Might be late to the party here but OP how handy would you say you are? I ask this because if you are handy then might I suggest building a few Hypex NCore Amps for your setup.
For the price range your shopping in you could build x 4 NCore MonoBlocs to make those B&W's sing like a champ.
I myself have x 4 of these recommend amps powering my B&W 803diamonds and they sound impressive with this much power. I've got x 1 MonoBloc powering each half of each speaker channel and they sound effortless at all volume levels.
One big added bonus to such a configuration is that you can run very short speaker cables (mine are only 2ft) to each cabinet since the amps sit nicely behind each cabinet.
I don't think you will be disappointed doing the same
