So I'm working on a setup, but I'm not interested in spending thousands on a single Neumann tube mic. To be more specific, I've been deciding between a Mackie Onyx 1640 analog mixer board, and the M-Audio Projectmix I/O hooked up to a Mac. In all honesty, a digital board linked to a Mac (or PC, *blegh*) and Pro Tools is just as powerful as any analog board. The only (obvious) limitations I see are the fewer amounts of I/O on your average digital board. That, however, isn't an issue for my applications. As far as Aux Sends, Direct Outs, etc., all of those can be controlled through a digital board's controlling software. I can assign 8 channels of input to as many Aux channels as I would like (so long as my CPU doesn't freak out). So what's the deal? Why should I invest in an analog board when a digital board can do all of that, and more?
