A 24-bit converter will accept the 16-bit dithered output inside of a

A 16-bit converter will NEVER let him hear the difference between the
dithered stream and the original 24-bit audio. Even if you are only
going to a CD, which today is increasingly unlikely, there is still a
good reason to have more bits to listen to.
Of course! But that wasn't my point. My point
was he should really be
using a 24-bit external DAC. Of course, it's more money...
As I said before, if the final product is going to be a 16 bit CD, you
need to be able to monitor what gets sent to that, complete with the
same dithering scheme that will be used for producing that CD. If it's
going to end up on DVD with more than 16 bits, then 16 bit isn't good
enough for mastering at all. Maybe master to 24 bits with 24 bit
moitoring, then separately test the conversion to 16 bits.
Certainly.
