Tinned Copper CAST Capacitors

About the Tinned Copper CAST Capacitors

The Duelund Coherent Audio Tinned Copper CAST Capacitors are part of Duelund's flagship CAST series, designed for audiophile-grade audio applications such as crossover networks, signal coupling, bypassing, and filtering. These capacitors use tinned copper foil as the conductive material, separated by paper impregnated with a proprietary WPIO dielectricum under high pressure and vacuum conditions. This manufacturing process provides exceptional damping properties and mechanical stability, minimizing losses, distortions, and microphonics. The capacitors are rated at 630V DC with a 2% capacitance tolerance and feature twisted tinned copper leadouts for optimal electrical performance. Each capacitor is handmade in Denmark using a labor-intensive process that emphasizes natural materials and resonance control, resulting in a large, heavy component that delivers a natural, uncolored sound with enhanced clarity, dynamics, and spatial resolution. They are highly regarded by audiophiles and professionals worldwide for their exceptional craftsmanship and sonic transparency.
