normally I prefer cards as I don't like the low-end rolloff on *many* hypers...makes them almost too bright/thin sounding, though, I am a fan of thick punchy bass.
there are definately instances where hypers are called for/needed(me thinks I missed 1 such instance at STS9 this past weekend). imo, I think wrong placement/config makes people like hypers so much...example:
how many times do you see people running X/Y when a quick visual look at the room/mic placement SCREAMS DIN or ORTF? they often end up with a (relatively subjective) muddy, mono recording. instead of changing configs, they change the caps?
the recordings quality seems to improve so the taper thinks the cards arent as good.
