If you are really tempted by the B&Ws ensure you have sufficient space in your room. They have a very big sound and require a lot of space around them to work properly. I suggest a minimum of 2 feet all the way around to the nearest room boundary. I liked the 703s very much, but they are not a big seller for B&W even though they are so well built. I suspect it's because of the space requirements.
I don't know the other speakers well enough to comment on them.
Other options at similar prices to these (in the UK) which are worth a look - Totem Hawks, Dynaudio FOCUS 220, Wilson benesch Square Two, PMC FB1+.
