it seems like it has a warmth eq setting, like focusing on the low mids, not a lot of mids and focusing on just a part of the brightness to be just enough so the vocal don't feel muddy or boomy, and a room/ambience reverb that you can really feel and the a long plate or bright hall but quite. I think that's the key and to find a good vocal sample/loop

I'd try some pitch / formant shifting, and maybe some auto-tune. That should get ya in the ballpark. :)
