Mixing!
Anything closer to the beginning of Hypocrisy - Fractured Millenium?
Just had a quick listen (through a crappy speaker) and that choir sound reminds me of Korg Symphony, an older sound module from 1988.. (Love it, tho' it's only mono!).
Might be something from a newer Korg?? Probably not that difficult to come up with, just layer with some strings and you're good to go!
