He's saying the warmth and slam are inherent in the TI/Burr-Brown multi-bit chip, not that it is inherent in the top 6 bits themselves.  And then he claims that using Delta Sigma for the lower bits gives them the "smoothness" that is supposedly inherent in DS.  So marketing can thus claim that they get the best of both worlds by using a hybrid approach! lol

 

So, this begs the question, do TI/Burr-Brown chips have warmth and slam?  Also, does Delta Sigma inherently have smoothness?  And  can combining approaches actually give the desired qualities of the two approaches?  And what ratio works best?

 

Now, if the different chips in themselves produce a different sound, I suppose it would make sense that whichever approach handles the highest bits would have the predominant effect on the overall sound, so their approach would then have more "slam and warmth" as a result of having the TI chip "on top" (that is, if these chips actually have such characteristics in the resulting sound).  Having the "smoothness" effect added by DS handling the lower bits, on the other hand...perhaps they have done extensive blind testing which has shown that smoothing can be increased by 4.8% while only reducing the "slam" by 17.1%, which was the optimal compromise, resulting from their chosen ratio of bits for each approach.  Originally, they had tried having the TI/BB on the bottom, with DS on the top bit only, but that resulted in reducing slam by 94.3%, which obviously didn't please any of their test subjects.  Additionally, DS on the top for any number of bits greater than one had the dreaded effect of adding at least 3 veils for the first additional bit, and increasing exponentially from there.

 

Bear in mind that the above are simply my "theories*" on what occurred in their blind testing (which they may not have even conducted haha), as I was not a participant.

 

 

*aka, "wild ass guesses," which have as much in common with actual theories as anything in audio marketing speak.
