Thanks Oliver... I think we all appreciate the effort your are putting into this!

By the way, I need more shunts , but more plusses than minuses. In total 3 positives (+19v, +15v, +12v), and one negative (-19v). You did not perhaps have some single positives lying around, do you?

Alternatively I can get some from Quanghao, but would be nice to fit them all on the same stack...

I have the TDA1541A shunt module and the +5V signle shunt module here.

Doedes SPDIF board works with Olivers TDA1541 board, but his USB board does not. For the second one you need the buffer.

Doede's USB board works fine with Oliver's TDA1541 board if one omits R28 and R31 from the latter. Well, that's how I got them going . . .

Sorry to be dumb but what does a high-speed buffer do that a normal speed one doesn't?

it's fffffffffffffffaaaast

Does M2Tech Evo need this ?

So what's the science behind that? What do R28 and R31 do?
