Yes, but do all these studies that conclude phase carries no or little
info also consider DIRECTION of source as relevant information ?
 
Such a study  could  well be looking for  only likeness to live sound.
If the reproduced-sound source in the  experiments was monophonic, for
instance,  then  directionality  is   obviously not  being  taken into
account.  It  would be  interesting  to see  what the  'conditions  of
study' are for such experiments.
