Avid Pro Tools + Mbox Pro
It's time to get serious about your interface. If you want to make professional-quality music, you're going to need a rig that can step into the ring and deliver. There are two way to do this: you can spend a ton of scratch on a load of gear and figure out the details from there, or you can just buy the right gear the first time. The Avid Pro Tools Mbox Pro IS the right gear. You need amazing converters and killer preamps? The Pro Tools Mbox Pro gives them to you. More specifically, you get a whole set of 24-bit/192kHz converters that smoke many of the standalone converters out there, and four amazing preamps that have all of us wondering how in the heck this interface can be so affordable. No joke, no exaggeration - these freakishly quiet and transparent preamps are so good that it simply doesn't make sense.
