Hey everyone -- me and my friend record rap music, and for the past year or so we've been currently using the Samsung C01U USB Studio Condenser Mic. An enormous improvement over the built-in microphones on his computer! Just plug in to the USB port, and it's ready to record. But we're looking to upgrade. We're almost 100% positive that we'll be purchasing a Shure SM7b, but seeing that we've been using USB microphones for the past year, we have no idea on how to go about setting up a professional microphone. From what I understand, the Shure SM7b is a dynamic mic so it doesn't need any 'phantom power' -- correct me if i'm wrong. Will we just be good with something like the M-AUDIO Fast Track USB (http://www.m-audio.com), or should we get a soundcard like the E-MU 0404 Digital Audio System Pro Soundcard (http://www.musiconmypc.co.uk/product_info.php/products_id/164). In other words, besides the microphone, what else would we need for a good setup for a crisp, professional sound? Keep in mind that we don't know exactly what it is we need -- we're just looking for a good setup! Budget doesn't matter at the moment, but we're not ones who are ready to spend thousands on equipment either. Thanks!!
