Mundorf MCap EVO Oil capacitor combines the MCap EVO's sound characteristic with the acoustical advantages of oil impregnated capacitors.
Mundorf MCap EVO capacitors (EVOLUTION winding technology) come with an unusual narrow but high capacitior reel. This geometry results in a short but utmost little loss signal path betwen huge contact areas. The MCap EVO is a polypropylene capacitor with little tolerances +/- 3% (values above 100 uF: 5%)
Mundorf MCap EVO Silver Gold oil capacitor unites the audible feature of the MCap EVO oil with those of a Silver Gold metallization. It does not have the winding technology of the Supreme capacitors, making it an inexpensive entry into the Silver/Gold capacitor world.
