Excellent.I heard from Aiyima that their TPA3255 PFFB based amplifier is coming soon.
Maybe to an extent, but not completely... TI provide details on how to implement PFFB using the TPA3255;i think people will say that whoever comes 2nd copied whoever was 1st to market
Normally Fosi do publish some early information in their products but don’t think I have heard anything about their PFFB product coming soon.Fosi seems to be working on it too, I don't know who will launch the product first, but I'm sure the price will not be very high. Looking forward to the test results and listening experience!
That TPA3255 modules with PFFB exist and have been tested. How they perform in a specific manufacturer’s sold product will be almost entirely down to the power supply.What isn’t a secret?

Aiyama, Fosi and so on use external power bricks to avoid the need to certify a “whole box” for AC safety. That’s fine but it does limit the power these modules can produce. 51V/10A is what the TPA3255 can work with, but you won’t see that in a brick supply!
The other significant point of difference between TPA3255 implementations is the output inductors - TI have a nice spreadsheet comparing them.
The point is, all these amps will measure the same if they have a good output inductor and power supply and are screwed together right.
I would assume more along the lines of A07 Max with probably slightly bigger size, Max has much better enclosure in every aspect than original A07.Do you think it will have the same case enclosure dimensions as the original A07?
