B&W 685 or Dali Zensor 1, which would you choose?

These bookshelf speakers are at the top of my list as possible replacements for my Mirage OMD-5's in my current setup, which would you take if you had the choice? I'm looking to spend less than $500 and both of these can be found new or used within my budget.
(my setup is currently a 5.1 with Mirage OMD-5 and OMD C1 as fronts/Center, Nanosat's are rears, velodyne sub, Onkyo AVR which i will be upgrading soon, in a 13' x 15' room)

I would take the DALI.

I have not had a chance to hear the Dali's but they obviously have received many good reviews.

I also have the chance to pick up a pair of Martin Logan LX16 for a very good price…i have heard the Motion 15 which are the same and i thought they were one of the better speakers in the room.
