Duelund VSF Copper Capacitor - 100VDC – 2% tolerance

Duelund VSF Copper Capacitor - 100VDC – 2% tolerance

Technical Specifications (according to manufacturer): “The Virtual stack foil capacitor, a capacitor made specially for loudspeaker crossovers. This new capacitor is the realisation of a lifelong ambition. It consists of copper foil and high-density paper, soaked in pure mineral wax, coated with pure cocoon silk and finally, treated with special lacquers made from natural materials. It is without question a "green" product. The actual construction has been overseen by Mr. Steen Duelund Chief Engineer of Duelund Coherent Audio. Mr. Duelund has dictated the capacitor's special characteristics, i.e. its flatness, giving the opportunity to create its stack-foil working manner ensuring very low inductance, forming a solid block resulting in a form free of internal resonance. Furthermore, the flatness makes it easier to achieve greater values by connecting the capacitors in parallel”.

Sound: WOW! Now I know how natural a capacitor can sound! They are super natural, smooth, clear, open, and at the same time they stay calm and controlled but delivering dynamics when the music calls for it. The tonal balance is near perfection, especially audible on acoustic instruments and the human voice. This makes my classical music collection so much more realistic. Also I was very pleased with the separation of every individual instrument in an orchestra, the string section is much more a group of individuals rather than just a group. In comparison I found the Mundorf Silver/Gold to be a little over-etched sometimes, they seem to have a slight top-end emphasis. The Duelund VSF Copper Capacitor seems to be the only capacitor I have tested so far that doesn’t need bypassing with an MKP1837 to be at its best.

Verdict: 12,5
