VSF Pure Foil Caps

About the VSF Pure Foil Caps

The Duelund VSF (Virtual Stack Foil) Pure Foil Capacitors are crafted for audiophile loudspeaker crossover applications. They consist of pure aluminium, copper, or silver foil combined with high-density paper soaked in pure mineral wax and treated with natural lacquers, then wrapped in paper, making them environmentally friendly. The design emphasizes flatness and stacking of foil layers to achieve very low inductance and eliminate internal resonances, resulting in exceptional sonic naturalness, clarity, and spatialization. They are handmade with ultra-low tolerances and offer a natural sound signature characterized by immediacy, harmonic authenticity, and detail. The lead connected to the outer foil is marked with a 'D' on the capacitor and should be connected to the signal output. The VSF range is rated up to 200 VDC for speaker use, with copper, aluminium, and silver foil variants, though some versions like silver and aluminium are discontinued. These capacitors are highly regarded for their natural sound and are considered among the best for crossover applications. The VSF Pure Foil Caps have a wax/paper dielectric and are impregnated with mineral wax, contributing to their tonal qualities and mechanical stability.
