DSD uses a delta-sigma modulator, which is an adaptation of delta
modulation, which is distinctly different from linear PCM.

As far as I'm concerned, you embarrass yourself with each counter-post
and contradiction to these known facts. I don't need your agreement to
know up from down and black from white; this is as far as I'm going to
go in this thread.
