this looks more and more like a marketing thing.

Uhm.. somewhat agree on this. but my work is completed at the time that I put into production a product for third parties
---------------------------------------------------------
I want to share my research, of course it will not be easy, but I can assure you that a version of this amp, with input transformer, it will be posted in full in this thread,right for amateurs who want to listen to good music.

No , this is "bait and switch" . A BAD irritating thing.

Promise something , do not give it ..... creates irritation.

I can apologize for having anticipated the news ... but I do not agree that it can irritate. is not for sale, is a new architecture without a doubt.
when there were steam carriages, have killed Ford who made the car?

ok, switch the thread as limbo for now. after 50.000 module i show the research. what change?

With all due respect, AP2 is not obligated at all to disclose his technology to DIYers; now or at any time; especially with money riding on it, and for possible fear of copycats. I am anxious like the rest of you, and hope that AP2 will have patent protection.

N.B. Please direct me to your amp HB-300

Thanks to the intervention , I believe that music has not changed as when I presented the DXA- 400 . behind the attacks , the reason is always the same .
Patent pending and thanks to the completely new architecture , you can not change something and copy .
With pleasure, send via pm your email please, put some version of HB-300 300w(4R) integrated special smps.

Last thing I omitted. This new design also solves the problem of complementary devices . only works with N channel (obviously does not use an inverter as bjt ) . therefore , the " fantasy " of complementary devices , is better but only in theory , it's over !

TIM has also been resolved , linearity, transient , and linearity in dc ( some circuits , adjust the non-linear stretch of the mosfet in a simple way.
I have tested 120 mosfet (real measure) , linearity ( vgs Vs. Drain current is very bad ) even in the last mosfet audio products .
But it seems that the linearity in DC, and distortion , transient is not important.
I listen to only SIN @ 1kHz in my home , not music so it's perfect .😀

I have a few questions to the idols of the class AB:
Why , a huge current consumption to drive the mosfet ?
How have you solved the non-linear segments of the mosfet ?
Why pump a lot nfb ? you know that the fb adjusts the periodic signals ( and other things) but destroys the linearity of the transients ?
why a high DF ? ( aha , you not want , but becouse have huge fb, how reduce it now ? ) huh? .. suffice it to say that a high dumping factory is better obvius .
is better to have an input impedance close to the impedance of the output of all the preamp on the market , or it is better to have 100K ? ( Obviously they change the input cable , and feel the difference.)
Have you ever measured the output of the amp , with multimeter AC while he is near to the clip ?
has a few millivolts or 5-6 volts ?
I expect ( with sincere respect ) that an amplifier developed by one of the gentlemen of the class AB is simply perfect !

AP2, I looked at the thread on DXA-400 which coresta pointed out to me. I was impressed with its compact module which was shown. Your profile tells that you are an Electronics Engineer. I 've come to admire all of the talented innovators which emerge on diyAudio. I find it incredible how their minds work, and their productive output.

I vote for a Threshold STASIS class A/B power amp as perfect.
