If i understand right your Proceed dac board with separate L/R dacs does not work and you intend rebuilding it using a stereo dac, correct?

Why not just repair what you have? Have you got a scope? Can you verify the L/R splitting is working and the dacs get the expected inputs? Are you sure the board gets correct input?

Building a new board can't increase the resale value by much.

Probably not. The OP would be better advised to fix the original board as the PCM1710 is incompatible with the DF1700.

With equipment this costly I would repair restoring the original situation.
Also much better for the second hand value.
