That’s a funny synchronicity - I was talking with a friend two or three days ago about whether we should take something like this as a project, and I mentioned that mine would probably have one of the MiniDSP USB audio modules built in. I didn’t actually remember they existed until some weeks ago, and stumbled upon that particular model when I was googling for bare-bones USB audio stuff.
(Best use case so far, though: full-featured “hardware ORCA” with a 10" screen and built in MIDI I/O)
