I would argue that the difference in sound between the 458 (Speciale included) and an F12 is night and day.

The V12 sounds very musical and has a  "rich"/complex sound. The 458, to my ears, simply makes noise. Very subjective of course.

However, judging from the video, this new F12 version does not sound very different from a normal F12. Nothing like the difference between the the 599 GTO and 599 GTB in terms of sound.
