I did some measurements to find a cause, and I think the codec has some non-linearities:

Enclosed are some measurement pictures (Classic in red, 5G in blue), first frequency response of the headphone output, then the line output, and finally the step responses.

The measurements clearly show why the iPod Classic sounds less warm.

ugh, thats not very pretty... I think my little brother would love it though. I really wonder how the 1st gen Shuffle compares now.
