I just purchased a Firestudio Tube as well as currently own a MOTU 8 pre. The Firestudio Tube is a bit sluggish & has restarted my computer twice in the one quick recording session i have done (but is much better than my past experience with presonus restating every few minutes). My curiosity is towards the digimax FS but i have some questions first. What is happening when the Digimax goes through the 8 pre (does the Digimax handle all conversion & simply pass through the 8 pre or does it use the 8 pre conversion process (leaving the 8 pre "stamp" on everything)? I like the presonus sound better & will probably return the Firestudio tube in exchange for the Digimax FS if i can still get the presonus sound without having to deal with their buggy drivers. I like the idea of replacing the 8 pre with something better in the future & having the digimax plug write in. Oh & i`m using Sonar 7.01 for anyone who might be wondering Thanks ahead!
