World’s best capacitor…

The Duelund CAST Capacitor is our no holds barred flagship capacitor.

The construction builds on the foundation of our Virtual Stack Foil design but does so with the addition of a proprietary WPIO dielectricum which necessitates several days of impregnation under high pressure.

This creates a form with incredible damping properties giving a mechanical stability hitherto unheard of.

On top of this casting process, a ring of hard pressed paper strengthens the damping properties of the design helping music flow effortlessly.

The Duelund CAST capacitor is available for speaker use and as the CAST 630v for DC-applications for size considerations this cap is cylindrical.

Available as pure copper or copper/silver.

Standard sizes 0.001 uF – 50 uF other values available on request.

The Duelund CAST Capacitor is considered the world’s best capacitor:

Sound: The CAST capacitor has all the same characteristics as the VSF but with added top-end clarity and together with that, more spatiality. They are (like the VSF) super natural, smooth, clear and open. The tonal balance is extremely neutral, especially audible with good recordings of acoustic instruments and the human voice, so maily with classical music. Like the VSF the separation of the individual instruments is very good and in an orchestra, the string section is a group of individuals rather than just a group. Soprano’s have clarity without becoming hard to the ear, wind instruments (especially the copper section) have that nice “metal” edge without becoming rough. Where in the past you had to choose between a Mundorf Silver/Gold/Oil (very good depth and imaging) or a Duelund VSF (very neutral presentation) you can now have the best of both worlds in the form of the Duelund CAST-Cu. I did find they needed a couple of weeks use to fully come to bloom, so give a chance to burn-in. My current reference!

So in other words: The king is dead, long live the king!
