Network Acoustics Products?

Fellow Audio Fanatics - 

I recently updated my Innuos ZENith mk3 to their 2.6 software. While I was initially incredibly impressed with the sonic upgrade. While the upgrade has provided a more resolving sound, I am now hearing some digital glare and harshness in the system. 

And I had just been sure I had things dialed in for awhile…! 

I’ve read some older forums where Network Acoustics and their filtering devices come highly regarded. I was hoping some of you with direct experience to provide some guidance. 

  1. What impact has the eno, muon or tempus products made in your systems? 
  2. While I don’t think I’ll be able to invest in the Tempus, wondering how big of a difference I would find between eno and muon? 
  3. Do I need to purchase a network switch to sit between my WiFi extender and the Network Acoustic Products? Sorry, but I seem to read contradictory things on that front… 

Thanks in advance! 






It’s a fair and good question. I’ve found everything makes a difference, it’s just a matter of degrees. 

I invested in the NA Eno (with cable) and initially tried it alone but didn’t hear much of a difference. Then I put in an improved switch (English Electric 8) and things got a bit smoother. Was it the filter, the switch or the combination? I’m guessing the latter. I ended up keeping it though considered returning it. From others experience, the muon is a noticeable step up.

I also auditioned the Nordost QNET switch and power supply. It was better than the EE switch (as it ought to be for 5x the cost) but I decided it wasn’t enough better to justify the extra cost. And, I objected to the notion that I needed to run yet another inefficient power supply giving off a fair amount of heat - for a network switch.

At the time, I was using a mesh system w/ one of the nodes nearby so I could connect my streamer to it.  Most mesh systems come with noisy (EMF) wall warts. Without going into the details of my network idiosyncrasies (other than I can’t recommend Linksys, and can recommend Netgear Orbi), I am now connecting my streamer via WiFi and no longer have the Network Acousts Eno or English Electric switch in system. (I should probably sell them cheap but am lazy - let me know if any readers are interested). 

Not all streamers work well on WiFi. Some work very well - mine does. I’ve not compared WiFi vs Ethernet in my system but my network is now stable and I don’t have a wall wart near my sensitive gear.

While it appears I’ve danced around your question - it was more to illuminate:

1) If you now have a wall wart near your digital anything - try to get some distance.

2) what’s the rest of your cable hygiene like? Any parallel runs of power cords? If so, try to adjust them so they cross at 90 degrees. All cables (power, interconnects, digital, speaker) are antennas to some degree. They broadcast and receive. Better cables do this less. How we dress cables in system makes a difference.

3) How are you connecting your streamer? The software update might be revealing things that could be addressed by the qualify (or lack thereof) of your USB, s/pdif or AES/EBU cable. 

4) Did the software update change any settings?

5) Given the above, you might very well benefit from the networks acoustics and an upgraded switch. Those who have actually tried them generally say they help. It’s just not night and day (in my experience).

Let us know how it goes.

I don’t think "digital glare and harshness" exists. I’d look elsewhere in my system. DAC?  Speakers, which tweeters?  

My guess is you became awaware of this harshness listening carefully for hanges in your system after the upgrade and now you can't unhear it.  

You can proabably uninstall the update and my guess is it will still be there.


I’m with @carlsbad2 on this one. 
I’ll add that I owned Network Acoustics Eno Streaming System. It mellows the sound ever so slightly but it has nothing to do with digital artifacts such as harshness, glare, etc. That’s your components, speakers and or room. Don’t waste money on bandaids. Address the root cause. 

i agree with the comment expressed that the na passive filters tend to smooth/dull the sound of the streamed content subtly

i prefer the etherregen (and outboard clock) to handle the incoming ethernet feed personally, it is what i settled on after trying the eno and muon... it is more boxes and power supplies and so on, but to my ear the sound is purer

I did a lot of optimizations (tweaking for some) in my digital stack. Placing a Network Acoustics Muon Pro Ethernet filter and cable (Streaming Pro) has yielded a much more organic and less shouty (harsh) sound.

DAC’s do not like it when high frequency noise is injected via USB / Ethernet or the power grid (use a very good power cable).

I cannot recommend the Streaming Pro high enough…

But, a very low noise music server is the source, that should be noise free to begin with.
