A lot of this has to do with what kind of software you are intending to use? If you want to use Pro Tools, you'll have to have a Digi design enabled/capable audio interface such as the Mbox family of products. If you purchase a Brick, you'll be able to use any other kind of software but not ProTools.
And this product only has a single microphone input so you can never do anything in stereo effectively without adding an external pair of microphone preamps, since a single other microphone preamp won't match the one in the Mbox, you'll have peculiar unmatched stereo.
When you realize that Digi design is one of the world's most popular hardware/software companies, you know it's microphone preamp won't be crap, even though it was not an original Digi design product. What can you expect?? What is it that you want to have? The specifications are all quite good. These are all professional devices and their quality is more than adequate for anything that you want to do. Does it have the sonic signature you want? It's hard to tell until you listen to it yourself and also largely depends on what kind of music you intend to record. It's not easy these days recording an entire symphony orchestra with a single microphone input but was popular about 80 years ago.
