Yes, the PA-4X "Liverpool choir" is even more direct and real, you certainly hear the massive sample data here. The Hmm choir in turn IMO sounds just like the "old" Roland one.
It's a pity Roland stopped advancing their expansion sounds in the same speed as in the late 90s. IMO the SN-A sounds are only partially an advancement. In the 90s they had, or at least cooperated with, Eric Persing... The old expansion series contained compressed versions of the sample CD ROMs Eric Persing had compiled.
