Rotel 1091 500 watt monos ok for B&W 802ds?

Right now I have The Rotel 1091s driving my B&W 804s's (1 mono per speaker). At 500 watts apiece, the 1091s seem to have plenty of power for the 804s, but I'm considering buying a set of the newly released 802Ds and am wondering if the Rotels will be sufficient. I'm guessing they'll have enough raw power, but I'm not certain they'll bring the full musical potential out of the 802Ds. The 802Ds I listened to were being driven by a Classe amp (not sure which model, but not monos) at I believe the guy said either 200 or 250 watts per channel, with no sub, and they were simply phenomenal. They were so phenomenal that I instantly wanted to buy a pair but thought I'd better do my due diligence first as to whether my system could reproduce what I heard in the showroom, and, if not, what would be needed to get that sound. On the one hand, I'm pushing the limits of budgetary reason in springing for the speakers alone, so being able to use what I already have would of course be a plus. On the other hand, I love the speakers and want to do right by them, so, as the saying goes, in for a dime, in for a few grand. Any advice would be greatly appreciated.
