great job....
looks good....

i could be wrong.....
i see one negative (i could be missing something).....

you don't have access to any of the test points on the rear, more importantly for the USB connection....
(i appreciate you still have access to the port)

So I've been working on your first setup for 24-bit with just the first adapter but it takes the GPIO pins that are used for sound that I would normally wire up to my Helder board. I notice in this one you have a pi zero instead of the 3, I know you said this is just for testing but in my scenario would you use a usb sound card to get around this? Been reading about re-purposing some of the the GPIO pins that look like they have Alt functions that do PW0 and PW1 but haven't messed with it yet.

I designed the adapter so you can still use pwm sound. It works on both pi zero and 3. On the Raspberrypi.org DPI documentation there are two ways to get 18-bit and one them doesn't use gpio18 and gpio19 which can be used as pwm0 and pwm1. You just have to edit the 24bit overlay and recompile.
