The 7323 Bitstream chip incorporates the digital filter, Bitstream DAC, and analog output stage. Audio Alchemy has chosen to bypass one of the 7323's analog stages in favor of a single Analog Devices AD746JN dual bi-FET op-amp, shared between left and right channels. (The first op-amp in the 7323 is part of the switched capacitor network and can't be bypassed.)
