I want to buy a mic to use with the IPP - looking at the blue spark and shure mv5 and shure mv51. I'm primarily going to be recording music. I'd consider any mic really, those were just the ones I've been concentrating on. I understand that I won't be getting the same results as I do with my desktop setup and I'm not looking to. I have never used a usb mic with iOS and want to get the best mic I can for 200$ or else. Any opinions would be greatly appreciated!!!
