We hope you’ll join us at, we will use the blog to compliment this news board.


See you at the Rocky Mountain Audio Fest 2009. Kaiser Acoustics kindly filled their Kawero! loudspeaker to the brim with all kinds of Duelund goodness.

Come say hi, Marriott 4th Floor ~ 445. We promise to be there.


September 2009:

We are nearing the launch of our new CAST resistor. Looking forward to tell you more.


August 2009:

A nicely done review of top of the line signal capacitors has been published by Jimmy Auw at Jimmy’s Junkyard. (Apparently our CAST 630v came out on top…)

July 2009:

We advise that you check out the interesting feature done by Mr. Clement Perry of on the Kaiser Kawero loudspeaker in its creator’s lair:


All filter functions in the Kaiser Kawero are handled by Duelund components.


June 2009:

A recent shuffling of the cards chez Humblehomemadehifi has graded our CAST capacitor even higher, further emphazising its lead as the capacitor of choice for true enthusiasts.

We are glad to see the strive for natural sound is so highly rewarded.



For years we’ve been a part of Natural Sound of Argentina’s chosen products. Recently, they launched their new speaker, emphatically christened Big Bang B.

We can attest to the ultra high quality of the speaker’s innards, and have on good authority that the sound is nothing short of magical.

Mr. Scarafiocca of Natural Sound would accept nothing less:

May 2009:

Just a quick snapshot of a prototype midrange filter from Peak Consult:

In case you’re wondering, that’s quite a few µFs…


It’s always a pleasure when companies firmly rooted in the ultimate part of audio choose your components for their reference product having tested all brands available.

Perfect8 Technologies will be using our silver/carbon resistors and full CAST line of capacitors and inductors, in copper as well as silver for their superlative offerings.

These very talented individuals have received endless acclaim, we advise you follow them closely. Apparently, the word transparency describes the enclosure and sound in equal terms.

We’re proud to announce we’re strengthening our base in Sweden:

Audio specialist Accurate Audio has recently begun carrying our full line of products.

March 2009:

For an unusually intelligent comment on the current state of our hobby, may I suggest visiting this site run by Mr. Flemming E. Rasmussen of Gryphon Audio Designs, an old friend of ours. (The term old is used to describe the number of years, we’ve been acquinted, not the age of the man himself. We wouldn’t dare….)

IMHO it’s a great read.


We are pleased to announce Duelund Coherent Audio now features representation in Poland:

We suggest you visit this amicable setup:


ul. Rzeznicka 12H

tel. +48 501 173793, +48 58 6779192
fax. +48 58 6774036



The unstoppable guys of have created a great little tool, which allows you to calculate target curves for the Duelund Synchronous filter.

We advise you check it out:



We’ve been allowed to show you a picture of the first working Dragon of the Peak Consult Momentum line. Peak Consult will introduce the Momentum upgrade on various loudspeakers in their line, but today we show you the Dragon Momentum.


From Duelund the speaker features an all out Duelund filter including giant midrange capacitors and a very special CAST MOMENTUM-DEKA cap.

The MOMENTUM-DEKA uses 10 capacitors in one cap to achieve the desired value. To top things off, it is then CASTed to prevent any unwanted resonances.

The end result according to Mr. Per Kristoffersen Head Designer at Peak Consult is: “Unlike anything I have ever heard let alone dreamt possible!”

We’re quite pleased as well.

February 2009:


Electrum Audio one of our very first dealers recently concluded their painstaking work creating their new home on the web, complete with all Duelund products and online ordering we deem it to be of very high quality and hope you do to. Please check it out at:

Mr. Mike Tehan of Electrum Audio was a driving force in creating the Duelund VSF DC and CAST 630v caps for electronics, so rest assured you are in good hands!



Our apologies for the blatant misuse of the caps lock key, but when you are judged against nearly 50 other capacitors and come out as the true number 1, the sound of Ode to Joy seems to echo in your ears…

Some years ago the talented and skillful DIY’ing Dutchman Mr. Tony Gee of tested our Virtual Stack Foil Cu capacitor and came to the natural conclusion that it was the best sounding capacitor available.

As time flew by, many challengers vied for the throne but were denied. The VSF remained supreme.

Realising that something had to be done about this, we send a pair of Duelund Coherent Audio CAST capacitors to set the record straight.

We are proud to announce the following result:

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 (especailly 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!

Following our field trip into the heart of the South Korean High End community a little teaser seems apropos.

In the aftermath of the highly successful launch of their Dragon flagship loudspeaker Peak Consult has created a special model entitled The Dragon Momentum.

While details remain sketchy at this time I can reveal that the Momentum will contain a world’s first from us at Duelund. Details will be posted when the speaker is officially launched.

Untill then:


Around the world…

Our distributor in South Korea Mr. Hoyoun Kim of Sonoris had cordially invited us to attend the Asian launch of Peak Consult’s flagship speaker The Dragon in Seoul. Seeing as Peak Consult features exclusive Duelund components in the filter of The Dragon we were only happy to attend. The sound of the Dragons driven by Soulution electronics fed by the Kuzma XL turntable was little short of miraculous.

November 2008:

Back from Rocky Mountains show in Denver, a big thank you to everybody we met there, hope you had a great show. We certainly did.

Honourable mention to our friends from Kaiser Akustik who launched their Kawero loudspeaker to great acclaim (to many Sound of the show).

Since the poor guys were setting up a very large room, we had (unwisely…) promised to help with the setup of the speakers. The Kaiser guys deemed it only fair that I lifted the bottom of the speakers, since the (quite heavy) Duelund filter is located there…

Apparently, they didn’t think Mr. Radisaljevic from Raal Ribbon, should lift the top with the famed Raal Ribbon tweeter.

Suffice it to say: I couldn’t move my right shoulder for the rest of the show…
