I know there are lots of these "success" threads, but this amp is a little different
As far as i can tell so far, it works perfectly.
Now i just have to build another 2 of them (i need 6 channels for active xovers).
There are two audio channels on this board each using:
SPDIF-IN -> DIR1703 -> PCM1798 -> 2*OPA627 -> 2*LM3886 (bridged)

An externally hosted image should be here but it was not working when we last tested it.

MWP, does the DIR1703 work fine?
With different sample rates?
It seams that the DIRs had a problem and TI took them out, no DIRs anymore.
It works fine with 44.1 and 48Khz without a reset between the change.
I tried with 96Khz which didnt work, but thats probably beacuse of the cheapie optical recievers im using.
Im glad i have a bit of a stash of DIR1703's here
