"Audiophile Grade" Ethernet Switches - The new generation
@David A - thanks for the in-depth response. The issue you describe - hopefully just a single-occurrence - can be found reported numerous times in the Roon forums. Different hardware, networking, endpoints, etc... but similar symptoms. I suspect these occasionally occur due to the vagaries of home LANs and usually quickly resolved.

Pretty sure I'll pop for an EtherRegen soon... (just as soon as I finish paying off our heavily loaded credit cards from the holiday season ;-)

Often problems with streaming is poor network stability. Under all the years I have been streaming a solid network built with quality stuff means less problems and often the routers that the ISP provides is not any good.

Today I have fiber to my house and the ISP just provides a converter and you are free to use any router. I got an Ubiquiti Edge X SFP and seperate acesspoint for wifi. From the Ubiquiti I run fiber to my etherRegen and on the A-side my NUC with Roon Rock is connected. On the B-side my dCS Network Bridge is connected and during the two months I had my eR it has worked without any glitches.

Qobuz Studio -> Roon ROCK on NUC -> Uptone etherREGEN -> dCS Network bridge -> AES/EBU -> DAC
HD Plex 200W PSU (4 rail for ISP fiber, router, switch and NUC)

Second system
Qobuz Studio -> Devialet Silver Phantom, Devialet Tree

I wonder if it will last for long and if it does start to have problems over time (within the warranty) what will/can Uptone do about it?
Did you post your listening impressions any where?  And are you still concerned about the heat?
A pair of Devialet Phantom Golds, system described here.

@Snoopy8 no I have not written much about it, I did some A/B comparisons but during the first time I had the eR I changed cables between my dCS and TAD equipment and got new feet for my speakers so hard to say what did what.

Regarding the heat I have solved that so now it runs around 37-38C.

Hello Octaviars, mechanically well solved! 

For technical reasons, overheating of the electronic components (electrolytic capacitors, chips etc.) less durability, I will stay away from it.  Development, technical and electronic, bull....Angry
Just my opinion.

The manufacturer should look up what the DIN standard allows for outside housing temperatures! Big Grin

If you consider that an 'Audiophile' Ethernet switch has two main jobs, firstly to faithfully transfer the bits, and secondly to eliminate any noise from the nasty computer side of your system so it does not upset the delicate super clean audio side.

Anyway, this has come to light this week. It looks rather brutal, but in a foo-free and satisfyingly substantial way, although I am not sure if the welder was completely sober.

The DJM Electronics GigaFOILv4, snappy name eh?

I wonder how it might compare to the Etalon, Pink Faun and other similar items? (although the Pink Faun is a little smaller)

Hi Comfused,

If we worry about the noise from the computer side that might affect the clean dedicated audio device, will WiFi address this issue better? Because it has no physical wiring to the amp and Dac. And data packages stores on the local memory buffer anyway.

What is your opinion?

Thanks.

That is a big question, and something that I have seen as the subject of great debate.

In simple terms, wifi has the advantage of eliminating noise, either from the sending device, router, or the cable itself.  So in this respect wifi is best. 

Wired ethernet has the advantage of more robust data transfer, faster, less errors.  (zero errors maybe?)  If the wifi signal is less than 100% robust, which it often is,  there are likely to be lots of errors, the receiving device will need to work harder requesting "resends" of the data, thus creating noise at the receiving end.

To be honest, I am not an expert in this area, and in term of wifi experience I have very little.  I have simply chosen to go with the more robust wired solution, so I do not have any personal experience as to how good or bad wifi might be with a Devialet.  There are certainly others on this forum with more experience than me re wifi, and indeed more knowledgeable than myself re the subtleties of Ethernet protocols.  So maybe someone else can chime in on this issue.

There was a thread covering this topic once, not that I can find it now after a quick search.  Can anyone find it?

Hi Confused,

Yes I agree wifi might be requesting resend but the data eventually will come into the buffer before the buffer runs out. So I don’t see wifi will create any problem and it disconnected other type of noise from physical wiring.

I am still struggling in between use wifi or cable better for sound quality. When wifi is stable i personally can’t hear a difference but I want to know the fact.

Here is also an interesting article about cable:
