I have to agree with WATYF...man it really sounds good, and it's great music too.
I'm a drummer, and I've always wondered the best ways to record drums with a DAW, running through an multiple input/output sound card such as your Aardvark DP 24/96. In my case, I would be running through a mixer and then into the sound card I would assume.
I see up above that you said you used Acid for drums? Excuse my ignorance, but what is Acid (if you get my meaning...)?
