No. And there's a reason.

Every I2S DAC board , that's made for working with an ARM board would IMO have be able

1. to slave the ARM board with its own Master clock to achieve best results or
2. it would have to properly reclock and isolate from the transport

If that's not the case I'd rather prefer a well done USB DAC (e.g. ifi Nano DSD).

Let me know if there is any DAC board out there, that would meet those requirements and wouldn't cost more then a 100$ total.

Why is it every comment/thread about raspberry pi seems to get hijacked around here!
I think the pi is fine for audio. It has to output I2S - hardly in need of huge amounts of RAM and CPU speed.
If you're happy with your USB and more powerful PCs then great. Do they provide any extra challenge in power rail filtering with all that extra noise?

(If you're at all interested, this project actually achieves point 1 from your list, and probably could be made for less than $100 if you wanted, but it is completely DIY, handbuilt. - what with this being a DIY forum 'n' all)

At the moment, most of my attention is going towards refining the I/V stage and PSU for that - very little attention is given to the Pi at the moment - it just works and outputs I2S. I've not had a corrupted SD card for about a year (you really should be shutting down properly).

I also think I need to rebuild my headphone amp, because it's clearly not keeping up with this DAC.

Zoran, I've since noticed your comment. You're right, the I2S has to be converted to feed the PMD100 correctly. There's a thread on that somewhere. I knocked up a board to make that conversion a few years back, and am using it here. It's based on Guido's circuit over on diyhifi.
I suspect the kernel driver for I2S could be modified to output in this format, but what I have is working...
