Indeed (I Googled) and it looks like it was introduced to the laptop line at that time, as well.

I've heard it said that inputting from 32 to 24 can lead to a more bit-perfect signal. How true this is I have no idea. I don't imagine it would make an overly large deal, doubtfully one you'd be able to hear.

 

If I remember correctly, the DAC just truncates the last 8 bits of data when it sees a higher bitrate than it's expecting, so, unless I'm wrong, trying to jam 32 into a converter running at 24 will not get you any sonic benefits.
