Many dac chips today offer a balanced current out. Practically speaking, many among us only need unbalanced out. One thing I don't like that much about the D1 is the need for a costly output capacitor. Could I simply add a INA134 balanced to unbalanced converter after the D1, bypassing the output caps ? There's a possibility to null offset with the ina134. Matching all the parts of the I/V stage would in theory make the offset rather low.
Something obvious I'm missing here before I order the parts ?
