A thought: did you power up the LPS-1 first, and then hot plug it into the oM?  If not, try that.  I do not know how much capacitance the LPS-1 has, but considering it uses ultra caps, there might be a lot of capacitance, and this may take some time to charge up, so the LPS-1 might struggle a bit to meet the inrush current demands of the oM at power up.  Powering up the LPS-1 first, and then plugging it into the oM might do the trick.

 

Thanks Barrows,

 

Good shout. I did a bit of both and perhaps that explains some of it. Will play around again but only connect the oM once the LPS-1 has been green for a good 30 seconds or so.

 

PS Nice work on the oM. Liking what I'm hearing. Bit of a harshness or edge that I'm putting down to burn-in or sub optimal power supply. But on the whole a very nice crisp focused image.

 

Cheers,

Alan

Yes, sounds sensible at first.  The technical point of view for suggesting that the best power supply possible for the oM will make a difference is based on the theory that achieving the lowest possible phase noise from internal oscillator is critical to the sonic performance/results.  If one accepts that the theory is likely correct, then using the best possible power supply is likely to be an advantage, as clock phase noise is dependent on power supply quality.  I am just trying to present this in a technical sense, and am not making any proclamations as to subjective sound quality improvements with power supply upgrades, I'll leave those evaluations to users.  

On the importance of power supplies in general, one should consider that in most high end audio products with built in power supplies, the power supplies usually compose at least half of the BOM cost for internal parts, often quite a larger portion than that.

Great points, as usual.  You have offered a plausible explanation for why a better power supply so dramatically improved the ER.  I should make a better power supply for the OM a higher priority.  
 

Does Sonore’s 30-day return policy apply to the power supply you designed as well?

I do not really handle sales and that kind of thing for Sonore, so I really do not know anything about return policies, etc.  Sorry.  you would have to contact Adrian or Jesus to confirm that.

Did some A-B-ing to compare Ethernet vs Fibre into the ER and the Fibre sounds a bit crisper. Not entirely sure I think it's better. But crisper seems a good description. Think there is a slight harshness that wasn't there before tho. Giving it some time to burn in but think I like it already.

 

In my system, the oM settled in after a week or so.

I think that is my cue.  Well, the theory works in practice.  Very nice power supply (Sonore 5VDC for opticalModule).  Using with the stock power cords with excellent results.  And that is right out of the box.  It usually takes a while for equipment to settle in my system, but this already sounds very good. And the build quality leads me to believe this little brick will be in my system for a very long time.  Reasonable price too! 👍

That's the feedback was hoping to hear.  Thanks for letting us know.

Guys, today I use the Uniquiti Edge Roter X fiber output that is in a room, up to the OpticalRendu input, would there be any advantage in adding the OpticalModule after the Uniquiti?
 

I'm already feeding Ubiquiti with a linear source.

 

Another question, I saw in this topic a post that reports that it is possible to use singlemode gbic with multimode fiber, is it really possible?

The OpticalRendu will most likely perform at its best with a better switch upfront. Hence, it’s absolutely worth trying. 

Also, if that Ubiquiti is using POE, it’s not a good option.

No. Link please. The SFP is either SM or MM. A MM cable is different from  SM cable. Just google and, you will easily see how different they are. 
 

“The Singlemode SFP and Multi-mode SFP mean the SFP transceivers will work on different types of optical fibers; as in a Singlemode SFP will work with Singlemode fiber only, and a Multi-mode SFP will work with Multi-mode fiber only.”

O OpticalRendu provavelmente terá o melhor desempenho com um melhor switch inicial. Portanto, vale a pena tentar. 

Além disso, se essa Ubiquiti estiver usando POE, não é uma boa opção. 

 

Não. Link por favor. O SFP é SM ou MM. Um cabo MM é diferente de um cabo SM. Basta pesquisar no Google e você verá facilmente como eles são diferentes. 
 

“ O SFP monomodo e o SFP multimodo significam que os transceptores SFP funcionarão em diferentes tipos de fibras ópticas; como em um SFP monomodo funcionará apenas com fibra monomodo, e  um SFP multimodo funcionará apenas com fibra multimodo .”

Ok, I'll try it, Ubiquiti is not using POE, all devices on the network (modem, router and Wi-Fi) are powered by a linear sources.
 

OM works with gbic multimode, right?

Works with “everything”. SFP+ also. Singel mode is my recommendation. Yellow cable, with blue connectors. 

My recommended SFP’s. Tested with Sonore’s product line:

Unfortunately I can't test other fibers, my server is in a room far from the sound room and the fiber I installed many years ago passed through the conduits with great difficulty.
 

Another question, would the OM support use with a 12v source? I know the specs recommend 6-9v but I only have a 12v linear supply left.

NO!!! You'll fry it. 5v is best according to Sonore, but the other listed voltage will work (I believe I'm using my first gen at 7v at the moment with a Teddy Pardo LPS). 

 

Remember, voltage needs to be in spec, amps can be over but not under.

NÃO!!! Você vai fritar. 5v é melhor de acordo com o Sonore, mas a outra tensão listada funcionará (acredito que estou usando minha primeira geração em 7v no momento com um Teddy Pardo LPS). 

Eu imaginei, para testes vou usar um powerbank então, se for positivo o teste eu procuro uma boa fonte linear pra ele.

Sorry, I don't understand.

Desculpe, não entendo. 

I thought it wasn't possible to use it at 12v, I'm going to test feeding the OM with a 5v powerbank (battery) to see the results, if it's positive I'll buy a linear source for the OM.

…..well, you could set a resistor in series 😀

I asked my electronics technician for a solution, it will probably be what he will suggest.

One thing not mentioned is that the performance may be better as well if you can plug the opticalRendu and the fiber media convertor feeding it into different circuits. That way you really have isolation with the power. I was able to do that at our last house, esp as the network get was on one circuit, and the hifi on its own separate dedicated circuits. New house just all plugged into the same. But it's also my office system now, with fans, printers etc running so listening isn't as critical.

Uma coisa não mencionada é que o desempenho também pode ser melhor se você puder conectar o OpticalRendu e o conversor de mídia de fibra alimentando-o em circuitos diferentes. Dessa forma, você realmente tem isolamento com o poder. Consegui fazer isso em nossa última casa, especialmente porque a rede estava em um circuito e o hi-fi em seus próprios circuitos dedicados separados. Casa nova toda ligada na mesma. Mas também é o sistema do meu escritório agora, com ventiladores, impressoras etc funcionando, então ouvir não é tão crítico. 

Yes, that's the case here, the router that converts to fiber (to which I intend to connect the OM) is in a room far from the sound room, there are 25 meters of fiber between the 2 rooms, the sound room's electrical installation is separate from the rest of the house.
