Which is better? The Duelund DCA16GA, Duelund DCA20GA, or the Duelund Silver/Silk interconnects?

The conclusion that I’ve come to is that they all are better, depending upon the application I’m using them for.

For example, I had been using a set of nude Duelund DCA16GA interconnects to connect my vintage McIntosh MX110Z tuner-preamplifier and vintage McIntosh MC30 monaural amplifiers, and was liking the results.

I then tried the Duelund 1.0 silver/silk interconnects terminated with Duelund Rhodium RCA’s that Chris at Parts ConneXion built up for me, but they sounded too laid back and blah between my vintage Mac’s, so out they came and the Duelund DCA16GA tinned-copper interconnects went back into the system.

Then the Duelund DCA20GA tinned-copper tone-wire arrived, and I built a pair of interconnects so I could compare them to the DCA16GA interconnects between my Mac’s.

When I connected my MX110Z & MC30’s with the Duelund DCA20GA interconnects, I really liked what I was hearing.

The sound was even more balanced top-to-bottom, smooth, articulate, nuanced, and very naturally ‘real’ sounding, and I was immediately smitten with the results! Wow!

I was on a roll, so I decided I’d build up a pair of shielded DCA20GA interconnects to try between the Auditorium 23 SUT and MX110Z, for use with the Sumile phono cartridge that’s in for review.

It turns out that the shielded DCA20GA interconnects didn’t perform nearly as well with the A23 SUT to MX110Z connection as I’d hoped, and they certainly weren’t as brilliantly musical as the nude DCA20GA’s were between the MX110Z and MC30’s.

Then I tried the shielded Duelund 1.0 silver/silk interconnects terminated with Duelund Rhodium RCA’s that Chris at Parts ConneXion built up for me, to connect the A23 SUT and MX110Z, and it was a match made in heaven for use with the Sumile phono cartridge!

The same sort of thing happened with the very nice Belden 8402 microphone cable interconnects that I was using between my Intact Audio SUT’s that I use with my Ortofon SPU Classic GM MkII.

When I tried the shielded DCA16GA interconnects that Chris at Parts ConneXion made up for me, they were incredibly musical & engaging on the Intact Audio SUT’s, with great presence and vivid tone colors that really made the music come alive, and ended up displacing the Belden 8402 interconnects I had been using in that position.

Next I’ll try the shielded DCA20GA interconnects I built on the Intact Audio SUT’s and compare them to the shielded DCA16GA interconnects that Chris built. I’ll report back when I get that done.

Here’s the moral of this story:

The Duelund DCA16GA & DCA20GA tinned-copper cables, and the Duelund 1.0 silver/silk cables provide a useful range of voicing attributes for various interconnect applications, and have allowed me to dial in the musicality & sound the way I like it, by choosing the most musically satisfying one for a particular application.

The beauty of this sort of approach is that you can build up a set of each of these interconnects, have an interconnect stable to experiment with, and still be in them for less cost than it would be for one set of hoity-toity interconnects from one of the more typical wire mavens.

Besides being a great way to fine tune a system’s voicing, it’s a heck of a lot of fun for not much money!


As always, thanks for stopping by, and may the tone be with you!

  1. I just bought a pair of custom Duelund DCA20GA headphone cables for my Audeze LCD-X headphones. The same guy, a supporter of this site named Chris Webber has made me a number of Duelund and vintage WE interconnects that I love.

    Can’t wait until I can plug them in to my system.

    • Fantastic, Ian!

      Keep me posted on some of your impressions when you have a chance to give them a try!

      Kind regards,


  2. Dear Jeff

    In your Leben – Harbeth system you choosed the Belden IC. I have the same system and I ,too, prefer the Belden IC in this position , richer, smoother ,warmer .
    Can you comment ?
    Thank you for your blog which allowed me to assemble a very musical system

    • Hi Serge,

      In my Leben-Harbeth system I’ve had very good results with the Belden IC’s, and that’s what I’m using now. I also really like the Duelund DCA16GA in that system as speaker cables, and there’s a really nice synergy with the Belden.

      Thanks for the kind words, appreciated!

      All the best,


  4. Jeff,
    I just finished writing about the 16GA interconnects and now you come along with all these different choices.

    • Howdy Jack,

      Things are moving pretty fast here on the wire front with the different Duelund cables, and I haven’t even tried the DCA12GA yet!

      It sure is nice having different voicing capabilities with the different cables, as it really allows me to dial in the presentation I like best.



  5. Jeff,

    Are you aware Duelund makes silver gold flat alloy wire in oil soaked silk?


  6. Jeff,

    I’m recently experimenting with carbon fibr for IC and use 47 Labs Stratos (also thanks to your review) as ground.
    Yesterday i made an IC with cryo-ed DCA16GA (cryo-ed by the seller) as ground.

    The DCA16GA is not burned in yet, but I find DCA16GA as ground lacking micro dynamics and some details were smoothened out… e.g. brass instruments aren’t as “brassy” and sharp sounding. But it did have some unique presence on speakers. On Stax, it wasn’t as detailed, and a little shouty.

    • Hi Kang,

      You might find the recent article I wrote about the DCA for Positive Feedback to be helpful. You can read it here.



  7. Hi Jeff,

    After long usage with different equipment of DCA16GA, DCA20GA interconnects.
    What is you opinion?
    Which RCA interconnect is better balanced DCA16GA or DCA20GA.
    In my opinion DCA16GA sound fuller and richer with better tone.
    DCA20GA sounds drier but more vivid.


    • Hi Alex,

      I don’t used balanced interconnects in any of my hifi systems, so I’m afraid I can’t help on that aspect of your question.

      Also, I don’t think there is a “best” between the DCA16GA and DCA20G, they’re just different. Which one you like the best will depend completely on what works best for your associated equipment and personal tastes. I go into this aspect in detail in the Positive Feedback article I wrote about the Duelund DCA series of cables, so it might be of some help to consult that. You can read it HERE.

      In my various systems here I use both DCA16GA and DCA20GA interconnects depending on the associated equipment and what it needs to more closely align it to my personal tastes.

      I hope that helps.

      Kind regards,


  8. Jeff, forgive me for asking a potentially silly questions, but I notice that the two-wire interconnects (non-shielded) are labeled directionally with green tape. How is this possible? In an unshielded interconnect the pin and body should be connected at each end. In a shielded interconnect one, or both, ends may have the shield connected to the body. Please help me understand how an unshielded interconnect can be directional.

    Many thanks in advance,


    • Hi David,

      The green tape indicating directionality is to help me identify which end is the source end when taking interconnects in and out for comparisons.

      It turns out that when interconnects have been exposed to a signal for quite a while, I think they sound the best when I maintain the same directionality.

      Kind regards,


      • Hi David and Jeff,

        I did an experiment with brand new DCA16GA and DCA20GA interconnects and DCA16GA speaker cable.
        They definitely have direction, they sound different in different direction with zero break-in!
        I chose direction with more focused and clear sound as a “right” direction.
