There is an O2 user review on iaudiophile.net posted by D2 owner. OP basically says that SQ is identical, although he does not make any specific mention of bass roll-off. OP also basically says that it is D2 with a larger screen and no need for video transcoding, but sound from the videos is very weak (does not really specify what that means).
