Hi Vinnie,
I can confirm this observation as well after many times listening and comparing the 5G and 6G. The 6G has an audible uplift in the treble region, but is also less "harmonic", also w.r.t. its line output.
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.
