The noise floor of a well-made recording is on the order of 75-80 dB.
Below that is the noise floor, usually from analog (thermal) sources.
This is many times more than is required to properly dither a proper 16
bit conversion.

I'd be interested in seeing data on the noise performance of studio mics
and preamps, etc.

Neumann TLM103. Equivalent noise floor of 7dBA

Dynamic range of the microphone amplifier (A-weighted) 131 dB
