you make a very good case for the OPPO. Looks like a machine with tons of potential.

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, Hello, I was wondering if the Lynx card made any difference in the sound of Yggdrasil that you may have noticed or was it more so noticeable only on Soekris? Just curious being an yggy owner... |
I just found this post/quote from Mike Moffat and it appears to directly answer the OPs question. https://www.head-fi.org/threads/schiit-yggdrasil-impressions-thread.766347/page-123#post-12342937 "Two twenty bit DACs (one per phase) double the resolution for a balanced signal. Double the resolution only adds 6db (one more bit) for a total of 21 bits. In this case, 20+20 equal 21." |
