To much wattage for B & W 805s ??

After hearing the new 805S I'm thinking of purchasing. My problem is that I just bought a Madrigal Proceed HPA-2 (250wpc that doubles to 500wpc).. 0.1% THD) The B&W brochure advises using no more than a 120wpc amp. I rarely, if ever go near 11 o'clock on my volume setting. I have not yet sold my BPA-2 (125wpc) but would of course prefer to use the bigger amp. With all the dynamics in classical music would I have to worry about damaging the speakers. Would it be recommended I use the smaller amp and stay within B&W's guidelines. I would really appreciate your advice. Thank you! (and I apologize if this has been discussed, but I couldn't find it in another thread.)
