Well, if you look at the specs it reads:
It features a carefully selected 12AX7 vacuum tube with UTC technology for exceptional warmth and lowest noise. Thus, the MIC100 can be used to eliminate the "dull" sound of standard digital recorders and sound cards. Also, it perfectly complements studio-grade condenser microphones. Dedicated Low Cut filter eliminates unwanted noise, e.g. floor rumble. .
All this verbiage really means is that it has anything but a flat response that you would require for a piece of test equipment to measure a room using REW. The HPF looks undefeatable, so your bottom end would be cut off; which may render it uncompensatable if attempting to include the preamp in the soundcard cal file.
You'd be better off with a solid state preamp that enjoys a flat response...
