I don't know how much help I can be since I haven't heard all the choices. I have heard the Phil 2's. To me, they sound very "live". I guess that means instruments sound very realistic,especially with percussion. I was really surprised by their performance considering the original price.
I also liked quite a few things about the Sierras with the RAAL. I thought they projected a very enveloping soundstage and had very smooth highs. Pretty well balanced if I remember correctly.
I've had mixed feeling with the 800 series B&W's. The first two times I heard them at a dealer they sounded harsh when the volume was turned up. I know, not what most people say. I think they were early versions. I heard them again at a different dealer and really liked what they did. The third time there was quite a bit of clean bass and the highs were very smooth and detailed. I'm not a fan of the look though.
No experience with the other two choices. Personal preference being what it is, I'd give the advice that pops up frequently: Audition them all if possible. If I had to choose, I'd go with the Phils or Sierras out of the speakers I've heard from the list mainly because they are in my price range and I think they offer more value for the $. Just my humble opinion.
