Okay, Okay, I'm really sorry for needing to post this. I've called and talked to the vendors, and I've been doing my homework on this for the past few weeks, but I'm having a hard time compiling anything worthwhile. I need to add a ProTools rig to my system, just for compatibility's sake. I don't want to replace my system, just get enough to make things transfer, I guess. I'm just wondering what the REAL APPRECIABLE differences are going to be between an MBOX2Pro and the Firewire 410 + M Powered PT, or the REAL APPRECIABLE difference between the MBOX2Mini and the MobilePre and M Powered PT. I understand that the pres and the a/d/a conversion between units will be different, and probably audibly so. Am I right? If so, how much? What is the REAL difference between M Audio's and Digi's ProTools 7? If it's something serious I'm not afraid to drop on the real deal, I just want to make sure that I'm not throwing money at something that I really only need as a platform. Thanks, guys, you've always been most helpful.
