Then, how do you "describe" the difference in number of tones?  That is not
defined by density range.  All density range gives you is the lightest and
darkest tone...period  You could have an image that has ONLY the lightest
and darkest tone, and no intermediate tones...and then an image that has a
LOT of tones...both with the exact same density range.

It can take some audiophiles years to get "golden ears", as it take quite a
bit of experience to learn how to critically listen.  This is also true for
photography.

That depends on the print, now doesn't it?
