Yeah, mostly DDA, and some songs are live mixed on the console, this is DAA then? Anyway.. :-)

I think the real shift to digital was around 1994-95 when professional digital recording equipment became somewhat affordable even for smaller studios. My Roland DM-80 4-track digital hard disk recorder, you also find on the albums webpage, was more then 20.000$ back in 1991, so most studio easily stood with 16-tracks on analogue tape.
