore, stabilizes the wrap, reduces macro-microphony.

Vacuum Oil Impregnation

Vacuum oil impregnation involves displacing air from the coil and drawing a special oil — whose dielectric and hydromechanical properties optimize the desired acoustic characteristics of the coil structure — into every pore under a vacuum. The oil wets film and paper surfaces, stabilizes the wrap from the inside and dampens extensive movements — macro microphony is reduced deep in the wrap structure. In this way, the capacitor remains mechanically quiet even with high pulses and dynamics and does not falsify the music signal through its own movements.

Tonal effects

  • Reverb decays, fading processes and quiet room information are more prominent because the wrap inside is calmed down
  • Even with high dynamics, the sound remains calm and orderly; loud passages do not drown out the quieter details
  • Transients (blowing noises, string strokes, cymbal impulses) come precisely, completely and without sharpness
  • Overall impression: relaxed, controlled and at the same time exceptionally detailed

Evo Wrapping Geometry

Lowers ESL and ESR, significantly improves timing, focus and audibility.

Evo Winding Geometry

The Evo winding geometry uses many narrow turns of the electrode foils, with end-face contacts, instead of a few wide layers. As a result, current paths are shortened and the power distribution over the entire winding surface is significantly more homogeneous. This not only significantly lowers the equivalent series inductance (ESL), but also the equivalent series resistance (ESR) — the capacitor processes transients faster, in a more controlled manner and at the same time remains mechanically more stable and less susceptible to mechanical resonances. The result is a precise, focused and stress-free listening experience that remains organized even with complex music.

Tonal effects

  • more precise transients and clear rhythmic structure
  • More stable center, clearer localisation and a more focused soundstage
  • better transparency in dense, complex music
  • more control and sovereignty even at higher levels
  • stress-free precision without nervousness
  • clean microdetails without temporal smearing

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

Learn more
Reinforced Metallization

Reduces electrode resistance, reduces hot spots, keeps parameters stable under load.

Reinforced Metallization

Reinforced metallization means a deliberately thicker metal layer on the insulation film. As a result, the resistance of the electrode tracks drops significantly, conductivity increases, voltage drops and local heating are reduced, and field gradients are flattened. The capacitor remains stable under pulses and high current peaks because the electrode does not become a limiting factor: energy is available more quickly and in a more controlled manner, capacity and losses remain more constant even under load, and signal-related modulations in the metal grid are reduced. The result is superior, powerful and clean transmission behavior — even if it becomes dynamic.

Tonal effects

  • controlled, powerful and clear even at peak levels
  • Bass and drum impulses with more authority and drawing
  • more stable sound without electrode-side “flickering”
  • more peace and order in complex, dynamic passages

Encapsulation in Housing

Fixes the wrap, dampens resonances, prevents signal-related oscillation.

Encapsulation in a housing with visco-elastic sealing compound

Encapsulation in a housing with visco-elastic sealing compound means: The capacitor wrap is mechanically calmed and permanently fixed in the fixed housing — not only against external vibrations, but also against stimulation from the music signal itself. This is because alternating current generates field forces that can set the winding in motion; this is precisely what causes macro-microphonic feedback when the capacitor winding resonates. The encapsulation prevents this feedback from building up: coupled energy is absorbed by the viscoelastic layer, resonances are widely dispersed and their amplitude is reduced – resonance peaks are effectively eliminated.

Tonal effects

  • Stable, relaxed stage even at high levels — the capacitor remains “silent”
  • Clear location: Voices and instruments retain their shape and position
  • Less housing noise and structure-borne noise — the sound appears sorted and focused
  • More audibility: quiet room information and fine details are retained even when dynamic

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
