Looking to pick up some sort of Firewire based Audio unit that allows me to send balanced outs to my new powered monitors. I have been told Echo Audiofire 2 is the way to go... but figured you all may know/have something similar or better for that option. Eventually I will be getting a Intensity Pro card or Matrox system to have HD video out and want the monitors to be in sync with that as well. Going through a mixer from the 1/8" out on the mac pro did not sync up with my last intensity card.
