There's not much to say right now except, do not buy a Sabrent USB Soundcard if you plan on using it with a condenser microphone (BM700, BM800, NW700, NW800, NW1500, etc.) They changed the audio chip inside which dropped the voltage pass through by 1.5v causing a huge decrease in performance. Some people have even claimed that their microphones don't work at all. So please hold off on buying this if you're using it for a condenser microphone.
NOTE: It should work great if you are using a DYNAMIC microphone that requires no voltage. I still think it's a great option for that.
