Schiit Yggdrasil -- 21 bit?

@gdhal 
 
The Oppo UDP 205 is indeed outstanding and I expect that it sounds a bit brighter and thinner than the Yggy. It may well outperform the DAC3 as you claim. Perhaps the Oppo UDP 205 will be another Class A or A+ Stereophile recommended player. Per JA above, we can easily surmise why the Yggy is not.

@gdhal 

I'll up-the-anti. I'd like to suggest for the moment that you forget entirely about measurements. I don't care if its voodoo. The Yggy sounds spectacular. Please read my last post in the New Yggdrasil - First (and second) Impressions thread.

With respect, bro -- this thread started as a simple technical question and we have more or less arrived at an answer. Let's try to keep it technical.

FYI -- I have asked the manufacturer AGAIN about the 21-20 bit issue. Let's hope that this time they will answer.

I am very happy that you are satisfied with your Yggy. I don't share you enthusiasm and will never buy anything made by Schiit. But despite our differing shopping preferences, we can still have a reasoned technical debate about the 21 vs 20 bit question -- as long as we stay technical.

@defiantboomerang

Apologies.

I sincerely thought a wide degree of latitude would be acceptable, because your post (thread title) is specific to Schiit Yggdrasil, and it has been compared within this thread by others - directly and/or indirectly - to the Benchmark DAC 3. So, by extension, I thought - again, apologies because perhaps my thinking is incorrect - that since the DAC 3 uses a Sabre ESS 9028 chip, it would be reasonable to submit the Oppo UDP-205 into the discussion, because it too uses an Sabre ESS chip, albeit a 9038.

Please let us know what you ultimately decide to "shop" for.

My best guess to the 21 bit question is the utilization of the DAC chips in a balanced pair per channel configuration. Not that in any way changes the chips ability to process the data, but possibly lowers its noise floor to a degree in which they decided to market it with that level of performance, but not purely technical aspect of capability.

From what I have read about the AD5791 in use, its an extremely linear performing R2R solution accomplished by using thin film resistor matching, then placed in pairs to provide its performance in a compact and simple to implement package. It also exhibits little drift in variable temperature ranges. Other R2R products that have been shown in the market are utilizing FPGA processors running code that corrects the linearity issues of ladder dac in use. So as long as the linearity drift remains within a range, they can identify the error and correct for it digitally before it reaches the next stage. Obviously a lot larger and may not be as stable as the AD5791 in stability. 

@gdhal 

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