Nice!

Thanks for compiling that! Should I be looking at more than 30? There's another price break at 50pcs, but I don't want to get stuck with extra boards.

Maybe 30 is a good start, and if there are others, then I can run another buy or let someone else give it a go.

Just to be clear, one board is enough for a stereo DAC.

Russ:

While I've got you here, could we go over a few things about grounding on the Buffalo II?

I'm just laying out ground planes / tracks, and I was wondering how the digital ground from the SPDIF input is tied back to the 5V PSU on the far end of the Buffalo. Should I run a solid plane from the SPDIF input on my board to the to the 5V PSU on my board (under the Buffalo), or should I run two smaller planes (one under the digital inputs, and one under the PSU) tied together by the Buffalo itself? I'm guessing the latter would be best, but I'm not sure what the grounding looks like on the Buffalo.

Same question for LGND and RGND. I'm guessing the best place to tie these two grounds is where they're already tied under the DAC on the Buffalo board. My L and R power supplies are floating for each channel, so that will be the only tie point between left and right. I'm also planning to tie the PSU ground to the AGND at the GND pin on the Buffalo for each channel respectively.

Any thoughts?

Owen

Only to be sure, one board is enoguh for a stereo balanced DAC?

Correct: One board = one stereo pair of balanced outputs using one Buffalo II
