As for 'noise floor' much for example depends on the input signal, environment etc. or are you talking about the intrinsic 'noisiness' of pre-amps on the cited devices?. Maybe if you explain the situation/setup one could have a clearer picture. Anyway, because the SM57 is a dynamic microphone you should be ok with virtually any decent mic preamp: at an extreme limit you could probably even plug it into your computer's "mic in" (but then of course might as well use a 10$ skype microphone or something :) ).
