Long-term listening impressions: Duelund "Dual" DCA16GA Interconnects with Duelund Plastic-Free RCAs.

It has been almost exactly a year and two months ago that Frederik sent me a pair of the then newly released Duelund "Dual" DCA16GA interconnects with Duelund plastic-free RCAs to listen to (HERE).   The time has gone by so fast it is almost frightening! With more than a year of listening to them under... Read More »

Jeff checking in: Audio Note (UK), Duelund, Leben HiFi Stereo Company, Pass Labs, Sophia Electric, and other stuff!

I just finished up the feature review of the Leben HiFi Stereo Company CS-600X vacuum tube integrated amplifier for Positive Feedback, which you can read HERE.  Like the CS-600 integrated amp that preceded it, the CS-600X is a terrific moderately powerful integrated amplifier, with 32W from 6L6GC output tubes, and 28W from EL34 output tubes. ...

Updating my vintage Altec 832A Corona based system with the new Duelund 600V DCA16GA tinned-copper wire!

There's been some big changes in my vintage Altec 832A Corona based bedroom system recently.

Today's Fresh Catch: The New 600V Duelund DCA16GA Tinned-Copper Wire!

I always love a mystery, and when a mysterious box appears from Frederik Carøe (Duelund Coherent Audio) I get intrigued real quick!

The Duelund-Altec Project: Breadboarding the Duelund CAST Sn-Cu Crossovers!

Originally I had planned on building external crossovers for the vintage Stokowski Altec's on the beautifully made Hammond HWCHAS Series Heavy Duty Walnut Chassis With Aluminum Top (HERE). I thought the Hammond's aluminum top plate painted in Altec green like the 511-B horns would make for an attractive nod to Altec tradition. However, the large... Read More »

The Duelund CAST Carbon/Sn-Cu Resistor: The "Jeffistor" makes its debut!

I really want to thank Frederik Carøe for being so generous as to indulge a resistor idea of mine, and then going way beyond what I imagined to handcraft a truly amazing resistor, which Frederik has humorously dubbed the "Jeffistor". The idea behind this resistor was a result of my listening impressions while doing trials with... Read More »

After my buddy Chad helped me move the big Stokowski Altec's into the position normally occupied by my Westminster Royal SE's last weekend (thanks Chad!), we did a fair amount of listening, mostly to a lot of classic rock (Chad's fave), but also some jazz.

The Duelund-Altec Project is about to get under way - the adventure begins!

It's almost time for the Duelund-Altec Project to get under way!
