Not too much really. It's probably not even worth the trouble unless S/PDIF can actually send more than 16 bits/sample. Using it with the ADC would be pretty much pointless.

But using it with s/pdif IS the WHOLE POINT.

http://en.wikipedia.org/wiki/Spdif says max resolution of S/PDIF is "20 bits (24 bits optional)".
Further reading here: http://www.epanorama.net/documents/audio/spdif.html

Example of a Micpre+AD that would match a 20 bit S/PDIF recording device:
"Denecke AD20"

I can't find specs for the S/PDIF input of the H1x0 on the wiki, at least before coffe...
But someone can probably tell us that it can handle at least up to 20 bits.

And making Rockbox able to handle more bits might possibly open for more interesting ports in the future. Am I wrong?

Llorean:
It's more "More interesting future ports might inspire Rockbox developers to make things handle more bits." If something's going to take a lot of time and effort that could go into improving something more useful to everyone else (as opposed to only useful to a very few people who have 20-bit inputs for S/PDIF) then often enough people will work on the thing where the work will be most useful (either to them, or to others).

You have to remember, people work on what interests THEM, not YOU. And usually this means things more globally useful. Meanwhile, you're also more than welcome to put in the work, as nobody would object to a properly formed patch I assume.
