I have owned the 803's and I listened to both the 803 and 804 extensively before making my decision. The 803 is not only fuller in the bass, it presents a better midrange as well. The 804 seemed brighter because of the comparative fullness that the 803 has in the midrange. The 803's are worth the extra $1500 or so depending on your dealer.
My sugestion to you is to listen to the ProAc 2.5 before committing to either B&W. A much easier speaker to listen to long term.
