Network Acoustics Eno2

On the other hand, I have owned the original ENO & MUON. Both of which made a noticeable & positive improvement to my streaming. I now own the MUON Pro Streaming system and even with optical isolation, I find the MUON Pro & Pro Ethernet cable to be a very worthwhile addition. More natural, relaxed without sacrificing detail. Music has more body. Any thinness that some find with optical is no longer. I have placed it just before the Gold Note Integrated. MUON Pro Ethernet cable from SR switch to the filter, the attached pigtail plugs into the integrated. I have found Network Acoustic to be honest, responsive & dedicated to bringing excellent products to market that absolutely deliver on their promise. They also offer a generous money back trial period. Of course, everything is system dependent.

I owned Eno Streaming System and sold it. I didn’t like the mellowed out presentation and rolled off sound.
I now use iFi LAN iSilencer - it doesn’t do 💩 but it also doesn’t harm the sound. 
I have it before the Ethernet cable that feeds the streamer. 
 

I would recommend not to waste money, time and effort on Ethernet tweaks. Continue upgrading your components to higher quality ones and treat your room. That’s where you’ll get your ROI. 

It seems the game plan of small box companies is to keep coming out with new small boxes.  I owned eno and muon and can't really say either made a difference, and certainly not meaningful.  I do use optical isolation both by using converters out of my router and because my digital equipment offers optical connections, however, I can't say that makes a difference either, but it does sound pretty good.
