500W (4ohm) GaN Class D Modules - Starkrimson Ultra
tmazz:
Leo I have heard you previous amps and have no doubt that this will be a great sounding piece. However while a 500W amp would have done a great job pushing my big Theils , it is just way to much power for the small monitors I am using now. So for that reason alone, I would have to say that something like this would not interest me.

Update 12/29/2020:
The layout is finished...
I had to make the board 4.85 by 3.75 inches to add some additional circuity, due to feedback that I received for the other board.
Added LED to indicate over current
Added LED to indicate overvoltage
Added LED to indicate that board is powered up
Still need to do final checks before manufacturing the boards. However, the layout is at a good point to start getting quotes. So please let me know if you would be interested in getting one or two of these.
The board will need the following power supplies:
+/-36 to 42.5V for power stages
+9 to +15V for Driver (referenced to -36V)
+/- 12 to 22V for analog sections
A single Hypex / SMPS1200A100 provides all of the required power supplies. and can power two modules to make a stereo system.
In simulations, this amplifier achieves over 98.5% efficiency at 500W.
