Default Purifi 1ET400A Measurements

Audio Science Review has posted measurements of a (pre-production?) sample of Purifi's upcoming 1ET400A kit. According to the site, DIY modules should be available in Q4 2019.

Looks like marginal improvements over NCore, more interesting talk on exact model prediction, technological modeling using Matlab compared to brute force calculations, furious amount of marketing .

At what price point will this come at, I wonder.

There is another product on the market, but the person who developed it as a developer of marine military radars and audio amplifiers for special orders, so not many people know about him. However last years car on his SO amplifiers beta version 2.1 has gotten 4th place in EMMA sound competition. (subjectively marked down because car was from Russia )

Any way, first time since developing from 2014 now he finally decided to go public and develops V3, it is almost complete now, I'm waiting for pre orders to start. He said that pre-order platforms and website will be ready in few weeks.

His 2.1 beta version was already much better speced than any of Hypex and still better than Purifi. While price was about 180 euro. V3 is based on no compromise components policy, so will be more expensive - looking at 280 euro with Balance or Digital input.

That about as much as I know about his Indra Amps v3

I can believe, (even the subjectively marked point you make) its pretty clear vast amounts of esoteric of control theory influence lies in Russia its not the first time I hear this.Would be interested to hear where Putzeys gets he's research from.

I would not wish to be misinterpreted if I stepped in and gave a shout for Putzeys but 'wondering where he gets his research from' makes it sound like he is ripping someone else off. I often rip off ohms law but sometimes have to be slightly more insightful when I combine it with other stuff.

As for 'esoteric control theory originating from Russia' and the unknown designer working on marine military radars I'm sure the marine mammal fraternity think he is a bit of a dick and ISTR the original designer at NuForce worked on Tomohawk Missiles and managed to produce something that was unhappy with certain loads.

Having said as much it might be better to properly link to a product rather than leaving us to guess. Perhaps yoodog can consolidate his cherry with his second post to the forum.

Thanks. Missed that. He did pop in about the 5th and suggested he would return.

here is the thread. Old version of those amps got 1st place on all car audio competitions in Russia in top class SQ and came 3rd on final of EMMA CarAudio. New version is on the verge and is now being built on no compromise ideology.

?????????? ????????????????? ????????? (soAmp) Oriel Indra - ???????? 11

Guy who developed those is navy defence radar developed who sells his product to China and some other countries for costal defence

he never has time so I'm trying to make it interesting fort him to complete it asap. Can't wait for those beasts to be complete
