What would be nice is for these manufacturers to give the minimum input
signal level needed to achieve 0dBFS at full gain max sensitivity. And
the corresponding noise floor. In the case of the NH700 and RH1 this
is -66dBu and the corresponding noise floor is -116dBu in 20-20kHz for
the NH700. The RH1 is a tiny bit worse due to some 100Hz interference
from the OLED display breaking through but still pretty good. And
anecdotally much better that your typical midrange CF recorder aimed at
musicians, though I'd love to get my hands on one and measure it to
nail this down with measurement.
