Each muon USB Cable is handmade to order in the UK and is rigorously tested against the original reference cable. The muon USB Cable is available in 1.50 metre length as standard (further 0.50 metre increments ~ to 5m.)
This is the cable we recommend using if you want to hear your DAC working exactly as the designer intended.
Using an enhanced version of our proprietary 3-core segregated cable architecture and using our latest filtering technology integrated in-line, the muon USB Cable represents the very best sounding digital interconnect we’ve made. Every element of its design and every individual component and the materials used in its construction, have been painstakingly tested for the ultimate sound quality, before being incorporated into the design.
With muon USB connected you will hear every last gram of detail in each recording, staged in a three dimensional soundscape with every instrument, perfectly positioned and separated.
This is the very best digital interconnect we can make and have heard. The muon USB Cable is recommend if you want to hear your DAC working exactly as the designer intended.
Available in USB Type-A to USB Type-B configuration, in 1.50 – 5 metre lengths as standard. Custom lengths are also available – please contact us to discuss your specific requirements.
muon is Network Acoustics’ new reference range of digital cables and filters, designed for customers who want to hear their streaming system exactly as its designers intended.
muon represents the culmination of everything we’ve learnt on our mission to realise the full sonic potential of streaming as the ultimate source for music reproduction.
With muon we took a zero compromise approach to everything, from the product design, to the choice of materials, components, and processes we use to manufacture. Each product in the muon range features our latest proprietary noise filtering technology, combined with cutting edge design.
Handmade in the UK and individually tested against the original reference product.

Why is it so hard to get really good sound quality from streamed music? To pass music data in digital form from one device to another, audio manufacturers have adopted two computer hardware standards that were originally designed purely for data communication between computer hardware devices, namely Ethernet and USB. They adopted these standards mainly due to the cheap availability of common hardware products and the ease of implementation.
The problem with this is that both Ethernet and USB are ‘noisy’, as eliminating noise was never a requirement of the original design. As long as a computer or peripheral device could interpret the data being sent accurately, any noise associated with it wasn’t a problem. With computers, its the accuracy of the content of the data that was important, not the cleanliness or precise timing of its arrival.
The noise though is harmful to the sensitive input circuitry of hi-end audio devices and can bleed through the Ethernet input circuitry of a streamer and effect critical components further down the line, impacting on sound quality.
If we can get rid of that noise and arrange for very precise data timing then we can surpass the sound quality of really good CD and really good vinyl.
What is ‘noise’ in an Ethernet network?
Noise is any signal present in an Ethernet network that is mixed in with the Ethernet data signal, that shouldn’t be there. Sources of noise are numerous and omni-present, of all different frequencies. All active devices connected to a network such as routers, fibre converters and switches emit noise; other sources such as radio signals of all frequencies from TV, Radio, Satellite, Mobile Phones and WiFi are induced into Ethernet cables as noise.
What is the effect of ‘noise’ on sound quality?
Noise in an Ethernet cable is passed into your streaming device through its RJ45 connector. This has an effect on sound quality that makes the music sound digital rather than analogue. It makes the sound-stage closed in, very much in between the speakers, lacking air and space around instruments, a bit muffled, lacking bass and pure high frequency extension, masking micro dynamics and low level details. Recordings in lively acoustic venues sound flat.
How does the eno and muon Filters work?
eno and muon filters absorb electrical noise, which would otherwise be delivered via the Ethernet cable into your sensitive audio equipment. The filters do not modify the actual data in the data stream in any way. As they are a purely passive device that would be impossible, the filter just removes the noise mixed in with the data stream.
Does Galvanic Isolation stop noise?
Galvanic Isolation is physically implemented as part of the Ethernet standard and can be found in Network Switches.
A high frequency transformer is connected to each pin of the RJ45 input connector. The reason it’s a high frequency transformer is to pass through the data signal (which is a high frequency sine wave) but block DC and low frequency noise. They don’t block damaging high frequency noise higher than the Ethernet signal as they are ‘high pass’ transformers, therefore all RFI noise mixed in with the Ethernet signal will pass through.
It’s very important to note that Galvanic Isolation transformers are only found in Network Switches, not on the input RJ45 sockets in streamers, therefore the streamer’s RJ45 input is highly exposed to RFI noise. That’s why adding an eno or muon Filter brings such a nice improvement in sound quality.
How do I install an eno or muon Ethernet Filter?
- Switch off the power on the streaming device to be used with the filter.
- Disconnect the ethernet cable from your streaming device’s network socket, and connect it to the “IN” socket on the side of filter.
- Connect the flying lead from the “OUT” side of the filter into your streaming device’s network socket.
- Switch on your streaming device.
How do Network Acoustics develop and test products?
Our main tool of measurement used while developing our products is continuous subjective listening tests. Over time we have learned exactly which parameters are technically critical.
Where do Network Acoustics make products?
All of our cables and filters are designed, developed, and hand-made in the UK.
What is UP-OCC?
UP-OCC stands for Ultra-Pure Ohno Continuous Casting.
The UP-OCC process for refining copper was developed and patented by Professor Ohno at the Chiba Institute of Technology in Japan. The license to use this manufacturing process is incredibly popular for the production of wire and cable products for the audio/video industry.
Ohno Continuous Cast is the name given to the casting process developed to help defeat annealing issues and virtually eliminate all grain boundaries in copper or silver with a unique patented process. The OCC casting method uses specialized heated moulds in order to draw a single crystal up to 125 metres in length.
With only a single crystal in very long lengths, there is an unimpeded free path for the best possible signal transfer. Along with this superior single long crystal structure, OCC provides copper and silver with the least possible oxides and other impurities.
In contrast to OCC, there are other lower-grade coppers such as OFC (Oxygen Free Copper) with a multitude of grain boundaries and other impurities. OFC has around 400 crystals per foot and despite its name has an oxygen content of about 10 ppm.
OCC delivers the purest base platform possible, allowing you to get that much closer to true absolute transparency. We think you will agree with our choice of conductor when you hear any of our products.
What are the benefits of UP-OCC?
- A true unidirectional single copper crystal, as free from impurities as possible to prevent corrosion.
- Flexibility and fatigue resistance, without impairing conductive characteristics.
- Low electrical resistance.
- Rapid signal transmission.
- Non-crystal boundaries.
- The best sound quality!
