Square wave looks excellent. What is the amplitude?
And do you mind to share more info? Schematic? All I can see is 3 pairs of big Sankens 😉

looks very impressive ...
You should perform some test that include both resistive and capacitive loads
i like the regulated front end above rails from the output stage and i also like the thermals as seen in the schematic
It looks like a very well designed amp from the first look
Kind regards

Nice design, close to a typical high end Marantz. Maybe you should post some measurements and PCB layout. The square wave plots are impressive.
You could try to use 2 pole compensation technique to extend loop bandwith and lower THD further.

The square wave is not impressive ....it is simply expected from a design like that..... while the problem remains how the all thing will behave under load .
You know ...high speed amplifiers with astronomical bandwidth is very easy to make then the next question will be stability Obviously you will eventually land to something lower to gain stability and load tolerance

Hi Veysel
I like your work and much better your first results.
do you plan to make GB the boards ?

Nice work-
I think it would be good idea if it would b possible to use ON semi power transistors.
Several project DIY-ers chose MJL4### over Sanken.
