Audiozen, I can guarantee that the noise floor is not going to define the sound quality of any preamp, once it has gained acceptable levels. But excessive low noise floors do make me suspicious. A more important quality might be how the equipment reacts to a signal rather than the lack of one.
BTW, I could not listen to any of the preamps you mentioned- I like music to sound natural, for the equipment to not draw attention to itself, which is a failing of most of the brands you've mentioned so far.
