Duelund Coherent Audio – We’re thrilled to share some news for the high-end audio community: work is well underway on the new Duelund JDM Alu-WPIO (Aluminum Foil, Wax-Impregnated Paper In Oil) Capacitor Line, designed to carry forward — and elevate — the legacy of the original Jensen aluminum foil paper-in-oil capacitors.

When Jensen, whose capacitors set a high bar for natural tonality and musicality, ceased production, a void was left for discerning audiophiles and builders alike. Duelund, renowned for uncompromising craftsmanship and sonic purity, has taken up the challenge. Drawing inspiration from the best of the Jensen designs but improving key areas like materials sourcing, foil purity, and construction methods, Duelund’s JDM Alu-WPIO aims not just to replace but surpass the performance of the classics.
Expect the hallmark rich, organic midrange, sweet treble, and beautifully textured bass that paper-in-oil designs are known for — but with even greater refinement, stability, and musical flow, thanks to Duelund’s no-compromise approach. Early prototypes have been highly promising, and full production is expected soon.
Whether you’re restoring vintage gear, crafting a new reference preamp, or upgrading your loudspeakers, the Duelund JDM Alu-WPIO capacitors are shaping up to become the new gold standard for those who crave authentic musical engagement.
Stay tuned for more updates — the future of wax and oil-impregnated audio capacitors looks brighter (and more beautiful) than ever!
