I used to own B&W Nautilus 804, and currently own Focal Electra 1037BE. B&W's are pretty revealing. B&W's sounded thin when the front end sounds thin. With decent front end and amplification the midrange is lush and full. If you are using a receiver to power B&W's, I can tell you right off the bat that you will probably find the treble rather thin and harsh. I don't know about the Profile's, but Electra's have all the good virtues of B&W's, but they are more balanced, and have fantastic treble that is airy and free of glare or harshness.
