Here comes the €1500 OPTIMO 3 DUO with 2 separate LT3045-regulated rails @ 3A, available voltages should be 5V / 9V / 12V

 

https://jcat.eu/product/optimo-3-duo/

https://jcat.eu/JCAT_OPTIMO3DUO_manual.pdf

 

If 5V / 1.5A were good enough, then it might make sense to order 9V and then add DXP-1A5DSC (9V → 7V → 5V) afterwards

 

https://www.ldovr.com/product-p/dxp-1a5dsc.htm

 

Similarly, 9V / 1.5A is a better bet when we're adding DXP-1A5DSC (12V → 10.5V → 9V) accordingly.

 

As always the question is what we could expect from OPTIMO 3 DUO when compared to the latest DC4 Power Supply from Dr. Sean Jacobs as well as the legendary SR7 DR.

 Listening to what Sean told me about his new DC4, and price point, I think his will at top of the tree! Time will tell....

Mmmm?? What is different then any other lt3045 power supply? MP audio and ldovr.com
This is probably the transformer they use https://sklep.toroidy.pl/en_US/p/TTSAS0100-SUPREME-AUDIO-grade-transformer-TSAS100VA-voltage-to-50V/391

And six of +/- these  values

The set through hole is left/above the +out. 

 

 

@RickyV Did you get this board from Alexey? The board pic on his site does not show the Set through hole?

I think that’s an older pcb from before the paralleling idea.

I have one on order for a new server I'll be building. Exciting times in quarantine.

Contact Sean and ask for a price, price will depend what you looking for, 1rail? 7?

This makes the SR7 look like a bargain.

 

Matt

 

True

Spec for spec so to say, PH is much cheaper.

This was apparent when I ordered an SR7 last Dec.

[Also I wanted ready V/A for HDPlex 800W Converter.]

My SR7 should be with me within a week or two.

Even when it arrives I won't know how it compares with a SJ PS.

I agree all the favourable remarks about SJ - incredibly helpful when I enquired. I wanted to buy from him partly because he is only a few miles from me! But those prices ...

Further the SJ are rated 5amp, PH 10amp:-)

For 800W Converter this was material for me notwithstanding possible capacity of SJ Booster or whatever it is.

I think it’s fair to say you can’t call anything a bargain until you compare both, otherwise we would be saying the Innous Statement is a bargain against the Taiko Extreme! Would be interesting to see head to head! Until then I won’t be judging

One difference is that SJ's supplies are double regulated.  PH's are not unless custom.  You can add the LT3045 for extra regulation depending on how you spec'd your supply.  The need with an LT3045 is for a supply with slightly higher voltage, but not too high that it creates excessive heat.

 

There is no question that SJ's supplies are quite a bit more than even the custom PH supplies (not PH Design).  It has made me think twice and even three times before placing an order, which I have not done yet.

The Innous Statement was compared by stereophile not with the Taiko extreme, but with the Roon Nucleus +. Between the lines you could read that the Innous was worse. I wouldn't have thought so.

That’s my point! Until both reviewed side by side, you cannot say one is better than the other, or one os better value than the other.

It would be great to read first hand (inevitably subjective!) reviews of two products against each other like for like. But there's not many of us that can do that whether we are talking about expensive servers or expensive power supplies. Meantime we make purchasing decisions: 1) rationally based on information we *can* garner - combined with 2) our intuition about how a product might meet our personal needs and expectations. Naturally price gets factored in as 3).

 

Is anybody likely to have an SR7 - preferably DR - and also a new SJ DR - for an "all things equal" comparison any time soon.

Even the SR7 DR is about half the price of the DC4 and has about the double amp output of the DC4.

Yes, I own an SR7 with DR and Paul agreed to build me another custom SR7 which I have not executed for the lone reason that it could be 2 years before I see it and even then I may never.  I waited 6 months for mine and I thought that was a long time. I keep an eye on that build calendar thread and it's not positive.
