Hello.
Just a second opinion. There are a few alternatives which will hammer both of these fine speakers and will cost less or outperform both.
I am a dealer for Escalante Designs. Escalante was started by Terry Budge, who was the lead designer for both Wilson and Talon. They make a $13,000 subwoofer and stand mounted monitor that competes with and betters the WP 7! In a recent review this system was compared to a $30,000.00 Kharma rig and was considered in the same class! Escalantes are like Wilson's huge dyanmics, extremly low bass down to 16hz! and will play at ridiculous volume levels!
Also have you considered the USHER speakers? The new BE 20 will also destroy both the WP 7 and any B&W. The technology behind the Usher's is far superior to what many companies are offering, Ie pure Beryillium midrange driver and pure Beryillium tweeter. These speakers are in the Avalon Eidilon Diamond class yet sell for half of what that speaker sells for.
Also the Dali Euphonia's are terrific speakers which lean towards speed in the bass and a midrange liquidity too die for!
I have been doing this for tweenty years, many audiophiles buy into the hype that runs many of the biggest high end products, if you know where to look you can get fantastic sound for less!
