Gallium

I blame GUTB, I was happy with the sound of class D and inexpensive gear until he pointed out their flaws.😀

Cheers and accepted, in 2018 we had a series of threads where everything sucks, posted by GUTB, lol, I do miss those threads. I use numerous class D amps in the house, our Yamaha UPS-5600 has class D, as do the other sound bars, my Fender Rumble 100 is class D and having listened to class D blind next to class AB I couldn't tell the difference!

Peace

One of the main criticisms of Class D is that it must suck b/c the amps switching frequency is too low to produce a true audiophile sound. These amps work at a much higher frequency and so supposedly solve that problem. 

 

Another benefit is the ability to switch much higher current flows with Gallium based semiconductor devices - that is fueling the R&D (power conversion for PV panels, batteries, EVs)

 

Not sure, but I think Ga might allow a device to operate in Class A for a much greater time before moving to Class B... so you could use a Class A amp to drive something besides a horn or a headphone

 

OTOH, maybe Benchmark has obviated that need with their licensed technology

Thanks Chris and Ralf.  Whatever y'all decide is fine, I just wanted to own my fail.
