.....like a day and night different from first one tried, also much better than SMPS1200.
To be shure i not misunderstand, is the day and night difference between the two Connex from post 381/382 called "SMPS2000R version A Test with 2x5mF sec cap bank" and "SMPS2000R version B Test with 2x2,8mF sec cap bank". Thanks for teaser and congratulation to both LC and Christi for good result.
Yes, a day and night between the two SMPS2000R, named them A and B versions. As I can see the only difference is in secondary cap bank, maybe also something else, surely Cristi would have something more to say about them.
Anyway version B with Rubycons is an absolute winner up to now, doubtless.
SMPS1200 provided better bass than Cristi's A version, but that's about it, both Connex gives higher headroom, also more power because of higher and regulated rail's potential, at the end resulting in more stable sound imaging.
Not yet, have to test dual mono version with two DPS-500 first.
CONNEX:

AUDIOPOWER:
Thanks LC very exiting to follow your amp project. Looks like one is to consider Esperado's advising below and not rule out any of the competitors for other conditions/setups, i mean you and other listeners were very satisfied with SMPS1200 at prototype trials and at the exhibition audio show, and now another one performs better in your particular amp setup. Looking forward to setup results singing by 2xDPS-500Not yet, have to test dual mono version with two DPS-500 first.
Hi guys,
just a quick measure the ripple (photo not good, sorry).
LC show it better, no doubt.
Right you see the different behavior than a traditional smps Regulated.
apart from this, (please do not ask me any questions too deep) .. some i can for sure.
As you can see, there is no spike or others signal. (Probe 1:1 direct on output DC (no filter add). CH2 to DC rail.
11,8Amp at output continuos. (remember that DA version is 8A) consider also, I have only 470uF in high voltage cell.
Some will understand much more (with simple calculations eg. as the integral on the non-energy area,in relation to 10ms)
Nice weekend at all.
Roberto

Instead of being happy, some always have something to blame on me.
But... under what kind of "regime" is this thread? I have not forced the choice. What do I force?
I put my measurements , and LC puts his . I do not see any problem.
I have put measures that LC can do.
choose the battery charger of the iPhone for your amp, it sound well.

This is a vendor thread for lazy cat's amplifier, not for your power supply.
You don't see other people pushing their products on your vendor area.
You were asked to make a proposals for a smps for this amplifier and send samples. You did that already, so what you are doing now is called pushing, trying to convince with numerous explanations that you have the best product, when you have been told that this is unnecessary and Lazy Cat's testing will determine all this.
Nothing against you or your product and if LC determines it is the best option, then congratulations, but you don't see hypex and connex sellers posting everyday in this thread do you?
It just creates noise around the whole process, I'm not the first person to tell you this.

Nice looking picture. I just have few questions:
1. what you call traditional SMPS and what are the difference from your SMPS ?
2. what was the total capacitance connected on each rail both on board and external ?
3. how long you tested the smps output with 11.8A and what was used as a load ?
SMPS800RE and I'm considering to make a dedicated version for single channel FO to perfectly match the requirements of FO amplifier modules including the size and and shape of the board to fit into the enclosure which will be used. If there will be enough requests and LC recommends, we can go ahead. Dedicated version will be sold for GB members for special price.
Hello,
Measures are measures! I understand that it is better to use "words" instead of.
With "words", you can say anything without money investment, without study, without adequate instruments.
You are only able to put me, as Man pushing the product.
You've convinced me that the assessment would be "exclusively" transparent, and dictated by the real performance of the smps. But I have already said in this thread, how it would at the end. "one is good for two amps. the other is good for one amp".
This is offensive to my personality, and destroys the immense research work to get a smps as "The Solution" for high fidelity world. how can you think that all this can be justified to push 10 smps?
Participate in this GB, it is a big mistake on my part. What I want to achieve?
Regards
Hi,
Dear Cristi,I honestly do not know if you are a big ignorant in matters of smps, or you joke. (sorry, just from your kind of questions)
I call "Standard smps", it's like all the smps regulated, including your own.
You want me to describe your diagram, starting only from your own measure?
Or is better that you do it, starting from my measure?
...I do not try to find "chickens" but people able to understand!
Regards

I think that won't be so easy as may seem.
Look Roberto, as a result of your participation in this thread you are having your own SMPS GB for First One members, for which is OK, nothing wrong with that.
But, there is always some but, who guarantee those members that DPS-500 will sound right? Nobody, since sound representation difference between SMPS's are huge. As I tested the same SMPS2000R model, version A and B with minor modifications between the two, they are completely different soundwise.
My recommendation to First One GB members would be to wait and not buy anything before tested here. It could be a big disapointment and me personally will not take any responsibility for wrong SMPS choice from GB members.
Now Roberto please answer with simple yes or no, did you sent two DPS-500 already or not?
Regards Lazy Cat
From previous posts we have been led to believe that AP2 has sent the units to LC.
There is doubt - from the outset - as to the true position. [ From previous experience of Italian products (shipped from Italy) I know that things are often totally out of the hands of the sender until they have arrived at their destination]
So AP2, if you have sent the units, then it would be very sensible to send the courier's tracking reference to LC.

Hi,
First of all, I want to clarify that I have no problems with you, except one.
" You have not considered it necessary , to calm your fans , when they used words not appropriate to my personality. (does not matter, maybe I think in this way).
I have not tried to bypass you, (I'm very sensitive about this) my thread is started with the standard version of the DPS- 500 ( see please) . then , I have worked hard to change the standard version, and push it at 61V . not simple rewiring the transformer , but complex parameters , with full measurements .
I did this, solely to provide the opportunity , at the cost of poor smps , considering it takes 2 units. at end , only for 24pcs . or need DPS -500- S at 400 € .
Your pair of DPS -500 is in transit for your country , I want you to measure and listen in serious way . maybe one day , you will want to create a finished product in a high-end area , I 'm interested in this , as other companies are testing .
I also have another interest ... I want you to measure and confirm my measurements . it is absurd that someone thought that I can put false measures . An engineer is dead if it does this.
At the end , as you can understand , the DPS -500 or DPS -400 is perfect for all amplifiers , not only for the FO . sorry, but this does not depend on your words, but by all measures , including reliability.
-----------
This also means, that I hope your fans, do not buy the DPS-500, the reason is simple, they have no experience to understand the differences, therefore, can not appreciate the results. as they themselves have admitted.

Keep cool, AP2. There is no problem. Just wait for L.C had received your PSUs and published the results, both measurements and listening impressions.
It will be time, then, to publish your own measurements if you don't agree with the L.C. ones or indicate other methods of measure to achieve a deeper exploration if needed.
For now, what was trying to say MASantos is just that it it not clever to seem to push or influence the L.C. evaluation in publishing comments about your product (he will not be influenced by any words or photos). Neither to fight with Cristi.
Oh, man, when i was in my R&D office, my best friends were my competitors. Everything was making us kind of brothers: We were passionated in the same domain, we were facing the same kind of problems daily, and, as we were at the same technical level, we could exchange deeply on our researches more than with everybody else.
The fight was on the market level: prices, quality, communications, patents: not our problems.
Don't mix technique with business.Yes, AP2, keep cool. You have read elogious L.C. comments about SMPS1200, so you can have respect for Cristi's work. I'm sure he is waiting for the results of your SMPS tests to decide if he can have the same respect for your own work, as all of us
.This kind of comment: "Dear Cristi,I honestly do not know if you are a big ignorant in matters of smps" just deserve you.
Only winners, at the end of this contest: the losers will know in witch direction to go in order to improve their products. As Cristi knows now fore sure the importance of Elcap's quality, sound side ;-).
Friendly,
Christophe.
