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.

I ’think’ it even sounds better if run with a source prior to a listening session, even if is left on all the time (as mine is).

Not sure if I could reliably tell either way - maybe it’s my own little placebo... :)

A question for Yggdrasil owners: do you still use the stock power cord provided with the unit or have you substituted another cord?

I substituted the power cord immediately. I also removed the very 'basic' footers.

Robert Harley is the one who reviewed the yagdrassil dac, he is a very good and accurate reviewer, for Absolute Sound....

I'm using the stock power cord.

Hi David. Were you able to detect an audible difference with either the (ones you use in place of stock) cable or footer?

I'm sure you read the manual. The Yggdrasil has "zero stick-on feet (because Yggy already has screw-in feet—you’ve reached the big leagues now, guys)" 

Just a little humor :)
