Shots in the dark. The WM chip is a Wolfson Dac I think. The other two chips could be stereo chips of some kind or dual mono opamps?

yeah analogue devices chips, but I dont think they are opamps, they have 10 pins a piece, which would be an unusual number for opamps. could be something to do with EQ or a DC to DC converter to set the correct voltage for the signal to the dac. could be CMOS chip too. QA is probably just 'quality assured'
