In studio use only - u love this gear but am transitioning out of my tracking room. I've used this as an audio interface for tracking and editing in a B room, but Mai let I use this as 8 channels of pre. - the functionality is great and the sound is excellent- i used the heck out of the 2 channels liquid pres. - they sound great. Unit comes in original box with docs and a FireWire cable. Liquid Saffire 56 Get this: 28-in/28-out I/O. Two of Focusrite's Liquid preamps (each complete with 10 famous preamp models). Six more premium pres. DSP Mixing. How much? Not much, for all this awesomeness! If you're serious about your project, then you need to step up to an equally serious setup. You need the Liquid Saffire 56! The I/O count alone makes this amazing interface worth the great price. Add the stunning preamps, the DSP mixer/router ... BOOM.
