talking with my short experience
SM7b with: Triton, Solo 610, Pre73, old Rane ms1, Vtb1, Mic200 every with quieter voices, not music, only the voices and the preamp noises.
excuse me for the translation troubble about clear & clean, it's the same in my country: clear is flat, no noise with color or not, clean is no color, no noise.
a) rane ms1, 60 dB. No. clear very clean but low level.
b) mic200, unknow db's, the noise machine.
c) solo 610, 60 dB I think, mandatory maximum gain and output: excesive warm, little low level, but deadly clean (no noise)
d) vtb1 (maximum gain, no tube): clear and loud, good.
e) pre73, 65 dB's/50% output: loud but noisy.
Then with the triton boost (clean & quality phatom power mandatory).
a) rane ms1. SUPERB!! clean & clear, any that meant ANY noise or hiss.
b) mic200 the noise machine with noise boost.
c) solo 610: flat & clear, yes clear, good level, but unpleasent flat with triton (I think there is a impedance problem).
d) vtb1: superb! even you can use some distortion. the noise floor is little hight but it's good.
e) pre73: SUPERB! solved the high gain noise issue (over 65dB's) colored and deadly quieter.
my subjective preference ? 1) Rane+Triton for quieter deeper voices, Pre73+triton for the rest. For childrens, horrible screaming childs with theirs shrill voices
--> ever sm7+Solo 610 (without triton).
60 dB's are enough ? not for quieter sourcer, 65 dB's are more confortable, but CLEAN 65 dB's.
