Who, in your opinion, makes the most reliable audio interfaces with trouble free drivers on the Mac? I am a ProTools LE user and I want to start using Logic or Nuendo to edit and mix 5.1 surround for film & video. I need an interface for monitoring 6 discreet channels that is reliable and is from a company that supports Macintosh with timely/reliable driver updates. Digidesign is not the model here. What I DON'T NEED is expensive mic preamps for recording because I will never be recording with this interface, most interfaces will have preamps, which is ok with me, but the quality of them is not an issue for me. Low or no latency is necessary and I don't want anything that has miniplugs for the analog output. I'd prefer not to spend more than $450. My machine is a MacPro 8 core/2.8 Ghz. I am considering the following usb interface, but I've never heard of the company. They claim it works using CoreAudio and doesn't need additional drivers: http://www.esi-audio.com/products/gigaporthd/ Anybody use it? Thanks a million for your help.
