I am on first set up here so a bit naive .... I have an Onkyo 609 and am trying to decide on the best set of speakers to go with it. 50% music, 50% movies .... and in an open plan setting 10m front to back with seating 4m from front. Rears will need to be high up on top of kitchen units. Want to be able to run at low volumes as well as high. I am drawn to B&W 685 set (with possible upgrade to 610 sub) and Monitor Audio Radius HD set (2x270, 1x250, 2x90 and the 370 sub). Just looking for thoughts/opinions and recommendations from everyone to help me decide. Thanks in advance for replies.
