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.

+1 to Dave and defiantboomerang seems more and more like a troll each passing day.

Well, I too would have to believe there is more to why someone would purchase a DAC 3 over a Oppo if sound were the primary consideration.

Im using both the Yggdrasil and the Soekris dac1541 which is true R2R.
The Yggdrasil soundstage is phenomenal, i do however notice that mainly in electronic music the Soekris sound is more crispy and enjoyable.

udishamir,
I would like to hear more about your impressions of the Soekris dac1541. Would you mind sharing?

Sure,

Its a very interesting DAC, its form factor is really appealing, its compact with an excellent sound quality. I must admit that before attaching it to the Lynx AES16e sound card (was using direct USB connection) it was OK, didn't "blow me away" (also leaving it working for few days does the trick). 

When connected with the Lynx sound card, then everything "opens up" started to hear new elements (especially in electronic music, soundtracks).

Soekris is a Danish company, i got the DAC two days after i ordered it (i live in California), They are very responsive.

My previous DAC was the Marantz HD-DAC1 which is a Delta Sigma, great sound for its price but beyond compare to the Soeakris or ofc the Yggdrasil which is a Monster, seriously. 

The Soekris is cheaper then the Yggdrasil and give it a fight :)

I personally recommend !

bellow is the dac1541 spec:
