Maddog,
According to B&W's website the sensitivity of those speakers is 88 db and the minimum impedance is 4.7 ohms. It doesn't mention the phase angle or have an impedance curve to make further judgement, but you will likely need a relatively strong tube amp.
However, you said you want to continue to bi-amp. Does that mean putting the Rotel on the bottom and using the tube amp for the highs? If so, the situation changes.
A couple choices in the $2K range that would be able to drive the speakers by themselves would be the Cary V12, Audio Research VT-100 (prob only the Mk 1 under $2K), Rogue Stereo 90, and Jolida 502P.
What kind of sonic change are you looking for?
Michael
