Ethernet - Analog/Digital Signal Clean Up


Curiosity got the better of me recently and I tried a pretty cheap tweak where I used two Fiber Optic converters between the eero access point and my Lumin U1 Mini streamer. Converted from copper Ethernet to fiber optic then back to copper and then into streamer using my Supra Cat8. 

I was pleasantly surprised with the improvements this change had brought into my system and now I am wondering if I can do better. One other aspect of the current configuration that I don’t like is the clutter - each unit comes with it’s own power supply and add to that a fiber optic cable. I already have a spider web of wires and am not looking to add to that. 

Objective is to have as much noise, RFI and EMI removed before it reaches the streamer. 

Seeking opinions on the following units from those who had tried them in their systems:

  1. English Electric Network Switch 8 (Silent Angel is pretty much the same thing)
  2. Uptone EtherREGEN (currently out of stock)
  3. Network Acoustics Eno (box or streaming system)

 

What is your experience with these units?

Anything else to add to the above list? 

 

Thanks in advance!

@sns  thanks for the link.

He’s not exactly raving (he if can rave) about the Muon. But, he does admit it to being better than the Eno, which he was very enthusiastic about. So I guess it’s a question of trying it out. Its impact will be dependent on the streamer mostly, I guess. I don’t have one of those rinky, dinky Grimm streamers, just a "common-or-garden" Zenith Mk3.

I’ve decided to "what the heck!", and get one as well and try side-by-side with my new Eno. If I don’t I’ll always be wondering, so now’s the time to do it while my Eno is in its 30-day return period.

@fthompson251 ,  I discussed my setup with the Network Acoustics guys before purchasing the Eno.  The advice I got was to put any switch (doesn't have to be a fancy audiophile one) between your wifi router and the Eno.  The switch should have a decent power supply.

I have a TP-LINK TL-SG105S with an iFi iPower X 5V.  As a noise removal step, it's only about £120, so quite the bargain.

If a switch is not needed in your system for switching duties then what good is having one in the chain (as discussed in recent posts in this thread)? In my network, the only hardwired device is my music server, since everything else is connected by Wi-Fi. I can run the Ethernet cable directly from the router to my server, which makes me wonder whether the supposed benefits of clocking and noise isolation provided by “audiophile” switches is of any value, or just another myth coming from the marketing department to sell us more stuff.

Hans Beekhuyzen would have you believe there are benefits in clocking and isolation provided by having a switch as he shows in his “simulated” jitter graph, while Paul at PS Audio and Amir at Audio Science Review both indicate there should be no benefit resulting from the switch, which Amir shows through his measurements saying, “jitter and noise are extremely easy to measure.” Of course, as audiophiles like to say, “everything can’t be measured” and “if you hear the difference but can’t measure it, you are probably measuring the wrong things.” All I know is that in my system the identifiable sonic results of digital add-ons like switches is usually so subtle that I cannot reliably say they improve anything.

@mitch2

As with anything else in Audio, the quality of switch and implementation matters, not to mention the upstream components (like streamer, DAC and so on). I do not know what is your exact setup but I’m using a very high quality switch in my system and it has made a profound improvement in the SQ of my digital front end.

Before buying my current switch, I have tested other Ethernet switches under $1K and they had a minimal or next to nothing impact with ENO filter. Every system is different, so I encourage everyone to do trials and keep what works best in the context of your system.

"I have tested other Ethernet switches under $1K and they had a minimal or next to nothing impact with ENO filter."

@lalitk - I respect your experience and can see that you are currently using the $4K Telegärtner M12 Switch Gold in your system.  However, your comment about "minimal or next to nothing impact" resulting from switches "under $1K" would then rule out the claimed benefits from a number of under $1K switches that are advertised to dramatically lower noise and reduce jitter, such as:

  • English Electric Network Switch 8
  • Bonn N8 Silent Angel Switch
  • UpTone Audio EtherREGEN
  • AQVOX AQ-Switch SE
  • Fidelizer EtherStream Network Switch
  • SOtM sNH-10G Ethernet Switch
  • NuPrime Omnia SW-8 Ethernet Network Switch

I noticed you qualified your observations "with ENO filter" so maybe some of the above switches have a larger impact when used without the ENO filter, particularly in systems where there is significant noise on the network cables for some reason.  I guess I keep coming back to -  if I can't hear it, if it can't be measured, and if I don't need a switch, then what benefit am I getting for the money?  Everybody's system and hearing are different but I struggle with the dichotomy between claims of technical superiority by manufacturers and reports of profound sonic improvements by listeners compared to the absence of any measurable differences (Audio Science), and comments by other industry professionals (Paul at PS Audio and networking specialists on these forums) who say these Ethernet switches cannot make a sonic difference wrt to reduced noise and jitter.  Of course the final straw is that if I cannot hear it in my system then it provides no value to me.
