Excellent news.

 

[Guddu]

From Aiyima's link - Loads of features, and better frequency response in audible range (probably because of PFFB).

*** I guess sound impression might be neutral to a touch warm, specially with 6/8 Ohm speakers.

Cool, price wise seems very competitive, power is ballpark with the 3e module, this with a less powerful PSU.
The gain switch is a nice surprise, my rough calculations tell the gain from xlr is just 17db, maybe a bit more. being able to increase it to 20 dB is a nice feature to have.
The disappointment is as usual having a low pass filter instead of a high pass one.... I wonder why they always do the same, is it so much more difficult to implement or is it not to hurt the measurements? I would trade 10db Sinad for a high pass any day in a secondary system. But I won't complain too much, the millions of people out there with passive subs will appreciate it .
It would be good to know how they define the filter frequency, the graphs in their web suggest lower values...

PS: and I hope it becomes easier to buy. I ordered 3 a07 max from @AIYIMA AliExpress shop and only one arrived. I gave up and ordered from another seller, crossing fingers this one arrives.

Very strange choice of subwoofer cut off freqs… and I’m thinking it doesn’t apply a hpf to the amped speakers? How is that not a basic requirement… gimmick added for people who don’t know better

What measurement is this?

I can see that the main amp's measurement below is nice, so what is the upper graph?

If the performance measured by Amir is this it will be a great coup, however guys, you really need to put a designer in the company.....

It's wonderful when a company experiments with new designs. Why don't you include tone controls?

It's wonderful when a company experiments with new designs. Why don't you include tone controls?

By adding the treble and bass tones, the signal will pass through the treble and bass lines, which will lose the original sound quality， but you can adjust the treble and bass tones through the preceding tone,

 

[Talisman]

This is something I still don't understand, it seems only SMSL has figured out what it is for. Neither Fosi, nor Sabaj, nor Aiyima implement a HIGH PASS filter for the speakers, which is much more useful than a low pass for the sub, the active subs always have their own integrated low pass filter, we are not interested in filtering it upstream, I I use subs with a normal line output for example.
Why these low pass filters? Who are they for?

 

[Talisman]

By adding the treble and bass tones, the signal will pass through the treble and bass lines, which will lose the original sound quality， but you can adjust the treble and bass tones through the preceding tone,

This is why the vast majority of "classic" amplifiers have a "pure direct" button to allow you to choose whether to use the tone controls or exclude the filters from the signal.
I really appreciate the implementations you are making and the way you are responding to customers, but if you really want to start presenting a complete product it is time to think about products that are not just a power amplifier with an analog attenuator attached
