This is completely wrong. Sorry to be rude, but such a statement
only shows your lack of understanding.

Then please point out the errors in the paper by Lipshitz and Vanderkooy.

I'm not saying that DSD is crap. It sounds well. But it doesn't meet
the claims set for it (as shown by L&V - you need at least two bits 
to have a 'linear' channel) and  as a storage or transmission format
it's inefficient compared to PCM. That means that if you use PCM with
the same number of bits per second as used by DSD, you get a better
result than what DSD delivers.
