Welcome to the Forum, Rob! :T
Doesn’t really matter. Since you’re using a calibrated mic, you’d be better off going with a USB audio interface that includes the sound card, mic pre amp and phantom power, all in one package. The calibration for the Tascam US122 I’m using is down less than 2 dB at 5 Hz. I’m sure you’ll find similar capabilities with offerings from M-Audio, etc.
