I know, I know … like a broken record … but I maintain that the Yamaha AG03 is THE solution if you want to stream AND add a (phantom-powered) microphone with extensive EQ/FX/Compression options to your setup AND have a high-end (24-bit/192KHz) desktop usb-(powered) soundcard AND mixer with recording options (lite version of Cubase included) and have some extra redundancy when playing out as a mobile DJ.
I still consider it one of the best investments in gear I made in the last couple of years.
