I'm thinking the same thing. Is it better $1900? If it was $750 it would be a no brainer decision for better sound during bad road conditions.
I usually dont' play music very loud and at normal volume. Is there a differents of clarity and able to hear the highs and low with base radio 90%?
In comparason my mother has a 545I with logic 7 which is not great in my opinion. Does the base sound similar to that?
