I am trying to decide between the Revel M20, B&W 805 and Monitor Audio GR 10. I have been unable to listen to them side by side, and am having a very difficult time selecting. I am looking for a speaker that is not too picky about placement and performs relatively well off-axis. Any insight into these three would be much appreciated - I am also looking for a good amp to match and am considering Proceed, Anthem and Bryston. Thanks.
