Does anybody know of any amp designs playing PDM through class D GaN FET to loudspeaker? I have just found PWM variants, like Peachtree GaN-1 or Orchad Audio's Starkrimson. Why destroy the signal through PCM?

PDM - the most perfect of signals
A Pulse Density Modulated signal is a digital signal. But take off your glasses and it's analogue!
The density of the 1's is kind of analogue and can therefore be played through a LP filter. I'd claim this is the reason it outperforms PCM, PWM or any other signal.

PDM straight out using GaN is coming! Peachtree's GaN-1 and Carina GaN take whatever digital input, makes PDM and feeds the GaN amplification stage. Brilliant concept and therefore brilliant sound.

Reading the Wall Street Journal this morning I just have to lash out against AI again.
First the 100 hour workweek. We know the brain can't even do 8 hours by a computer in a day, all else is waste. Second, basing a business on Stars doesn't work. Third, simulations are not new.

AI benefits the ones already ahead:
"employees with more expertise ... are significantly better at accepting AI recommendations when they are correct and, more important, rejecting them when they are wrong."
Middle management could help, instead of elevating the "stars".

GaN transistors have caught my attention lately as they are not only making power supplies more efficient but also seem to have astonishing abilities in musical power amplification. So here's a comparison between Si and GaN in a 50W power supply.
