Actually, the OPA690 choice was based on KurtW's amp (he used AD8397s for left and right and OPA690 for ground, except that his amp's "ground" is a OPA690 acting as a rail-splitter, and no separate output ground channel). Kurt reported good sound and lower battery comsumption as compared to AD8010. I have yet to test any of this, pending the arrival of prototype PCBs. So, I am just operating on blind-faith here, and won't know whether the OPA690 would be the final recommendation until I build several prototypes with different chips and test them all.
