I’ve spent a ton more money on other products and got vastly less improvement. These boxes are simply a no brainer. I’m really pretty amazed. Nice!

vortecjr Posted November 26, 2019 Author Share Posted November 26, 2019 Comparing the EtherREGEN to an opticalModule This is based on a recent post by John S: https://audiophilestyle.com/forums/topic/38968-etherregen-the-long-development-and-active-launch-discussion-thread/page/82/?tab=comments#comment-1007488 ER: The fact that there is a capacitor on the B side shield may be irrelevant. High impedance leakage (the type that comes from SMPS) sails right through the cap. oM: High impedance leakage (the type that comes from SMPS) can not sail right through the 100% galvanic isolation of the fiber optic ethernet output. ER: What is super clean and what is not so clean is going to depend VERY much on the system and how things are connected, again nosimple always works rule. oM: What is super clean and what is not so clean does not depend on system and how things are connected, again you will always have 100% galvanic isolation of the fiber optic ethernet output regardless of the upstream system. ER: If there is a way that leakage can get from something connected to the B RJ45, through the RJ45, through the external clock, then you will have a problem. (it won’t sound as good as it could, it doesn't mean it will sound bad, just not quite as good as it could). So lets look at how this can happen: oM: There is no way to have leakage current on the fiber optic Ethernet output.Therefore it will always sound as good as is can. ER:B side RJ45 High impedance leakage can get through the Ethernet connection whether it is shield connected or not. So if the endpoint is powered by an SMPS it can get through to the B side ground. If the endpoint is powered by an lps, the only way that can happen is through both end tied shielded cable. oM: High impedance leakage cant get through the copper Ethernet connection to the fiber optic Ethernet output because we have 100% galvanic isolation. ER: External clock: Any thing going through the shield of the external clock cable will be directly connected to the B side ground. So it depends on what is happening inside the external clock box. That you may not know. Again if it is powered by an SMPS there is the possibility that high impedance leakage could get through. If powered by an lps you can still have low impedance leakage getting through to the B side gnd. OM: We do not have an external clock input so no way you can have this issue. You can power the upstream devices with any PS you wish because we have 100% galvanic isolation of the fiber optic ethernet output. ER: In order for there to be a problem a loop has to occur through the endpoint and the external clock. Looking at the above it looks like if both the external clock and the endpoint are powered from a decent lps then there will be no path between them. oM: We do not have an external clock input so no way you can have this issue. You can power the upstream devices with any PS you wish because we have 100% galvanic isolation of the fiber optic ethernet output. ER: The BIG problem is if you have an external clock driving more than one thing, you could wind up shunting the ER isolation and creating a leakage loop through the external clock. If the other clock connection is to something connected to the A side (not just directly, clock to motherboard and regular switch in-between can still cause a problem) the leakage loop can cause modulation of the clock feeding the ER. oM: I have been saying to void doing this for some time now. Same comment as above no external clock = no issue. ER: Personally I would avoid using an external clock for anything "upstream" (on the A side) of the ER. It MAY be possible to come up with something for clocking an upstream device, but that is going to take intimate knowledge of the internals of the external clock in order to figure out if any leakage loops will form. oM: What he said...avoid the spaghetti. JS: So the general recommendation is to use lps for the endpoint and external clock, and only use external clock for ER and downstream devices. If you do this you can probably use a shield tied Ethernet cable between the B side and the endpoint. JR: So the general recommendation is to use a linear power supply on an opticalRendu endpoint and avoid the spaghetti.

You should connect your SonicTransporter to your router... You want everything else on the B side of the moat 👍 oM: Science fiction or science fact - Until John shows this hypothesis making audible contributions to the output of a DAC it's science fiction. At any rate you can't contaminate the ground of an opticalModule and send that noise to an opticalRendu endpoint. Why....because we have 100% galvanic isolation of the fiber optic ethernet output.

Cheers, I think your problem is the MC200cm. It says it is 10/100/1000 capable, which requires auto-negotiation, BUT the fiber protocol the oM uses is JUST 1000 only, it cannot auto-negotiate. This makes me think that TP-Link device is using an incompatible fiber protocol. John S. Link to comment
Axiom05 Posted December 24, 2019 Share Posted December 24, 2019 Did you try setting the MC200CM switch to Auto instead of Force? I replaced two MC200CM's with two oM's feeding my uR and everything worked and sounded great. John is probably correct that the two different units are not compatible. Try a second oM, you have 30 days to return it. The oM really is a better unit than the TP-Link one. soares 1 Main System: [Synology DS216, Rpi-4b LMS (pCP)], Holo Audio Red, Ayre QX-5 Twenty, Ayre KX-5 Twenty, Ayre VX-5 Twenty, Revel Ultima Studio2, Iconoclast speaker cables & interconnects, RealTraps acoustic treatments Living Room: Sonore ultraRendu, Ayre QB-9DSD, Simaudio MOON 340iX, B&W 802 Diamond Link to comment

What is the physics mechanism for THAT? 1st, what power supply are you using? If you can tell us the physics, that would be interesting! In any case, some thoughts on power cables, in no particular order: 1. The quality of the AC power at the wall is different in every home, and changes as well throughout the day, so we cannot expect similar results from different locations when it comes to power cable designs. These things will have different results in different locations. 2. Conventional wisdom suggests that noise on the AC is responsible for most, if not all, differences between power cables; in other words, different power cables act as different filters to noise, at different frequencies. Depending on what kind of noise is on the AC line to begin with, different cables will have different results. 3. The better the design of a given power supply is, the less influence a power cable should have on the sound, as a better designed power supply will be more immune to the quality of the incoming AC power (and the noise) than a worse designed power supply. This is not to say that even the "best" power supply will not exhibit some change with different power cables. 4. If we had "perfect" AC (which would be described as exactly 115 VAC, with a perfect 60 Hz sine wave with 0.0000% distortion) I would expect that any reasonable power cable (which is not actually "broken") of 14 AWG or more, which runs a reasonable distance from the source of the "perfect" AC power (say 6' or less) would provide as good performance as is possible. But no one has perfect AC power (a good AC regenerator, such as those made by PS audio are pretty close though).

Popular Post barrows Posted January 2, 2020 Popular Post Share Posted January 2, 2020 1 minute ago, Cormorant said: Barrows, keep in mind that I can clearly hear the basic characteristics of each power cord through a digital optical link. TRIPPY!!! Yes, I agree. The theory behind this which our design engineer John Swenson has is that the clock phase noise is the one type of noise which is passed along through the optical interface: this theory explains why there is an improvement in performance using the opticalModule (with its Femto level clock) versus a standard Cheapo FMC. So far this theory has not been proven (by objective measurements) but everyone hears the improvement with the opticalModule. Clock phase noise is very dependent on the power supply feed to the clock module itself, again, in the optical module we use an ultra low noise linear regulator to supply the clock power. So, if indeed it is the phase noise of the clock which is passed even through optical connections which is responsible for the differences, it would make sense to conclude that the noise of the power supply, and hence the power cable feeding that supply, could be "heard". I must admit, that these levels of noise are all so low, that it is very hard to believe what we are hearing! But I have yet to find any user who has not heard improvements going to the opticalModule versus a cheapo FMC unit. Indeed, everyone who upgrades the power supply for the optical module to our Sonore Power Supply reports a nice improvement as well. Personally, I use the Sonore Power Supply to feed the opticalModule, with one of our Sonore Power cables (made for us by Cardas) and it sounds fantastic. Although it is a bit maddening from an engineering perspective that these differences appear to be audible! jaaptina, soares and Matias 2 1 SO/ROON/HQPe: DSD 512-Sonore opticalModuleDeluxe-Signature Rendu optical with Well Tempered Clock--DIY DSC-2 DAC with SC Pure Clock--DIY Purifi Amplifier-Focus Audio FS888 speakers-JL E 112 sub-Nordost Tyr USB, DIY EventHorizon AC cables, Iconoclast XLR & speaker cables, Synergistic Purple Fuses, Spacetime system clarifiers.

Cormorant Posted January 2, 2020 Share Posted January 2, 2020 Barrow, nice post. I think the bottom line here for users of the opticalModule is to get a really really good power supply for it. And maybe a good power cable and even an audiophile fuse if you are so inclined. I would think the Sonore PSU would be an excellent choice since Barrows optimized and tuned it for the Sonore products. barrows 1 My system here Link to comment

Would there be an obvious sound quality improvement from selecting the Sonore power supply over the other two? Every customer who has used the Sonore Power supply 5VDC on an upstream oM has noted improved performance vs. any other supply they have tried. The theory for this goes as such: the opticalModule incorporates a femto level main oscillator for the Ethernet signal, and John Swenson has a theory as to why the upstream clock's phase noise matters. Many users report improved sonics when an upstream Ethernet clock is upgraded. So, then, clock performance is very dependent on having a perfectly clean DC power supply, inside the oM there is an ultra low noise, linear, regulator feeding the clock, but even so, the main power supply feeding the oM appears to matter as well. We have been selling a lot of these supplies for both oM users, and Sonic Transporter customers who are having the internal oM installed in the ST. Now, directly to your question: is the difference "obvious", so far I have not heard of anyone who has tried the Sonore supply for the oM who has not reported an improvement... On the other hand, only you can decide what is "obvious" to you in your system, and it would be presumptuous of me to suggest that this difference would be "obvious" to you. BTW, a little more about these supplies: They are hand built to order, by me, here in my Colorado shop. The 5VDC version is different from the 7VDC version (the 7 VDC version is designed to suit the needs of the Rendu Series), it is designed specifically to suit the needs of the oM (but of course will work fantastically for anything needing 5 VDC at 1A or less). This supply is fully linear in nature, with toroidal transformer, ultra low noise soft recovery diodes, high quality metal film and thin film resistors, high quality long life filter capacitors, and an ultra low noise, ultra low output impedance, discrete linear regulator circuit. We developed this supply to be as affordable as possible, while still offering near Signature Series level of performance, without resorting to Chinese production or mass production techniques. Everything is hand soldered to a very high standard. soares, AudioDoctor and kennyb123 1 2 SO/ROON/HQPe: DSD 512-Sonore opticalModuleDeluxe-Signature Rendu optical with Well Tempered Clock--DIY DSC-2 DAC with SC Pure Clock--DIY Purifi Amplifier-Focus Audio FS888 speakers-JL E 112 sub-Nordost Tyr USB, DIY EventHorizon AC cables, Iconoclast XLR & speaker cables, Synergistic Purple Fuses, Spacetime system clarifiers.
