FAQ – Frequently Asked Questions (Cables)

1. Are the Duelund cables used in your product lines different from other Duelund cables makers ?

We are using Duelund tinned copper wire DCAXGA600V in a 600v PolyCast sleevee. There are three types of wires: 12GA, 16GA and 20GA: 

  • 12GA: Total diameter for copper core 2.2mm, a total of 63 strands of 0.23mm parallel thin core wires
  • 16GA: Total diameter for copper core 1.3mm, a total of 26 strands of 0.23mm parallel thin core wires
  • 20GA: Total diameter for copper core 0.9mm, a total of 25 strands of 0.14mm parallel thin core wires

Other cables makers mostly use DCAXGA – Tinned copper multistrand wire in a cotton and oil dielectricum. We do not use DCAXGA with oil cotton because it is not suitable for our design and our applications.


2. Are you using the Duelund Silver cables in your product lines ?

No, Duelund do not have OCC Silver. Duelund only have the flat Silver in oil wire and Silver cotton in oil wire. We would like to use the best Silver, OCC 5N Silver in our ranges of product cables. We selected the OCC pure Silver single solid core wires with 7 types of different size: 15GA, 18GA, 24GA, 26GA, 28GA, 29GA and 32GA.


3. Are your Duelund product lines different from other cable suppliers?

Yes, other cable makers mostly use “single-wire” design, and most of them are unshielded, which is relatively a simple design (cable and plugs only).

Other cable makers:                                                           

Our Product lines:      

For us, we use multiple combinations of Duelund cables, add shielding and vibration control materials to achieve highest quality sounds.

Audiolund cables are handmade and designed with emphasis on 3 aspects:-
  • Conductors – build and optimize with multiple combinations of Duelund cables (12GA/16GA/20GA) to maximize sound quality. Added the 5N OCC Silver cables for 2 new series of cables. 
  • Shielding with multiple different types and/or layers of shielding material aiming to reduce electrical noise from affecting the signals, and to reduce electromagnetic radiation that may interfere with other devices (eg. electromagnetic interference EMI). 
  • Vibration isolation with multiple different type/layers of vibration control/damping material. The aim is to retain the original signal and to minimize signal transmission loss.

Therefore, our finished cable products are relatively thicker and heavier, which is inevitable in order to achieve highest quality sound.


4. What kind of solder do you use for your cables? 

We use Qualitats-Elektronik-Lotzinn QEL, a German high-purity high-density top grade audiophile solder wire. QEL is the European solder wire OEM factory for many audiophiles solders.

Composition: S-SN (tin) 90%, X stabilizer formula 2.4%, Ag (silver) 7.5% Au (gold) 0.1%. 0.75MM.


5. Why do you use aeco plugs?

aeco is a premium high-end audiophile brand from Taiwan. aeco is a sub-brand of AEC plugs in Taiwan (established 30 years ago). aeco is also an OEM supplier of Australia’s famous bullet plugs KLEI (Keith Louis Eichmann Innovations) and ETI plugs.

6. Can I choose or change to another branded plugs?

Yes. Note that we matched and tested the plugs used in our cable series. Those plugs are selected with special consideration for pricing, performance and quality. If you want to change to another branded plug, it can be arranged. Please contact us in advance. 

Some common questions about cable testing

* Cable is not a device, Cable will not produce sounds or make noises. Cable will transmit sound only *

1. Why no difference in the sound of the cable?

We believe that Audiophiles should have the strong capability to distinguish the difference in quality of sound. Duelund Western Electric sound and OCC Silver sound are relatively very unique sound, that could be easily identified. In theory, the sound should be different from the sound of your existing system. Therefore, audiophiles should be able to hear different in sound quality. Understand that the new cable may not match well with the sound of your existing systems, or you may not like the new sound, but it must have a different in sound. However, if you hear no difference in the sound for the new cable, then, most likely it is due to an unexpected “bottleneck” on one/some parts of your system (could be on equipment, cable, power supply, speakers, etc.) This is a “bottleneck” situation, meaning the ‘performance’ of that particular item/link has reached the sound limit/peak, so you will not able to hear the sound difference whether it is a cheap cable or an expensive cable. Only if the “bottleneck” in that link is resolved, the sound of your system can reach to a higher level. If you want to keep status quo, then our cable is not suitable for your system.

2. Why do I hear noisy/unpleasant sounds?

Please remember that “Cable is not a device, it will not produce sound.” A good cable will perfectly transmit the sound signal in the device, transparently from the front end to the speaker. When you hear a noisy/unpleasant sound, it is most likely that the audio source is not perfect, and the noise has been transmitted by a good cable. It is recommended to take some time to find out the root cause, or to examine your audio source. When your audio source is better, good cable will transmit the sound signal perfectly, and you will hear the perfect sound.

3. Why is the sound of my system unbalanced?

The sound of Duelund cable is relatively balanced and transparent, with many details. If your system is in an unbalanced situation, with Plus+ Plus+ Minus- Minus- then balance (+ + – – = 0). However, if you add a balance cable (0), take away the Plus “+”, then it will become Minus “-“. So, it is necessary to find out the root cause to have a perfect sound. In a balanced sound system, you will hear a very good sound.

4. Why there is no “feeling” for this cable?

It takes a while for the new cable to run-in for a better sound. Although it is possible to fall in love at first sight, it is easier to fall in love over time. Only by slowly testing, slowly matching, and slowly reconciling will there be a good sound. There was an audiophile who could determine the quality of the cable within a day, no comment for that. Run-in the audio cable is troublesome for audiophiles, however you can slowly experience the fun of run-in the audio cable.

[This is related to matching of whole equipment/cables, need experience and handwork to achieve this]


5. Why do different recordings have different effects? Good recording sound good, but bad recording sound very bad?

If the audio source or recording is good, a good cable will perfectly transmit the audio source signals to the speaker, then you will hear good sound. Conversely, if the audio source or recording is bad, a good cable will also transmit all the audio source signals (incl. bad signals) to the speaker, and the badly recorded signals will also appear in the sound, and you will hear bad sound. A good cable should be balanced and transparent. It should be sending all the signals existed from direct recording, without concealing signals, without adding extra signals and keeping all the signals there. This should be the characteristics of a good audiophile cable.

[This is not related to cables, good cables should perform like this]


6. Why can’t I hear the sound that I like?

Audiophiles are basically divided into two categories:
1) Go for original sound only:  Those who like the original sound of the original recording, those who like the true sound of all recordings.

2) Go for good sound only: Those who like good sound only, those who like to have all recordings, incl. bad recordings to sound good too.

1) Go for original sound only

  1. If you belong to the first category who likes the original sound, then our cables can basically meet your requirements. With a balance system, when you use our cables, I believe your system will sounds more transparent and sounds good. 
  2. However, if your system sounds bad, the sound is unpleasant with our cables, personally, I believe your system is unbalanced. When you hear noisy/unpleasant sound, it is most likely that your audio source is not perfect. If you want to improve the sound of the system, you will need to find out the root cause or upgrade your equipment. If you want to keep status quo, for this case, our cable is not suitable for your system.

2) Go for good sound only

  1. If you belong to the second category who likes good sounds, your system should sound better with our cables. A good cable should be balanced and transparent with all details, full bass, sweet midrange and silky high. On a balanced system, you should hear all the good sounds.
  2. However, if you don’t hear the sound that you like (it is a personal preference, not necessarily with right or wrong sound) , personally, I believe your sound system is unique. There is no right or wrong to choose the sound that you like. Since it is a unique sound, It is more economical to keep your original cable, otherwise, you may need to change the equipment. If you keep status quo, our cable is not suitable for your system.

[This is related to expectations of individual audiophile]


Cable is not a device, Cable will not produce sounds or make noises. Cable will transmit sound only. Bad cable will transmit less sound signals with less details or hide signals. Good quality cable will transmit all sound signals with all details, including bad sound signals or noises from the audio source.

Our cables’ design policy and sound characteristics are based criteria set by most audiophiles. It is understandable if the sound of your system is incompatible with the sound of our cables. There are too many different audiophiles setup in the market, we can’t fulfill all the expectations of All audiophiles, so we choose to meet most of it but not all of it. If you cannot hear the sound that you like and want to keep the status quo, believe that our cable is not suitable for your system.
