NAD M66 Digital Preamp

I see the new M66 accepts a digital signal and does a lot of things in the digital realm like Dirac, crossovers and subwoofer management. My question is, the unit has 2 independent mains out, and 4 independent subwoofer outs. Does that mean it has a 6 channel DAC in the thing? And, are they the same DACs, or are the main 2 channels better DACs than the 4 sub outputs?
