EtherREGEN: Installation, Usage, Difficulty, Questions thread

I thought the issue with the AudioLinux hacks was that they remove the ability to auto negotiate and force the NUC to communicate at 10Mb/s. Thus you have one stuck at 10 and the other stuck at 100. 

By hack, do you mean the Audiolinux expert menu choice used to control Ethernet speed?

 

This menu option uses ethtool to set various parameters. Any setting one likes, auto negotiation on or off, or various speeds such as 1Gbs, 100Mbs or 10Mbs can be configured from the CLI.

 

Left to default settings, AL will negotiate appropriate link parameters with the ER.

 

If you choose an unsupported speed, and disable negotiation, the ER is likely to have issues. Be careful, a little knowledge here is dangerous.

i currently use two Catalyst 2960 PD routers in my system with a similar configuration to what you recommend for the ER. This yields positive SQ benefits compared to just the one. I am about to buy an ER in the UK. In your experience and that of users, would there be any benefit to using two ER switches in my installation in the same way (so that one is also used as the “main switch”)? FWIW the system streams Quobuz to a Roon Nucleus with internal SSD to feed a Naim ND555 streamer/router.

Hello Ponkbutler--Not quite your case, but may be relevant.  I too have a single Catalyst 2960 feeding my system.(used to have an ND555).  I added the ER and things were better with the ER.  Also 2 switches better than ER alone.  I plug everything into the Catalyst (Router, Nucleus+, and Naim Unity Core) and then a single copper ethernet to the A side of the ER and then a single copper ethernet cable from the B port on the ER to the DAC.  This gives the best SQ.  Makes we wonder if 2 ER's would be better.  Using the stock ps.  TIDAL to Nucleus+.  No optical involved.  Router is 5 meters away from ER.  Using 1 meter BJ cables to connect all else.

I think you have previously asked me this. My answer was and still is that I have never tested the Keces P8 and can only go on what the manufacturer states. My suggestion was that you check the outputs with a meter to see if their zero-volt/-VE "grounds" are indeed independent of each other.


I will purchase an Allo Nirvana SMPS for the RPI in my DigiOne just to be sure and isolate A and B side consequencently. 

The Allo SMPS supports a ground shunt as yours and other tweaks (should sound like a LPS...). This should be fine for my RPI. The spare 5V out from my Keces is then used for my iPad to charge while „always on“ with Roon.

I have some measurments of how hot my etherRegen runs, between 47-48C and the cabinet is around 29C and stock PSU.

 

How did you measure the temperature?  Do you have a nifty gauge?

Hi:

While I am not sure of the cause of the problem you are experiencing, I can say with certainty that it is NOT a temperature issue. We torture-tested EtherREGEN units for quite some time at very high heats.

I'd like to know a little more about your Audionet DNP and what Ethernet input card it uses (their own design or perhaps licensed from Conversdigital or the Swiss company that used to be known as ABCpcb).

Can you do a test with everything on the 'A' side jacks of the EtherREGEN? Do you still have connection issues then? And are you certain that the new firmware flashed correctly (virtual drive disappearing upon copy is the only confirmation)?

 

Please keep us posted. Thanks.

--Alex C.

Hello Alex

 

Could you tell me the details of the temperature tests?  How many ports were connected? what was the ambient temp? how long did the test run? was music/info being transmitted?  What was the case temp?   I am having similar issues to Avalfa.

With a calibrated IR thermometer so I know it is right. I am not native English so the nifty gauge part what does that mean?

I was just asking what device you used.  You answered in your response "IR thermometer."

 

Thanks.

Running in the ER to a Sonore OpticalRendu for a friend...dang both of these get crazy hot in a non AC room so doing some passive cooling with a big heatsink over the 2 units...also helps hold them down.

 

ER is connected B-A(SFP) and powered by the supplied SMPS. OR is powered by SGC 7V 50W for now, awaiting shipment of the better Sonore powersupply and DC-4 cable. The B side is connected to another ER on the A side noted below. Final DAC for this will be a Denafrips Terminator

 

Another ER (my unit) is also in play, with A side connected via SFP to an FS.com media converter and B side to an Allo USBridge (sparky version) - final DAC for this will be a Denafrips Ares 2 or Soekris DAM1021 

 

DAC for both running setups are Khadas Tone Boards at this time.

Great idea! I had a heat sink just like yours sitting on a shelf. It was previously used for a wireless router that got a little too hot for my liking. Still has some thermal paste on the underside. Without reapplying any more I dropped it on top of the ER. It’s a perfect fit and definitely brings the temperature down a little.

Mine is also attached to the wall sitting on 2 10x10cmx1cm brackets behind one of my racks which is about 14cm from the wall.

Velcro is attached to the brackets and 4 2cm sq pieces of velcro are attached to the underside of the ER which keeps it nicely

in place. Air flow is almost on all sides and the ER gets no warmer than my LPS 1.2.

It aint the best looking solution but keeps the eR below 40C in a cabinet that is around 30C. Each heatsink is mounted with heat transfer tape.

 

I have the eR mounted on the wall and the cabinet is fan cooled.

Thank You for the picture. Will you please indicate the link for the heat sink. I will most probably move next year to a tropical country and I want to be on the safe side.

To be honest I dont know I have not used this kind of tape before.

Though I don't want to be putting holes in the wall for brackets, or gluing Velcro strips, I wonder if 2 or 3 Command Strips might work.

Hi Jud,

Obviously, the Command Strips have the advantage to be easily removed if necessary.

But as far as I can see the technical data lack information about the use as a heat transfer tape.

So I think I will follow octaviars´  way and order a heatsink being a bit taller and in the first step simply put it on top of the ER and see, what happens.

Best wishes,

Uwe

Hi Uwe:

I think Jud meant using those in place of screws to attach the brackets to the wall. Don't think he was suggesting Command Strips as thermal interface pads.

Wishing you a lovely holiday and New Years!

Hi Alex,

Sorry that I got Jud wrong.

All the best for you and your family as well.

P.S. The above shown heatsink weighs 2,6 kg. Would the case of the ER stand it?

Sure, the EtherREGEN case can take the weight.  But unless that heatsink is made of lead I have really hard time believing it weighs 2.6kg. That's almost 6 pounds for a 4-inch square, 1-inch tall piece of aluminum which is mostly cut-out with fins.

I might be made of kryptonite!  The nemesis of SuperDad

 

I would guess 150g.  Heat conductive tape is available on Amazon.  I would expect that tape probably isn't as good as thermal paste and certainly not as good as a conductive silicone adhesive.

 

Looks like I might get my ER in January instead of February.  Hope to be pleasantly surprised.

Heatsink on top my EtherRegen weight round 2 pounds, and work flaw·less! Made from pure cooper, keeping regen temperature

round 100F, with ambient room temperature 74F.

It is using thermal paste safe for EtherRegen case finish? Any tip for good one?

If you refer to the ones I use they dont weigh much it is just a small piece of aluminium.

As I have it wallmounted tape was the best solution to secure the heatsinks to both front and back. Some sort of thermal compound would transfer heat better but I went from 48C to 41C in a cabinet that is around 30C so I am happy with that.
