Schiit Yggdrasil -- 21 bit?


Schiit says that Yggdrasil is a 21 bit DAC. But the DAC chips that they put in the device ( Analog Devices AD5791BRUZ, 2 per channel) are 20 bit with the error of plus-minus 0.5 LSB.

How can the DAC be 21 bit if the chips are 20 bit? Using two chips per channel does reduce the RMS voltage of the noise by  a square root of 2. But how can you get to 21 bit from there?

Can someone please explain.

udishamir,
I would like to hear more about your impressions of the Soekris dac1541. Would you mind sharing?
It does. I researched them for a while but since it is new in the marketplace there were obviously no reviews. I ended up going with the Holo Audio Spring Dac but couldn't help but think for the money the Soekris represents a great value. Hope you enjoy it!
