CAST capacitors



The Duelund CAST Capacitor is the no holds barred flagship capacitor. The construction builds on the foundation of the Virtual Stack Foil design but does so with the addition of a proprietary WPIO dielectricum which necessitates several days of impregnation under high pressure.

The Duelund CAST capacitor is available for speaker use and as the Duelund CAST DC for higher voltage applications.

We concentrate primarily on parts used inside tube amplifiers. For this reason we stock the high voltage, low capacitance capacitors. However we can supply all values and all versions of the Duelund capacitors.




Duelund CAST Capacitors



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 DC for up to
630V DC-applications. Available as pure copper or pure silver.

The Duelund CAST capacitors are designed for speaker use.
They are rated up to 200 Volts DC and are available in:
Copper - CAST CU (0.1uF to 40uF)
Silver - CAST AG (0.1uF to 8.2uF) please ask for a quote for values above this range.

The Duelund CAST DC capacitors are for signal applications in amplifiers and
pre-amplifiers.
They are rated at 630 Volts DC and are available in:
Copper - CAST DC CU (0.22uF to 2.2uF)
Silver - CAST DC AG (0.1uF to 2.2uF) please ask for a quote for values above this range.




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 mainly 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!
