Magfan, I haven't owned a B&W since they went toward metal dome tweeters, and I don't keep up with them to much anymore. I'm just thinking it is hard to put a set figure with too many variables. These three speakers will give totally different results on a tube amp vs. a solid state in my opinion. The OP's amp is a 5 channel, and probably can't give a linear output across all frequencies like a potent solid state one or two channel can. I do remember the killer Apogees and Infinity Kappas.
One odd thing that I can never figure out is, a knowledgeable person that may be a manufacturer (speaker?) that posts (or used to) here sometimes said that when you bi-amp, the load is divided equally on the speaker inputs when their post separated. This was in the past few years. I don't recall who it was, but that never quite made sense to me. I looked at some old forums and can't find it, and may be gone. Oh well. I do think the impedance can be divided more closely between the highs and lows on a close to linear speaker like a Magneplanar though.
