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?
Could it be that EIN refers only to theoretical quantization noise of
the units? I didn't run that calc.
I'm also suspicious ~120dB equivalent input noise, presuming the sign
of that number is negative. Well, with either sign the number seems
fictitious.
