Amp/preamp combo for B&W Matrix 801's

I use to sell the first generation 801s. I wish we had the amps available then we do now. They like a lot of power, I have a Musical Fidelity M3 NuVista that would work well, as would the other big amps in their line. I would look for a high dampening factor as well as high power, I don't think that these are the best speakers for tubes. Room size is also a consideration , as well as your preferred listening level and choice of music.

I vote for Mcintosh MC402 + C2300

Thanks for the suggestions. I've heard elsewhere to stay away from tubes with the 801's. I've been looking at Mcintosh's and Conrad Johnson but will also put Musical Fidelity M3 NuVista on my list...Is there a minimum watts/channel I should consider?
