The Silver Dragon USB transfers digital audio from a computer or portable device such as a Phone, Tablet or DAP (digital audio Player) to a USB capable DAC. We build cables for home, office or portable solutions. This product page is focused more on longer length applications while Silver Dragon Form Fit USB cable Here focuses more on portable short solutions.

Moon Audio has optimized our USB cables for audio transmission of large High Res files. Please see the notes below in our Description Tab to help you establish which USB connection is right for your application.

Quality You Can Trust

Most stock cables are made of poor, ultra-thin conductors with poor geometries, rubber jackets, and other issues that can limit the performance of your equipment.

Dragon Cables are handcrafted from quality materials in Moon Audio’s headquarters in Cary, North Carolina. All of our cables are created with ultra pure, single-crystal silver and copper strands and engineered to provide the cleanest, most musical presentation. Our wire is void of impurities and crystalline boundaries, leaving nothing between you and your music.

Silver Dragon Sound Signature

The Silver Dragon is the original cable. Silver strands clarify instrument separation, increase soundstage, and find previously lost high and mid-frequency sounds. Transients appear more cohesive and the bass tighter for a more controlled sound. The detail and clarity of the Silver Dragon make it a perfect match for classical music and other genres with many nuanced instruments.

For more information on finding your signature sound, visit our Sound Signature Guide.

Cable Design

The Silver Dragon was created with ultrapure silver conductors for the best in signal transfer for your digital music. The cable uses 99.99998% UP-OCC Stranded Silver 24AWG Teflon insulated stranded conductors with a double layer shield to ward off outside interference. The Silver Dragon USB is the most resolute USB cable on the market today for an amazing price point. So stop paying for over inflated cables and give it a try. Be prepared to be amazed at the difference it will make when transferring your computer audio catalog to your USB applications.

We offer normal USB signal transfer cables from your computer to your Digital Audio Converter as well as a host of ultrashort cables to connect your portable devices. For longer and more custom options please see the drop-down menus on this webpage to choose the selection you need.

There are two different configurations offered on this webpage. Normal USB signal transfer as well as OTG (on-The-Go) USB signal transfer. What is OTG? USB OTG is a specification that allows USB devices, such as tablets or smartphones, to act as a host, allowing other USB devices, such as USB flash drives, digital cameras, mice or keyboards, or an external Dac to be attached to them. The USB connection is terminated slightly different than in a normal USB termination. This termination essentially tells the Android-based device to output a data stream. In the case we all care about, it is releasing digital audio so your external Digital to Analog Converter takes over control of processing the digital music on your Android based phone or tablet.

In some cases a DAP (Digital Audio Player). Most DAPs like the Astell & Kern’s are Android based. So if you desire to use an external DAC with them an OTG cable is required. The OTG cable tells the AK to output digital audio. Of course, you will also need to visit the AK’s settings page to also tell it to engage the USB output. With most Phones and Tablets this is not required. Older Android-based phones and tablets in the early 2000’s used a USB Mini B connection as the standard. Slowly phone and tablet manufacturers moved to USB Micro B as the connection of choice. The same can be said for a lot of portable Headphone Amplifiers with built-in Digital to Analog Converters. These started with USB B Mini and then transitioned to USB B Micro. And today we are now seeing USB C now becoming the norm for Phones and Tablets. USB C offers a faster way to charge these devices thanks to the higher conductor count.

Moon Audio is focusing on USB C cables for Digital Audio Transfer only. Our cables have not been designed to be a Phone charging cable. The cost of manufacturing a high conductor count silver cable with conductors being used for non-audio important roles makes no sense from a cost perspective. While our cables will charge a device, our cable is based on USB specs required for Audio Transfer only. They have not been designed to be used with Hard Drives etc. When Audio circuits move past normal USB 2.0 practice I’m sure at this point we will move to more of a USB 3.x design. For USB C charging cables we have a great affordable option Here.

USB C can be utilized for both OTG and non-OTG applications as well. So when connecting, for example, one of Apple’s new MacBook Pro’s with USB C to your home Dac, in this case, a USB C to USB B normal USB connection is required. But when using your Samsung Galaxy 8 or Astell & Kern SP1000 to your Chord Hugo 2 then a USB C to USB B Micro OTG cable is required. Confused? I know it can be complicated. But feel free to contact us for help.

We also have MFI certified Lightning USB cables for Apple iDevices such as your iPhone, iPad or iTouch. Apple lightning cables act very much like an OTG cable. They tell the Apple iDevice to output digital audio. But the Digital to Analog converter must be MFI certified to accept this direct cable connection. If your Dac is not MFI Apple certified then a 2 cable solution is required. An Apple CCK Adapter followed by a USB cable. The Apple CCK, in this case, is the OTG cable. So for connecting your iPhone or iPad to your Chord Mojo or Chord Hugo2 DAC you need an Apple CCK plus a USB A to USB B Micro cable. See Here for an example of this connection kit.

User comments on the new Curious Evolved usb cable

A revelation – Curious Evolved.

I have tracked from AudioQuest to Oyaide to Curious USB and now to a new release – Curious Evolved.  The Evolved absolutely raises the bar to new heights for my system – Meitner DA2 Reference, Karan KA M2000 monoblocks to Wilson XLF speakers through Odin and Analysis Plus cables.  

Much broader and more detailed soundstage with incredible inner resolution.  Added front-to-rear depth giving a lifelike reproduction for large scale orchestral, small chamber groups and instrumentalists.  Piano files at last have extended decay along with deeply felt power in the lower register.  High sopranos retain body and richness.

I was much impressed by the original Curious, but the Evolved adds a new level of transparency, weight and emotional involvement in my system.  Most realistic musical timbre I have heard.  Great job Curious!! 

Ron D. (Australia)

Curious Evolved – enhances dimension.

I have been a long term Curious Cable user, satisfied that it is the best USB cable available.  My Magnepan 20.7’s are renowned for their ability to present a dynamic and lifelike soundstage and will quickly expose any component or cable that compresses or congests the dynamics and dimension in a recording.  I was therefore very excited to get the opportunity to try the new Curious “Evolved” USB cable.

Building on the strengths of the original cable the “Evolved” version enhances the dimension and naturalness of the soundstage giving vocals and instruments an extremely lifelike presentation with the finest details resolved and unmasked in all their glory.  Even during complex multi-instrumental passages the perception of detail and dimension remained firmly in place allowing better imaging and insight into individual musicians and therefore the group as a whole.  

A worthwhile step up from the original, the Curious Evolved USB cable is my new reference cable.

Wilhelm H. (Australia)

Curious Evolved – more detail. 

The original Curious usb cable beat all comers in my system and still is a great cable. However, when I inserted the Curious Evolved, it revealed more body in instruments, improved nuance and detail plus improved the soundstage and imagining. 

It was like I had turned the volume up and it became calm.  I am really hearing what the Nagra HD DAC can do!

Phil W. (Australia)

I have been using the the original yellow usb cable and was very happy with the sound quality to the point where I never considered any replacement.  But since I have installed the new blue cable and Regen Link my system has Evolved!  Much more detail and clarity. So smooth So impressed. Well done on another great cable….highly recommended and thanks again.

Rob Woodland discusses “dimension” in usb cables

Curious Evolved usb cable – the best we can do!

Do USB cables affect the sound? Manufacturers’ opinion [translation] • Stereo.

ru

There is an opinion that USB cables cannot and should not affect the sound of the audio system due to the fact that they simply transmit zeros and ones from point A to point B. Digital signal. But some do not agree with this and hear the difference in the sound of different USB cables. So Dave Clark decided to get some cable manufacturers’ opinions on this issue: what’s going on in the cable and whether the sound can change. And here are the results.

Manufacturers were asked the following questions:

– Do USB cables really just carry ones and zeros? And if not, then what?

– How is sending music over a wire different from sending an image to a printer? It’s just data.

– What happens in the USB cable that can affect the transfer of sound or data?

– Separate power and separate data? Interference?

Audio is streaming

David Salz, Wireworld

Digital signals are actually rectangular pulses that are recognized when a certain voltage level is reached. Any deviations from the rectangular shape in the signal will easily lead to errors.

When saving an image or sending it to print, the error correction system requests a file transfer until it has a complete copy of the original.

Audio [Asynchronous USB] is streaming, there will be a delay from constant replay requests. Therefore, instead of re-requesting the packet, the signal error correction system works, but it can correct it incorrectly.

Standard cable loss will slightly round and shift the waveform, leading to errors and data loss, color changes and distortion. The damage is easy to recognize when comparing standard USB cables and special reference adapters in which the connectors are soldered directly to each other. Creating a cable that minimizes these losses and deviations from the original waveform is the only way to reduce errors.

Cable Wireworld Ultraviolet 7 USB 2.0

Computer power supplies are excessively noisy and can affect sound clarity. In most USB cables, the power wire is in no way isolated from those that transmit data, interference from it can distort the signal and enter the DAC through the 5-volt input. Therefore, the five-volt conductor must be isolated and put through a filter that reduces distortion, or even replaced with a silent power supply.

Static in the cable can also generate interference. These triboelectric distortions also introduce changes to the signal, resulting in jitter. Reducing such interference will allow you to get a clear sound close to the reference connections.

The audiophile value of a cable does not correlate with its maximum speed

Aqvox

In past years, I had an interesting conversation with an engineer from a very large cable manufacturer, the German LEONI Group (more than 70,000 employees, turnover of 4 billion Euros). We discussed with him the production of USB cables.

From the very beginning, although not an audiophile, he agreed that the wires affect the sound quality. He knows how the design elements affect the transmitted signal. They test cables with logic analyzers for completeness and visually, for example, with Tektronics DPO7000C $30,000 USB oscilloscopes, or Lecroy QPHY USB for metering and frame transfer. This is required for USB certification.

Aqvox USB

cable Such equipment is suitable for testing, for example, at the maximum speeds for the 2.0 standard, but they do not have settings suitable for analyzing parameters at significantly lower speeds, which are used to transmit an audio signal. This explains why the audiophile value of a cable does not correlate with its maximum speed.

Real time music playback

Marcin Ostapowicz, JPLAY

Ones and zeros are logical interpretations of an electrical signal. It is transmitted via USB in a differentiated way. For the 2.0 standard, “zero” corresponds to -10–10 mV, “one” – 360–440 mV. That is, in fact, we are dealing with a very sensitive electrical (analogue) signal. High bandwidth leads to jitter and signal attenuation becomes an important problem (high frequencies decay faster than low frequencies at equal distances, therefore high frequencies are more prone to jitter). Signal degradation can be traced along the path along which it follows from the transmitter (PC) to the receiver (USB input in the DAC).

Clock reflections and inaccuracies produce jitter that affects the meter pattern and makes the signal less recognizable.

JCAT USB Cable

Music playback is in real time, so timings are very important in this situation and, accordingly, it is important to get rid of the influence of jitter. We use the following technologies for this: we reduce the inductive and capacitive resistance so that the signal impedance decreases smoothly; we take into account the surface effect and use very thin conductors; We use triple shielding to protect against electromagnetic interference.

The frequency of the processor in a modern computer reaches several gigahertz. It emits electromagnetic radiation that may interfere with the USB signal.

The integrity of the received file is not checked

Jim Aud, Purist Audio Design

It is quite logical to consider the signal transmitted via USB as a sequence of zeros and ones. However, everything is not so simple. Below a certain voltage, the signal says “this is zero”, and above a certain level it says “this is one”. That is, one can be a signal of 3.2 volts, zero – 2.9volt. Since the data transfer is fast and frequent, it is not so difficult to mix up zeros and ones. A digital signal is not just a sequence of cubes marked with zeros and ones, they are in a certain range of acceptable values, but they are not absolutely identical.

In such an environment, external influence becomes an important factor. Things like electromagnetic radiation matter. Imagine that a mobile phone rang next to a computer. The crunch and squeal that you hear is exactly the same way interference in the wire behaves. Shielding, the use of quality materials, even a filter can all help in reducing interference from extraneous signals.

The length is also affected. The longer the cable, the higher the chance of signal degradation due to resistance. Therefore, companies are moving to use higher quality conductors. For example, the USB 2.0 specification limits cable length to five meters, while the USB 3.0 specification limits it to three. If there are quality conductors in the design, these three- or five-meter wires can be used to the fullest.

What about error checking? The USB digital audio signal itself. Printing a document or picture is checked for errors. When sending a document or picture, a code is also sent with information for the receiver containing the packet size. The receiver compares this information with the incoming file.

Purist Audio Design Ultimate USB Cable

Audio transmission does not use this technology. The integrity of the incoming file is not checked because USB is an open cable. Data is simply poured into it, like into a water hose, without any bit checks, reconciliation of amounts and other decisions that are present, for example, in HDMI or when sending the same picture to print. Did you receive what you sent? Unknown.

The higher the frequency range, the higher the error probability. USB cables transmit at megahertz; At low and high frequencies, completely different phenomena affect the signal. The surface effect and reflections begin to affect the transmitted information, as well as electromagnetic radiation.

You can buy a quality cable. Pay attention to one that uses low resistance conductors and good filters. A separate power rail, which many manufacturers are now experimenting with, is also a good idea. Check the cable specification (2.0 or 3.0?) and see if it fits within the recommended length. Quality cables guarantee a clean, crisp signal with no loss or change. They can significantly reduce or completely eliminate the influence of external sources, which will lead to errors. USB cables are an important part of audio systems built around interaction with a computer.

Audiophiles should pay attention to the digital cable park

Mark Coles, Sablon Audio

From a data point of view, this is true, but the same can be said about SPDIF cables, and their effect on sound has been proven many years ago. Audiophiles should pay as much attention to their digital cabling (USB and Ethernet) as they do to analog and power cables.

If you are a developer, you need to get into resistance 90 ohm (rather than the wide range of +/- 10% that the specification allows) and pay attention to noise control are the main parameters. High-quality conductors will significantly improve the sound.

Cable Sablon Audio Panatela

It seems to me that interference and jitter are related phenomena and equally unpleasant. It is worth considering USB receivers / transmitters, which can be created not in accordance with the standard, but with a certain price category.

There are no more obscene discussions than discussing the effects of a USB cable on setup

Alex Sventitsky, WyWires

Digital interfaces in general and USB in particular are misunderstood by audiophiles due to the unclear nature of the impact on the sound of a home audio system.

Many people think that digital cables only carry ones and zeros and therefore there can be no audible difference between different cables. Audiophiles who have tested several cables often find that yes, USB cables can affect the sound of a system. In my experience, there is no more obscene discussion than discussing the effects of a USB cable on a setup.

What are zeros and ones anyway? This is binary data, which is often called machine language, in which one is “on” and zero is “off”, if we draw an analogy with a light switch, for example. Sequences of zeros and ones are used to translate human-accessible information into a language that a machine can interpret using two-state switches in its circuitry.

The USB transmitter (computer or music server) transmits sequences of zeros and ones in a predefined format to the DAC, which converts these sequences into an analog signal, and it is already perceived by the human ear.

The USB standard has 650 pages of text. I will try to highlight the key points that will tell about the influence of the cable.

No purely digital signal exists. Digital data is represented as electrical signals suitable for certain conditions. In our case, these conditions are described in the standard. Data transfer is carried out through two conductors, D + and D-, USB understands zeros and ones as the difference between the electrical signals that are transmitted over these conductors. A signal is considered to be one, at which the voltage on D+ is 200 mV higher than on D-, zero – the signal on D+ is 200 mV less than on D-.

The sequence of potential differences, or zeros and ones, is called a packet and is asynchronous, that is, after sending a packet, the transmitter waits for confirmation that the packet has arrived, and only then sends the next one.

The

USB transmitter in the computer sends certain voltages to the D+ and D- conductors in the range of 1.5 to 480 Mbps through the cable to the DAC, and this is how the process looks in a very simplified version. Sorry, engineers, I didn’t write this for you, so let’s do without sarcastic comments.

WyWires USB Cable Silver

USB cables carry an electrical signal just like analog cables, but at a much higher frequency (approximately 480 MHz). As with all electronic conductors, signal integrity depends on basic circuit parameters such as inductance (L), capacitance (C), resistance (R), and crosstalk (Crosstalk).

It is the designer’s job to reduce the potential harm that can be caused to the L, C, R electrical signal and hum. Inductance is a phenomenon in which a signal, passing through a conductor, forms a vortex flow that tries to reverse the direction of current flow. Capacitance indicates that when a signal passes through a conductor, some of the energy leaves it and is stored in a material located next to the conductor, and then flows back into the conductor. Resistance (or impedance) shows how the voltage will drop in a certain section of the length of the conductor due to its insufficient cross section in certain circumstances. Pickups – the transfer of energy from one conductor to another, located nearby. All these phenomena lead to jitter – a defect that manifests itself at a specific point in time, necessary to ensure the integrity of the information transmitted to the DAC. And it seems to me that the most guilty of it are capacitance and interference.

The 650 pages of the USB standard explain how to deal with resistance and interference, but ignore capacitance and inductance. Unfortunately, the standard development council focuses solely on USB technology as a file transfer technology, and does not address real-time audio and video streaming options.

Another aspect of USB cables is the transfer of power from the transmitter to unpowered receivers. The five-volt power rail can also have a negative impact on the integrity of the D+ and D- signals if there is no good isolation.

In the end, we should also talk about such phenomena as radio interference and electromagnetic interference. These are external effects that may affect the USB signal. Specification 1.1 and above states that the RFI/EMI shield must be connected to the connectors at either end of the cable. The USB 2.0 software will check for a continuous connection between points A and B as the devices recognize each other.

All time difference, not in data

George Cardas, Cardas Audio

In cheap cables, the signal is more rounded – and this is one of the reasons for the difference in the sound of USB cables. The lack of insulation between power wires and data wires is terrible. It leads to the appearance of several types of interference.

In the digital part, these are zeros, ones and timings – everything is not so simple here, but in general, cables are not just information transmitters, because the dielectric constant in them is not so constant and is greater than one. This leads to non-linearity in signal propagation speed, because the dielectric constant number is proportional to the number of units in the sequence, so if you cannot achieve the same propagation speed in the conductor as in the dielectric, then the time interval in which the other end of the cable receives the forwarded data , will be inconsistent – and this leads to jitter, which affects timings and so on. We are very prone to timing errors.

Cardas Audio Clear Serial Buss

Cable Sending a file is actually no different from sending a photo – the difference is that the photo is not transmitted in real time, unlike the sound. The whole difference is in the time, not in the data.

Materials must be clean and reliable – dielectrics are important, more precisely, their dielectric constant is important, which must correspond to that of the conductor. I prefer PFA, it has a good dissipation factor. Metals should be soft and clean, there is not a huge difference between the parameters of silver and copper, except in twisting geometry, but I prefer silver.

Digital cables are analog cables

Joe Cohen, Lotus Design Group

The answer is simple: digital cables are analog cables. They are subject to the same problems as phono cables and interconnects. Materials and manufacturing techniques affect the behavior of the cable, both with self-generated noise and with external noise.

Cable Lotus Design Group Photon USB

An ideal digital wire will not be affected by these distortions at all. High frequencies generated in the digital environment pass through all currently popular protection options and require remarkable measures to suppress them.

The digital signal must reach the DAC square

Joe Reynolds, Nordost

There are many factors to consider when designing high quality USB cables. In order to achieve ideal performance, it is necessary to reduce noise, hum and jitter in the cable. To do this, you should consider, again, some things. Timing errors that can be measured produce artifacts that are noticeable when listening. A digital signal that is a square wave must get from the source to the DAC as square as possible. If the cable bandwidth is not wide enough, or if there is some interference, the signal at the corners will be smoothed out and its edges will not be as square and clean as needed. This will create problems in the decoding circuitry of the DAC, which, again, will lead to noticeable artifacts when listening.

Nordost Blue Heaven USB

Cable The most important factor in cable development is the high geometrical accuracy of the conductor structure. This results in signal loss over long distances. This is influenced by the material from which the conductor braid is made. Cheap cables use high capacitance plastic, which quickly “eats” the signal over a short distance.

Good shielding that protects the cable from external interference is very important. It is also necessary to separate power lines from those transmitting a signal. In our company, we use double shielding with silver-plated braided insulation and an additional layer of foil.

We audiophiles are trained to hear the difference in the sound of different wires

Rob Woodland, Curious Cables

I came to designing USB cables with a slightly different vision than most designers. I’m not an engineer, but an audiophile with experience designing and manufacturing high end connectors.

I’ve spent a lot of time researching USB cables and have found the best products from different manufacturers. And I came to the conclusion that the USB specification can be used to create cables with a high transfer rate, but this does not affect the quality of the transmitted sound.

Charlie Hansen of Ayre Acoustics provided the best explanation. He described the digital signal as a voltage ripple representing zeros and ones – that is, it is an analog signal.

Therefore, the first step is to learn to look at the USB cable as an analog one. In this case, it is most similar to a balanced interconnect cable – both support differential data transfer mode.

What is the difference between sending music and sending pictures? And there may be no difference! It’s just that we audiophiles are trained to hear the difference in the sound of different wires.

The sound in the USB cable can be affected by everything. Computer audio is another battlefield, from an unfriendly computer/server to radio and electromagnetic interference in the data transfer process. Interference, more interference!

Curious USB Cable

Inside the cable, interference is generated by a five-volt power wire and a ground wire. How to deal with this is the difference between many design approaches. Braid materials can accumulate charge in themselves and release it, and affect the speed of signal propagation. Don’t forget about the connector itself.

Separate power and data is a logical response to interference from a five-volt core. Away from the data conductors, it is good to shield. Curious uses shielded mini-coax wire. Works great. Every design element needs to be taken into account if you really want to achieve perfect sound quality.

As a designer, start from the very beginning – select the material for the signal conductors. And all conductors sound different. Copper or silver? Twisted, Litz or solid? What section? Be sure to listen. Braid and dielectric also need to be selected. And then think about power and grounding. And implementation.

Something like output

What do we end up with: interference, timing, resistance, errors. Mistakes. Interestingly, many agreed.

I can hear the difference in the sound of the cables. The difference is noticeable in specific places, and not in general. She is barely noticeable. But very important.

Of course, you may not hear the difference in sound, or, on the contrary, find the difference, just to bet. After all, a USB cable is not so simple at first glance, but for someone, and for the first listening. What do you think?
