  1. I have mentioned in one of my previous posts, but I did compare an LPS-1.2 with a 1.5A Sean Jacobs LPS. I compared several 5V devices (JCAT, Allo, USB reclocker, etc.), an ultraRendu, and a NUC that was able to run from the 12V on the LPS-1.2. In most tests the LPS-1.2 was charged by sBooster. I liked the SJ a little better in every test I did. I consider the LPS-1.2 an amazing device with genius engineering that also sounds really really good. I am not sure why the SJ sounded better in my system, but the larger transformer and big Mundorf caps may very likely have something to do with it. It's also more expensive.
  2. me too Yes, sorry, I misread your message. Does it say anything in the manual what each is used for? I haven't used a motherboard like that yet. Have you checked with a multimeter if the DC+ on one of the EPS connector is connected to the DC+ on the other? It seems like you may need (benefit from) 5 rails for a motherboard like that. Yes. Good to know. For my next project I may try multiple R-core transformers (one dedicated for each rail). Sounds like that would be a killer LPS. We, DIY-ers, can afford one-off exotics like that from time to time. It would be more difficult in a commercial solution where so many things need considering.
  3. Let me clarify something. Sean did not do that. It was a DIY project I did. I used his regulators and recap modules and placed them the way I described (similarly to the way it's done on the Statement). I ordered a large transformer by his specs for this project. I wanted it to be massively oversized and the best build quality. As far as I am aware Sean does not offer what I have done. It's a tedious job to mount and wire everything. It's not that complex but takes a lot of time to do. I use one 12V rail. Although you have an 8-pin connector, four of the pins are the DC+ and the other four are the DC-. I mean they are paralleled on the motherboard and are not separate inputs. At least that's how they are on my Asrock gaming motherboard. I think the reason they use 8-pins instead of 4 is to end up with a higher gauge wire when you combine four parallel wires from the power supply to the motherboard. I respect you and John a lot, just from the posts I have read. And I would never even try to go against anything John says about that stuff. Not to argue (don't really want to do that), but to provide another perspective. I had an argument about a R-core transformer (that looks very similar to yours on the outside) with a DAC manufacturer. And I tried his transformer. To make a long story short, his R-core transformer worked better on his DAC, but not on the computer (seperated in a different chassis like I have described earlier). One of the differences was that while his transformer was oversized, it was still much smaller than the toroidal I used. And the toroidal I used was much more expensive, had electrostatic shield, GOSS band, and every trick in the book to reduce noise (some of which might have been done on the R-core too). This does not tell ANYTHING about YOUR "R-core" transformer, but it convinced me as an end user (not a manufacturer) not to look back. Also, given that the power supply I use took about 3-4 months to completely break-in, one probably needs about 6 months of parallel running to determine the true performance of each transformer. I did not spend 6 months on this test, so take my word with a grain of salt. But for me, I am sticking to the oversized toroidal.
  4. He does not own Innuos. He just designed their power supplies. His company is called Custom HiFi Cables - http://www.custom-hifi-cables.co.uk/home/power-supplies/dc3-power-supply
  5. Exactly. As far as I am aware his DC3 power supply with Mundorf caps is identical to what the Innuos Statement uses. If there is any difference (other than the custom transformer of course), I haven't been able to spot it. Way better! But as far as I am aware he is a one man shop, and hopefully he would be able to handle higher demands if it ever gets there. Not sure what you are referring to.
  6. Yes, you can buy a custom LPS from Sean Jacobs. That's what he does.
  7. Maybe - I will consider that. In the meantime if anyone wants to know more, just send me a PM. Happy to help with whatever I can.
  8. The Critical Mass footers are expensive too. The small model (suitable for the SE) is $1,000 for a set of three. Some dealers were doing buy 3, get 4 promotion, but still it's much more expensive than the isoacoustics OREA. The OREA is hard to beat in terms of bang for the buck. But the Center Stage are a lot better. I think you get what you pay for in this case.
  9. I don't disagree at all... Hence my comment about diminishing returns... Everyone has to find that point for himself/herself. I believe the SE scales pretty well with power cords - but again one has to find the point of diminishing returns. I made a big mistake by trying a Hurricane on my server. It was a big mistake, because I could not go back to my previous power cord. I hate when that happens (my wallet does at least, my ears are in heaven). So I stopped trying random things that are beyond my budget.
  10. IMO, Critical Mass Systems Center Stage footers and an AudioQuest Hurricane (FireBird is even better) power cord would bring your SE to another level of performance. But that's the point of diminishing returns for most people.
  11. Let's talk about the SR7. Yes, SR7 is unobtainable. I have never had a chance to try one. And I probably would never do. Sometimes I wonder if the SR7 is really that good or it's the fact that people can't get it that makes it so desirable to the point that it became legendary. There is a very small number of those power supplies ever made, and yet so many people talk about them. I bet most of those people, just like me, have never heard one in their system. So let's not split this into a thread of people with SR7's and everyone else (aka mortals). And let's not say that the only alternative for the mortals is a NUC solution. There are other power supply alternatives. Sean Jacobs at Custom HiFi Cables is a good example. He has learned a lot from his work with Innuos. In my opinion, the way the power supply on the Innuos Statement was designed might be even a better approach than using a SR7 with long umbilical cords. Here is a good article explaining the distributed design on the Statement: http://www.the-ear.net/how-to/power-supply-design-innuos-statement I am OCD when it comes to that stuff. I have a Sean Jacobs power supply. It sounds a lot better than the sBooster, LPS1.2, etc. in my system no matter what I power with it. A huge excellent quality oversized (400VA) toroidal transformer is a key part of it. I have also gone the Statement distributed power supply approach with the transformer and the recap modules in one chassis and the regulators in another chassis with the motherboard. I have 4 separate rails going to the motherboard (3 for the ATX connector and one for the CPU). My cables from the regulators to the motherboard are between 1'' and 3''. They are 15.5AWG Mundorf Silver/Gold - https://www.partsconnexion.com/MUNDORF-72180.html. Expensive but really good. Every wire has the JSSG360 shielding, even those that are 2'' long. Yes that requires soldering, but attention to every detail pays out. I have heard the difference between having a long wire from the regulators to the motherboard and a short wire. I can also hear a difference between the different types of wire I use there, no matter how short they are. Amazing stuff, and to be honest if someone told me those little things make a difference I would not believe that. So, the question is if someone can give me a SR7 with two rails, would I replace what I have now? I would have to install a Pico DC to DC ATX converter and use one rail for the ATX. And another rail for the EPS connector. And use 1 meter long cables for that. I don't know. Actually, I highly doubt it. There are too many compromises in such a solution - the long umbilical cords, the shared DC rails, less DC isolation, all that cross-contamination, the DC to DC converter, etc. I would certainly try it if I had that chance. But my point is that the SR7 is not a perfect solution either. The transformer in the SR7 is half the size of the transformer I use. And no, I did not just get a big transformer from eBay, but an expensive custom one made to order with every trick that can help reduce noise and lower the impedance. The Mundorf capacitors Sean uses look a lot bigger and better quality than those on the SR7. Yes, the SR7 uses a magical custom regulator, that is supposedly the best in the world, but can that make up for all the other compromises taken here? Maybe it can, maybe it can't; I don't know. Sean Jacobs is just one solution out there. I am sure there are more. It just happened that's the one I am familiar with. I suggest instead of splitting this thread between mortals and immortals we go out there and explore the current solutions on the market, try, test, listen, and report back our findings.
  12. cryoed compression springs? First time I am hearing this, but why am I not surprised :) I think your microRendu is the weakest point in your system. I had the ultraRendu powered by sBooster and LPS1.2 for a long time in my system, and I can say that some of the computer solutions discussed in the "big thread" here sound so much better. Way better! An Innuos Zenith sounds a lot better too. The Statement is even better but comes at a much higher price. IMO, changing the source would make a much bigger difference than some of the DAC upgrades. I can't comment on the Optical Rendu as I have never listened to it. But I would highly recommend you try one of the computer solutions discussed here (you would have to do some reading in the big thread if you want to go the DIY route) or a commercial server solution like Innuos.
  13. Yeah, Turbo Boost is an Intel technology. The Ryzen 2700x has higher TDP than the i9-9900K I am using. You would probably need more than 5A. Haven't tried it and can't comment really.
  14. If you turn off Turbo Boost on the i9-9900K, 12V/5A is enough for the CPU. If you want to use Turbo Boost, I would recommend 10A. I also have 3.3V/1.5A, 5V/5A, 12V/1.5A DC rails going to the ATX connector.
