I’m in contact with the developer and with person who has installed his first gen amps and got first or second places basically in every single or car audio competition in Russia and nearby on them - to be fair SQ is extremely popular in Russian car audio, there are at 4 different international formats that take place in and around Russia (Ukraine, Kazakhstan and some east Eu countries even) + he participated in the only big EU car audio competition Emma and got great results on his system when it was not even fully set.
About developer background. I just shared what his background is, because his head working is something I have not seen in my life - if you ever saw passion and professionalism working together than you know what I mean. I have been waiting for 6 a while for him to complete his v3 now and it seems like he did it finally
I will be happy to share more info once avaible, but that is all I have for now. Oh new amp name is Indra v3.0 as far as I know
I went to the Russia thread but could not understand anything. Can you tell us more about the amp? How good is the performance, is there any measurements?
Thread is very old, there was no interest, no conversation till now.
It looks like V3 is still a car amplifier. There are CAD 3D drawings. Balanced input on the front, output (?) on the back. It is a modular system of mono blocks, you can attach as many modules as you like side by side. It is no clear how battery power is distributed between modules. For the rated 250W, power speakers impedance should be less than 2 Ohms. (?) 600W version is on the cards.
Claiming 95% efficiency, but radiators look hudge. No module dimensions, no more specs. It will be built in Europe, so possibly shipped from EU?
Full documentation (including schematics) is promised to be published when pre-orders start.

Can you elaborate Reactance?
If you mean that suggesting other brand SMPS has some "commercial" incentive, please be aware that we almost live in 2020...
Nowadays, social media like audio forums are also platforms to do business.
How many examples for this way of doing business happening here outside the so called commercial sector you want?
This is a technical thread, so all technical suggestions perfectly allowed.
I'd rather be more interested in why a Cresnet (with supposedly better quality components) would improve on a Hypex (or whatever brand) SMPS.

It would be appreciated if alternatives to the Hypex SMPS1200A400 were linked. The more they are available the better for everyone. Surely there are some designed and ensambled in Asia too.
Then each choose according to their criteria and comment on impressions and, better yet, measurements. At 115 Vac (more amperes) and 230 / 240 Vac.

Hypex power supplies are expensive for a reason, I wish I owned one, but I don't, and wont bash.
They are slightly more expensive because.
- International EMI and Safety standards.
- The solder work is very good, wave-soldered the component joints are sturdy.
- Design although traditional TL494 with magnetic synchronous rectification, solid engineering, rugged, simplicity over vanity. (I think Nand Eeckhout was the engineer behind the SMPS in collaboration with Bruno at Hypex).
- Components are good, not sure why you claiming its cheap parts, again I think they source parts from reliable genuine sources.
- A plant somewhere in Malaysia assembles it with very good attention to detail/QA control.
- Idle power is ~5W.. TNY274 used for standby.
Its an expensive business to sell at high volume and keep the lights on. gotta respect this.
At 115 Vac, with Hypex NC500 mono ensambled by Nord.

Reading this, Maty might have a point:
PSU 101: Capacitors Manufacturer Tier List
Su"scon capacitors are among the worst category....I'd expect Hypex to use better quality components to begin with, the more so because heat is the biggest enemy of electrolytic capacitors.
Capacitors on these Hypex supplies are located next to the hottest places, which are the semiconductors. Not so good engineering IMO.
Another (major) reason for a more expensive Hypex SMPS is that this is audio business.
I am pretty convinced that you can find at least the same quality for less money (or better quality for comparable prices) when checking mass producing specialized SMPS manufacturers.

come on guys, we do not pay attention to what members did in another forum, so do not bring that up here....pulled two posts with such theme....not allowed here...Well, why are the Su'scons capacitors inadequate? Would other capacitors be better? Also, yes, on some builds there may be a heat buildup, but that's the purpose of using proper heatsinks or ventilation (I have a Noctua fan on my raspberry, half a meter from me, and it is inaudible).
Another alternative, in case one wants to same some money, are the Connex power supplies.
Think of Behringer, we all know that it uses low quality components but his products are cheaper accordingly.
In EU, for only € 169 + shipping you have a class D amplifier, with low SNR.

I am confused. Does this Behringer sound as good as a Hypex NC500 with a Hypex SMPS?
