Yes, personalities abound in these forum threads. And yes, folks have what one might call “signature statements” that amply showcase their strengths and faults.
From what I can tell reading posts is that not a lot have actually personally heard this newer GaN-FET tech implemented into a class D audio amp design. So while the likes of AGD, Technics and Merrill might in principle sound terrific based upon this newer tech based upon the tech’s inherent theoretical advantages, they may also suck in real world implementation due to other designs flaws.
I’m not saying that they do suck and that the older MOS FET tech operating at lower switching frequencies are still king of the hill in class D land. But one ought to be careful in proclaiming one design implementation dead based upon merely theoretical considerations of a newer FET tech design.
