In my first post about my very preliminary first listening impressions of the Duelund DCA12GA tinned-copper tone wire speaker cables, that I had just cut cold off the roll, I told you how the DCA12GA as speaker cables on my Westminster’s were warmer & richer sounding than the my usual bi-wire Duelund DCA16GA/DA20GA speaker cables, which I liked a lot.

Cowboy Junkies’ The Trinity Session.

I also thought that the sibilance region for horns and voices sounded more natural with the DCA12GA, and that the DCA12GA had good measures of that familiar vividness, beautiful tone color, and timbral ‘realness’ that I love about tinned-copper conductors.

I had a few nits to pick with the DCA12GA cold off the roll though, as I thought that with the DCA12GA there was a slight ‘dryness’ to the vocals on the Cowboy Junkies’ The Trinity Session LP that I hadn’t noticed with my bi-wired DCA16GA/DCA20GA speaker cables, and that there were occasional instances of stridency as well.

Duelund DCA12GA interconnects!

I liked what I was hearing so much with the Duelund DCA12GA as speaker cables, that I built a pair of interconnects out of the fat Duelund DCA12GA tinned-copper wire too.

That’s not what one does with interconnects normally, because skinnier gauge wires are de rigueur for interconnects, and it takes some work to accommodate the tubby DCA12GA within the RCA’s, but more about the DCA12GA interconnects later.

I also mentioned that I had cut a second set of Duelund DCA12GA to use for speaker cables that I was going to put on my Cable Cooker for a few days to get a better idea of what a set of run-in DCA12GA sounds like.

Cooked DCA12GA speaker cables.

The extra set of DCA12GA speaker cables have been cooking away for four days now, so I pulled them off the cooker and put them into the system in place of the uncooked DCA12GA speaker cables, and gave them a listen with The Sergio Mendes Trio’s Brasil ’65 LP.

I noticed right away that while they maintained their warm and rich presentation, they also had opened up quite a lot to sound more spacious and articulate, with more low level detail emerging.

The vividness, tone color, and timbral ‘realness’ that I heard from the DCA12GA with no run-in time, sounded similar, but perhaps subtly improved.

I also noticed right away that the cooked DCA12GA had a more convincing portrayal of tempos, so that was a definite plus as well.

The nits I had to pick, the vocal dryness and occasional hints of stridency, didn’t show up at all on Brasil ’65 LP as I listened to it.

I put back on Cowboy Junkies’ The Trinity Session LP that I heard the vocal dryness and occasional hints of stridency on, and I thought that those qualities were still there, but in reduced amounts on the cooked DCA12GA.

I should point out that I still have the uncooked DCA12GA interconnects in the system, so that may be contributing to the nits.

So the plan now is to put the uncooked DCA12GA speaker cables onto the Cooker, along with the DCA12GA interconnects, and cook them for a while to hear what happens.

I think that with the bigger DCA12GA, they may need more time on the cooker to fully run-in, so I’m going to cook them for a full week.

I’ll report back on the results of that cooking session in about a week, so please wait for it! 🙂


As always, thanks for stopping by!

  1. Hi Jef, that’s very reassuring, as my DCA12GA just arrived yesterday afternoon. I put it on my DIY cooker (just an old portable CD player system with 8 Ohm resistors in series with the wire), and I’ll let it run for a while before I hook it up. Fingers crossed!

    Best regards,

    • Hi Richard,

      I predict you’ll find the DCA12GA an enjoyable experience!

      Keep me posted on your impressions as you get some more time on them.

      Kind regards,


  2. I just finished installing my DCA12GA on my front speakers in my AV system to break in and are listening to them as I write this .. they replaced some Mogami 3103. Cold & not cooked, I am really impressed with the major difference. Sounds like lots of ‘audio gold’ to be mined yet. Thanks so much to all for your good input !

    • Dear Burphardt,

      Thank you so much for the kind words, appreciated!

      I really like the DCA12GA too, and keep me posted on your results as you get some more time on them!

      Kind regards,


  3. Tell Jeff, which Duelund (DCA12,16,20GA) is best for connecting the speakers inside?

    • Hi Chris,

      I haven’t really tried that yet, as it’s a big job with the Westminster’s, and I’m thinking about how best to go about it.

      For the low-frequency wiring I’m thinking the DCA12GA could be pretty nice, but the DCA16GA is a possibility too. For my high-frequency wiring I’m thinking of the DCA20GA, or possibly the Duelund silk/silver 1.0 or 2.0.

      I have a couple of more Duelund wiring trials I want to do with my Duelund outboard crossovers, and then I’ll have a better idea what I want to put inside the West’s.

      When I get it all figured out, I want to write a feature article for Positive Feedback about rewiring my entire WRSE system with the Duelund wire, and discuss the different voicing options that the different wires offer.

      It sure has been fun giving the different Duelund wires a try in my system!

      Kind regards,


  4. used a duelund silk 1.0 flat silver for high tones of Tannoy Gold Dual concentric and I have to say it fell out of favor. The sound made flat, stiff without emotion without music without plans. Everything came back to life after connecting dca12ga duelund.
    Not always what silver and expensive must be better

    • Hi Chris,

      It’s not always easy to tell what wire will work best for a particular application. Right now I’m using shielded Duelund DCA16GA IC’s from my Intact Audio SUT to my MX110Z pre, and Duelund Silver 1.0 from the Aria Lab SUT to my MX110Z pre, and both are good matches to those cartridge SUT combinations. I’ve got the Duelund DCA20GA as interconnects from the MX110Z to my MC30 monaural amplifiers, and DCA12GA speaker cables from my amps to my WRSE’s crossovers. Internally in my crossovers I’m using DCA16GA for the LF circuits and DC20GA for the HF circuits, but I intend to play with that little more not that I have the DCA12GA here.

      I’ll also be curious about the new solid-core tinned-copper DCA26GA that will be coming out in the near future, and there’s a couple of applications I want to try that in.

      I’ve not been considering the cost of what goes where, just the musicality & sonics, and it seems as if there is a nice match for each part of the signal chain in my system, which gives a lot of flexibility in voicing.



  5. My speakers are three way active. Would going with 12 Ga on the woofers, 14 on the mods and 16 on the tweeters make sense?
