:lol: I've used 001 for a couple of years now. The last computer I built to specs reccomended by pro tools enginner staff at there webb site. Still unstable at times, I'm wondering if that version ever really worked very well. I'm thinking of getting the 002 rack. Any comments ? Can you hear an improvement with the A/D's ? and higher sampling rate ? Does the fire wire help reduce system overhead thus making the system more stable ?
