Here are the specs for the Focusrite
   If you "Focus" on the EIN number, this measures the noise. Here the
   figure is -120dB, and it needs to be in the -128 to -129.5 range, if
   properly measured, (budget gear is never properly measured, so add a
   few points).
   What this means is that when you add the noise of the mic to the noise
   of the preamp, you get, well, noise. Not a lot of noise, but noticeable
   on a lute recording. Why the noise? Well, one reason is that it is
   powered by the USB bus. USB really does not have the power to run a mic
   preamp on a budget system.
   dt
   Frequency Response 20Hz - 20kHz +/- 0.1 dB
   THD+N < 0.002% (minimum gain, -1dBFS input with 22Hz/22kHz bandpass
   filter)
   Equivalent Input Noise (EIN) < -120dB: measured at 55dB of gain with
   150I(c) termination (20Hz/22kHz bandpass filter)
   Gain Range +10dB to +55dB
   Max Input Level -3dBu
