B&W Sig 805 vs 803D vs 802D

I currently have B&W Signature 805 speakers. I love the midranage and especially the clarity and openness of these speakers. I just auditioned the new 802D and 803D at my dealer with the intention of buying the 803D. I found the 802D to more open and more clarity than the 803D. My only concern with both of these full range speakers is that the bass sometimes seemed to overshadow the midrange and higher frequencies. This rendered the sound seemingly less immediate and with less clarity as compared to the Signature 805. I mainly listen to Classical music and my room is 16 x 15 with a very high ceiling. I am using a Macintosh MA 6900 integrated amp and Lector CDP 7TL CD player. NBS cabeling throughout.

I would appreciate any comments regarding this comparison, as well as the general comparison of mini monitors vs full range speakers.

Thanks.
