while i must say im continually impressed with the sound of the firestudio, everyone is right to say the drivers suck. nowhere near as stable as the firepod. random crashes when cpu gets intense, and problems with my daw recognizing it if i fire it up with the daw already open, unlike firepod.
though i gotta say i only paid 350 for the firestudio, while the ff800 is what, nearly 2000. for that price......i dunno, tough call, especially if you upgraded pres for the firestudio.
