I think the only pioneering improvement on the Lab 5 (which is -technically- virtually perfect) would be the implementation of a real-time ABC, like the Visionclear system for TVs: every time you open a door, close a window or draw the curtains, the bass level readjusts itself within seconds, instead of calibrating the speaker only on customer's demand by pressing the top plate.
That should keep B&O engineers busy for a few months I think..
Reunion Island is greeting you!
