I don't recall exactly what I sent to this forum though I may have sent 
only the main file because I suspect this was at fault. I sent my GO 
colleague a whole batch of files including the releases I later 
suspected to be the real issue and he confirmed they were. I now used 
Sony's Soundforge to batch process one set of release files and sent him 
a specimen to check if the issue has indeed been addressed by what I did.

How these files turned out so different I have no idea and the person 
who would have been able to answer the question is no longer with us to 
do so. So we've got to sort out what he left behind the best way 
possible. If the batch process I chose ie bit-depth converter, selecting 
24 bit instead of the default 32 that shows up on the window, works fine 
then the matter is solved and another lesson learnt.

For all its worth, this is the link to sample problem file (one of the 
releases that is being implicated and yet to be corrected):
