Galvanic isolation from router to endpoint

Hey all Roonie’s

Looking to do mentioned. Think off Pink-Faun adapter or from Sonoro…Maybe thehe is something else outthere…any thoughs

My setup is

Roon ROCK > Router > Allo UBridge Signature > Gustard X16 DAC…All devices ethernet cabel


My first thought is that this is easier asked then answered.
What do you want to isolate, only ethernet, power to your setup, both…?

If you search the forum, there is a lot written on this topic, it is heavily discussed, and disputed.

Write what you want to achieve, be specific about your equipment and you probably will get some pointers.

Ethernet is galvanic isolated by design.
If you want to find out more, google is your tool.


Thnks for ur answers…
What i want is, to do it right and get the most out off my cents.
This time being i have no problems with noise or anything else…but have to follow my brain, when it is running through…what can i do with my stuff to make it better…thats all…but a lot in my world
Its a thing when i hear some music and get desturbed…maybe thats another topic for that some off u can relate to
Thnks again…

The USBBridge Sig is really well designed. And your USB DAC is really well designed too.

If you really need/want to spend money on digital isolation, isolate the DAC’s USB input with something like the below. See if you can buy and return for refund if it doesn’t change anything for you.

As said above, Ethernet cables are already isolated by design, especially at higher categories (7 and 8) - not sure what you intend to gain beyond that - unless you believe in the esoteric properties of certain audiophile cables, of course, for which countless threads already exist around here.

And you might even try Intona in between ROCK and your USB DAC (and selling your USBridge Sig…)

Thnky all for answers
dabassgobomboom…Intona…Whats that?

It’s just a Google away

Yeayea…Thnks…1. again

Ethernet already has galvanic isolation. I’m repeating that because it seems it doesn’t matter how many people say this others don’t want to believe it. If you don’t want to believe it then you have 2 options:

  1. Fiber. This can be complicated and get expensive but swapping from wires to glass/plastic between router and endpoint is an option.
  2. Buy one of the many isolating devices from many different manufacturers out there. The problem with this is… since Ethernet already has galvanic isolation its near impossible for the claims of these devices to be tested. “More galvanic isolation” isn’t a thing. It either is or it isn’t (and ethernet is).

Now, I’m not saying you won’t hear a difference by using one of these devices… and isn’t it about the enjoyment of listening? No matter what we hear coming from the system, if it provides enjoyment it’s a good purchase. So, go forth and experiment. The Uptone etherRegen is popular. The Sonore opticalRendu is popular. The pink-faun you mention is popular. There are “audiophile grade” switches. The list is pretty endless. But again, “more galvanic isolation” isn’t a thing. But your belief that it sounds better is and that’s more important to your enjoyment of your system.

Edit: I want to add that the Allo USBridge Signature is an isolating device. It’s “30+ LDOs on board” and various isolated power rails are there to “isolate” the USB port from any noise or other nasties that would otherwise be carried onto the USB cable. Additionally it’s suggested, and Allo sells, to use a nice linear power supply with the device which further benefits these characteristics of the device. Some have even found running a ground wire, which Allo provides thumb lugs for on their power supplies, between the USBridge and PSU to be of benefit. Is it the best reviewed / tested device on the market? No, not from what I’ve read/watched (but I have nothing to compare it to). Is it a step up from most other, cheaper, solutions? Yes.


ipeverywhere…Thnks for ur thoughts

Yep…Psykoacustic is a powerfull thing…in our mind…but…il try to live it here and thnks again

Thread closed.

according to Beekhuyzen, this ethernet filter is the best improvement: the network acoustics eno. Better then the Silent angel bonn and the Etherregen

This is handy! if you really want be sure to have isolation. Pretty much famous already in the hifi. It was a real upgrade for my system. Never know how it would work in others. But loads of positive sounds from it.

Cheap and doable for most people wallets.

Have fun and enjoy the music

If your DAC can be affected by the Ethernet connected to a USB endpoint like the Allo USBridge Signature, time to get a better DAC. There’s no technical reason for a DAC designed in the last several years to be affected audibly by upstream digital components.

As I was rudely schooled by Mark_Brown in this thread:

Ethernet is galvanic isolated, without exception.

If listening to music gets you “disturbed” (fatigued?) then I doubt Ethernet cables are going to help you. You need to get to basics. Try different loudspeakers, different room placement, maybe some room treatment–even just curtains or carpets. Even DAC’s and amplifiers are second order differences, cables third order–in my opinion, Ethernet cables and peripherals that actually function make no difference at all. If music doesn’t bring you joy there is something terribly wrong. No small order improvement is going to help.


According to me, Mr. Beekhuyzen is just making money by product placement.


Imho, it is almost impossible to overstate just how important understanding the “sound” of your Room and putting in correct room treatments is to setting up a listening area.
