Network Acoustics Muon ethernet filtering system - Improving streaming sound quality

Network Acoustics recently rolled out a new top tier ethernet filtering system named Muon. It betters their already highly effective ENO offering which I purchased some 18 months ago.  I posted about the ENO filtering system back then and you can read it at the link located at the bottom of this member review.  

Everything I said about the ENO filtering system also applies to the new Muon system.  However, the Muon system offers even better sound quality by removing a greater amount of electronic and RFI/EMI noise.  The Muon filter is a passive device so their is no need for a power supply or power cord. That’s great! 

Like many of my fellow Agoners, I have come to depend on Qobuz and Tidal streaming for my music playback. I have not used any physical media in over 5 years, but also realize today’s servers/streamers can all benefit from digital noise blocking systems such as the Muon.  From high end audio switches to high quality ethernet cables I have learned they can all improve the sound quality of our streaming front ends.  I have tried going the fiber optic route and used other products such as the EtherRegen and while they do improve sound quality I find  the MUON system more musically engaging and compelling.  Here is my current digital front end:

(Netgear NighHawk modem/router powered by an LPS > Network Acoustics ENO ethernet cable> English Electric 8Switch powered by an LPS > Network Acoustics MUON ethernet cable > MUON ethernet filter > Innuos Zenith III >  Tchernov Ultimate USB cable -Mojo Audio Evo dac)

The MUON system is made up of the MUON filter and Muon ethernet cable.  You can buy these separately, but you’ll receive a nice discount by buying both as a system package. Here is a link to the Network Acoustics Website:

I purchased the MUON system and have been enjoying it for several months now.  I feel it betters the ENO range in several important sonic ways. The noise floor is further reduced revealing more inner detail of instrument and voice.  This increased inner detail reveals subtleties previously lost.  In the end my music sounds more real and less reproduced. For me, improving realism is everything! 

With streaming it seems more difficult to obtain a nice 3D presentation as compared to a high end CD spinner.   Sometimes streaming can sound relatively flat compared to CD playback.  I found the Muon filter system delivered a more immersive experience due in large part to improving the 3D performance.   

For me the Muon filter is well worth the asking price as it made my listening sessions even more enjoyable. The rest of my system includes a Circle Labs A200 integrated amp, Fyne F704 speakers with upgraded crossovers and internal wire, and both Hijiri & Tchernov cabling.  











@mitch2 : nothing in your two links indicates the existence (or lack thereof) of gigabit Ethernet inputs in your Mojo server. You will have to ask the company. Needless to say, everything in your chain (internet speed, router, switches, cables) must also be gigabit rated. If just one is not compatible with Gigabit speeds, the entire chain will not


fiber media converter to optical cable to another converter for fiber to ethernet, short, high quality shielded ethernet cable to streamer then short usb to dac.

The optical section removes all the “noise” from the copper wires of the ethernet on the “dirty” side at a much lower price point then trying to clean up copper to copper and passes only the on/off signal.

If you don’t have the funds to spend on these expensive ethernet based filtering systems, the optical section is the way to go.  Much “cleaner” and more detailed sounding now.

And, there is no reason to spend as much on the rendu stuff. Simple trip to newegg to get a couple converters with the appropriate SFPs and cable will get you there.. You could spens a little more than I did, but, I just went to mid-high on, not the most expensive, just price/performance levels along with a little bit better of an shielded ethernet cable for connecting to streamer.

We’ve found optical converters actually generate considerable noise in their conversion from photons to electrons, plus the extra noise injected from their PSU’s

It sounds like it’s the answer, but it doesn’t sound so good - think listening to music from source (Streamer, CD Transport) to DAC via an optical Toslink connection versus a good RCA or AES electrical connection.

@lalitk Have you compared the JCAT Signature LAN Gold to the Muon Pro streaming cable yet? I'm wondering about this match-up because they are very close to the same price.
