First: studio recording of acoustical instruments result in music registrations
--what's your hangup with 'concert hall noise floor' as being in some way
relevant with such a registration? Self-noise of competent microphones is below
20 dB SPL, eg. AT 3035 - a USD 200 job - states 12 dB SPL eq. noise level
Close miking just about anything will quickly get you in the 110+ dB SPL
range, so a 100 dB range is possible for sure. Of course this also depends on
the lowest acoustical level attainable from the instrument/environment .
Directional microphones / noise gates, etc. are used to minimize mechanical
noise,
if necessary.
The master recording's dynamic range can, depending on composition, etc.,
very well be in excess of 90 dB.
I believe it was dbx claiming a 100 dB requirement for the recording of
acoustical instruments' performances.

Second: many types of music don't use acoustical instruments, or exclusively so,
yet also do not start out as amplified music, so another strawman there noted.
Electronically generated signals can have pretty much a dynamic range that
is limited by the electronics used, that is *well over 100 dB*.
