I own a dvd-a player (by default; I just liked the dvd player) but if I was going to choose which one I wanted based on the software, I would choose SACD. SACD seems to have more current and classic rock than dvd-a. I have a real hard time finding albums I like on DVD-A and the fact that a lot of SACD's can be played in regular CD players is an enormous advantage IMO. Can't comment on sound quality because I have only heard one format.
