Hey guys, I'm trying to figure out the best way to get SDII, AIFF, ect. to my D/A's. Furthermore, I'd like to be able to use an IBook to do this. What are my options for external interface cards that have the proper computer connections and AES or SPIDF outs? I don't need more than stereo either. Should I just get a desktop and a soundcard? I'd like to know how the pro mastering guys deal with playback of computer files. I don't want to import digitally into my DAW, cause I'm processing analog on load in. Thanks.
