As noted in an earlier post, the M-Audio MobilePre is an el-cheapo USB preamp interface. But I had to rely on that for some trial recordings.
Using a Maxim mic, laptop sound card noise floor is around -50 dB
M-Audio MobilePre with Maxim mic noise floor is around -60 dB
Using dynamic mic - Ahuja ASM-780XLR - results were similar.
Nose floor rises to -40 dB when capture slider increased to 80%.
The XLR input on the MobilePre seems to be defective - S/N almost unity! -18 dB of noise
