- Excellent Audiophile Vintage Western Electric sound, reproduced by Duelund Tinned Copper cables
- Excellent Audiophile Modern Pure Silver sound, reproduced by 5N OCC Silver/Duelund Silver Foil cables
Audiolund cables sound very neutral, transparent and balance. It retains the original recorded sounds and transmits them fully.
1. Are the Duelund cables used all authentic Duelund cables?
Yes, all Duelund cables are authentic Duelund cable, directly imported from Denmark.
Here is an example for invoice and Bank transfer payment to Duelund Coherent Audio, Denmark
2. 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 sleeve. 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 DCAXGA oil cotton is only good for bare wire (without shielding) applications. Since we are using multicore cables design, so it is not suitable for our design and our applications. Note that the core wires are the same for both PolyCast sleeve and oil cotton, both using same number of copper diameter and same number of strands and parallel thin core wires. Since our cable design with multiple shielding and vibration control are much better than the simple bare wire oil cotton, the sound performance is much better.
Lately, we included new versions of cable series with Duelund Silver Foil V1 wire, as an option to replace the 5N OCC solid core wires, mainly 15GA (1.5mm).

4. Are you using Duelund Silver cables in your product lines?
Yes. New versions included Duelund Silver Foil V1 wires, as an option to replace the 5N OCC solid core wires, mainly 15GA (1.5mm). Duelund Silver Foil is a flat Silver in oil wire and silver cotton in oil wire. There are many options of 5N OCC Silver wires, 7 types of different size: 15GA, 18GA, 24GA, 26GA, 28GA, 29GA and 32GA, however, currently one type of Duelund Silver Foil V1 only.
5. 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). Audiolund designed, and built with multicore of Duelund cables, and also mixed with 5N OCC Silver/Duelund Silver Foil cables. All cables are also properly shielded, isolated with damping material. A unique multicore cables design, awesome sound and excellent values for money.
Other cable makers:
For us, we use multiple combinations of Duelund cables, add shielding and vibration control materials to achieve highest quality sounds.
Our Product series:
- 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 (e.g. 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 to achieve highest quality sound.
6. What kind of solders used for your cables?
We use two types of solders:
- 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.
- WBT-0820 0.8mm 4% Ag Silver Solder Wire Germany. The halogen-free flux is gentle on precious metal surfaces. The melting temperature is extremely low at 180 degree. 4% silver content, good fluidity, easy to weld, solder joint full bright for high-fidelity sound and a variety of precision electronic components welding.
7. Why 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. Taiwan aeco High-end plugs: https://www.aeco.tw/
On top of aeco plugs, we also included plugs from Furutech, WBT, Viborg, KLEI, Monosaudio etc.
8. Can I 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. Cables 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 sounds and OCC Silver/Duelund Silver sounds are relatively 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 be 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.
Noted that new cables are generally need to burn-in to sound better. Believe that it needs at least 20-100 burn-in hours to sound reasonably good. Burn-in audio cable is an evitable process to get good sound for all audio cables.
[This is related to an unexpected bottleneck in the system]
2. Why do I hear noise/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.
[This is related to quality of sound/audio source]
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.
[This is related to True Balance of whole sound system]
4. Why there is no “feeling” for this cable?
It takes a while for the new cable to burn-in for a better sound. Although it is still possible to fall in love at first sight, it is relatively easier to fall in love over time. Only by slowly testing, slowly matching, and slowly reconciling will there be a good sound. It is unlikely that all cables will sound at its best immediately when 1st plug in. There was an audiophile who determined the cable quality within a day (How?). It is definitely inaccurate to judge the cable quality within a day without system matching and without some burn-in process. Burn-in the audio cable is troublesome for audiophiles, however you can slowly experience the fun of burn-in the audio cable.
[This is related to matching of whole equipment/cables, need experience and handwork to achieve this]
5. Why 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 major 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
- 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.
- 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
- 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.
- 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]
7. Can your cables increase the resolution, but still maintain dynamics and a good sense of music?
Personally, cables with the highest resolution often ignores the overall balance sound of a cable. Suggest to consider the overall balance of the cables in your system, and the overall performance, rather than just pay attention to the cable resolution. Cables/Wires are not devices/equipment, so they do not create sounds or generate sounds. A good cable only transmits signals in a perfect balance, without concealing or blocking signals. I believe your system equipment or speaker should be designed to increase the resolution, maintain dynamics with a good sense of music. And, this should not be the “duty” of the good cables. A good cable is designed to transmit all the signals transparently and naturally without generating different sound. A good cable should be natural, neutral, transparent and balance. It retains the original recorded sounds and transmits them fully with its own cable sound characteristics.
[This is not related to cables; A good cable still needs good equipment to help to perfectly restore the original sound quality/effects.]
Cable is not a device; Cable will not produce sounds or make noises. Cables transmit sound only. Bad cable will transmit fewer 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 fulfil 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.
