The discussion about this is stopped ten years ago by a master thesis
from the german university of music in Detmold, how has a highly
reputeted school for audio engineers. The thesis itself is in german, 
but here:
http://old.hfm-detmold.de/eti/projekte/diplomarbeiten/dsdvspcm/aes_paper_6086.pdf
is a translation to english. The summery begins :
"These listening tests indicate that as a rule, no
significant differences could be heard between DSD and
high-resolution PCM (24-bit / 176.4 kHz) even with the
best equipment, under optimal listening conditions, and
with test subjects who had varied listening experience
and various ways of focusing on what they hear.
Consequently it could be proposed that neither of these
systems has a scientific basis for claiming audible
superiority over the other. This reality should put a halt
to the disputation being carried on by the various PR
departments concerned."

The original paper is here:
