If you dont mind spending a few bucks more to get a firewire or combo laptop card adapter, the firewire audiophile is a much better choice because the usb one limits you in terms of the overall in/out choices. Lets say you do 24/96khz then you can only have ONE choice, analog in, out, spdif in, or out. If you use two or more, you will only be able to do 24/48khz for the channels.
With the Firewire you can simultaneously play/record 24/96khz with rmaa or whatever else.
