I own Dali Helicon 400s and they have no problem placing instruments on a soundstage. They are not the most detailed speakers around but I prefer them to more detailed speakers I've owned like Audio Physics. They're more musical.
SACDS and DVD-As seem to draw tighter more separated images than cds. I don't know if high res downloads do the same though.
