I found in actual use of a MZ-R30 that the self noise on a normalized 
recording was higher on the low setting. Because the level of the 
recording is lower on the low setting, it may initially sound better. 
But the proof is in the normalized recording. What you are really 
interested in is a ratio, self noise vs the sound you want.

You really have to test your individual setup. pulling out one piece and 
dissecting it may not tell you a correct story about the whole. It could 
be different for each mic.
