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.

@shadorne and @defiantboomerang But JA also states "Now you could say that you prefer the sound of truncation against that of redithering and I have no argument with that opinion." Not to mention that JA’s measurement "suggest" that the LSBs of 24-bit data are simply truncated. So he is acknowledging he is not absolutely certain with his assertion/measurement understanding. |
JA is super duper diplomatic or euphemistic as always. Here is a five minute youtube that explains why dither is so important in digital audio. https://m.youtube.com/watch?v=zWpWIQw7HWU |
