This is quite a big leap your making. As much as I like to promote Linux based pro-audio, you should make very sure that changing out your entire system like that won't cause you problems. >I am gearing towards an RME Hammerfall card >and a behringer A8000 adat interface. I would rather recommend buying the Alesis AI-3 if you want to use the ADAT interface. This gives you more freedom to use various preamps. (IMO, berhringer's preamps suck) If you've got money you may want to invest in a nice preamp. http://www.soundpure.com/browseProductType.do?id=5 -Reuben
