From B&W 801D to Dynaudio evidence temptation?

I currently have the B&W 801D with krell fpb700cx, jadis jps2 pre in a 18ft x 28ft room with 9 ft ceiling. Im happy with the sound, But now i am being offered a reasonably priced 14 year old dynaudio evidence temptation, i have dreamed about this speaker since its launch, should i take the plunge? I realize the temptations and the 801d has different sound character, maybe the b&w has more solid and low bass, while the temptation might have better midrange and vocal clarity.

can anyone comment on this situation? Im losing sleep over this, maybe il just keep the b&w and have both? Which is crazy, and bot can be very very hard to move... 

Appreciate all response..
