if that means what i think it means (equivalent input noise), and i'm 
not totally out of touch with the state of preamp technology, i'd say 
all but the 106, the 99 and the ? are bogus. and i'm not even sure about 
the 106 :)
i wonder who makes these figures up? or is there a legal way to doctor 
the measurements to actually yield such values without being sued?
