Thanks for taking the time. I was thinking that no sonic improvement might be the case but wanted to be sure. I used biab to play back tracks only. Everything else in mac realated apps and pro enough for my needs. Although one day I like a few channels of something from Cranesone or Appogee. Those were hot when I was putting my recording stuff together.
