Final post on this thread for me:

take a 16/44.1 file into Audacity
make a copy, reduced by 6dB using Audacity's 24-bit level function
(this mirrors an SB acting on redbook audio)

diff the two

result: <6dB of white noise - exactly what theory predicts due to
reduction of SNR

keep going, lowering the level further each time...

12dB reduction = <12dB of noise
18dB reduction = <18dB of noise
...


So, no "loss of bits", "loss of resolution","loss of music" or any
other effect - just the predicted decrease in the SNR.

So, 24-bit digital level control is transparent except for SNR.

This really is just as well because of course this is exactly how every
mixing suite, mastering suite, DAW etc does level control (be it @
24/32/48/56/64 or 72-bit!).
