This is not a valid test. Many good mic preamps will transmit
higher-than-normal noise when "unterminated," i.e. without a
low-impedance source connected.

To test the self-noise of a mic preamp, solder 200-ohm resistors from
each channel to the shield in a mini-stereo plug. With that plugged
into the recorder you'll hear a more realistic example of the
recorder's noise performance.
