Your naivety is revealed by your statement that these speakers "run at" any particular power level.
What kind of power they need will depend on your room dimensions, furnishings and your preferred listening levels. I would certainly not recommend less than 200wpc for them but how much more cannot be determined without more information.
Note, too, that you do not need to use a pre/pro from the same manufacturer as the power amp(s). To choose the former, again, you need to provide more information about a sources and applications.
