What's a good sound card for multi layered song editing eg. Sonar etc.

what would be a good sound card to get if i want real high quality sound, and like super layering. i don't remember the word for the "layering" but i remember there's only a certain amount it can handle, like 64 or something.

Would it be "voices" by any chance?
I highly recommend Creative's Audigy series, but I have also heard good things about M-Audio sound cards.

yeah it is voices lol thanx. i use sonar 5.0 and i can't playback with sonar because of the "voices", because i have onboard sound, so i have to playback using synthfont...
