Don't get me wrong here, Harrison, I'm not saying shunt compensation is evil and wrong. I agree that both methods of compensation, shunt and miller, among others being discussed elsewhere are valid methods of compensation. I just think that shunt is more of a 'brute force' method and miller is more elegant a solution.
Hi student sound,
That is one very compact design . Some tracks need a bit of widening to carry the supply and output current . Thank you for joining the quest. Kindly give me more time during weekend to have a look at it just took a peek.
Hi Holgi,
Looking good. Could it be that you have followed SYMEF PCB Type1development . For 2DIFFET thermal runway should not be a problem. So only mosfets need to be on main heatsink. However if thermal/bias tracking is needed then the bias stage will have to be redesigned. Thank you for joining the quest. Kindly give me more time during weekend to have a look at it just took a peek.
kind regards,
Harrison.

@Holgi , nice PCB have you layout My not finished layout .......
Alex
Same compliments to you, Alex - very good layout, but different power supply strategy. I prefer reasonable onboard caps accompanied by litte 100n's directly at the collectors.
BTW: On first sight I thought you managed to create single layer layout without any wire-bridges, but then I saw and counted the 0R's

Let me start a tradition.
The first person to post their complete build of this amplifier and a review of it gets a token of $70.
