Premium Sound – does mp3 even make sense?

Hello together the missing MP3 capability of the Volvo radios as well as the lack of suitable retrofitting solutions has been and is here in the individual subforums already extensively lamented. Well another question: does MP3 or MP3s recorded audio CDs make sense in Premium Sound at all? Is the information left in the MP3 still sufficient to mix convincing Dolby PL II sound from the stereo signal? I tried out various audio CDs from MP3 myself and d I’m not sure. Especially with only 128kbps coded MP3s the stereo information is lost a bit with the “space sound”. With 192kbps the whole thing sounds much better. You always say that you can hear the difference between MP3 and “real” audio CD quality on a good system (I’ve never compared this myself so directly). Do you also think that this difference is reinforced by the Dolby ProLogic II mixing?
