I think what you're missing here isn't just the increased cost of the DAC chips involved, it is also the cost and time to develop the digital filters required for these chips.
Then there is also the case of whether or not the audio manufacturer has the "chops" to be able to even design the required filters.
Taking something off the shelf and slapping it in a case is much faster as well as cheaper.
That said, even though companies like Linn and Ayre use delta-sigma DAC chips, they put their own filters in and by-pass the built-in filters on the chips themselves; this may be why they've gotten such a good reputation for good sound.
Take a look at this post from Mike regarding the Digital Filter/Interpolator/Sample Rate Converter in the Yggy, it sheds some light on why everyone isn't doing what Schiit is doing

Hi and thanks a lot for the very helpful advice.
So the real secret of the exceptional sound is in the proprietary digital filter implemented ?
What i do not understand then is why they do not put more efforts in developing better filters.
I give up and wait for the future.
After almost 30 years from the birth of the cd, this sector is very far from to be mature IMHO.
Thanks again. gino
