I don't know about such things in the audio world, but in the world of 
color photography, most professional digital equipment uses 48-bit 
color. This is way outside the reproduction range of any photo 
printing/display technology. But even though a particular 48-bit color 
might not be printable or displayable, it is still there. It can be 
taken into consideration when doing color adjustments and image filters. 
The end result is that when color depth is reduced to the 24-bit color 
range that JPG uses - you get better and more accurate color reductions.

So I would think that working in higher bit-depths for audio would 
similarly result in better sounding audio when it's reduced to CD format.
