Maybe going with Sim separate component is a good idea. All I know is Wind is a very, very, very demanding speaker. They require tons of power to sing well.
Or you could email Vince at Totem. He designs the speakers and he could recommend a few amps that could sufficiently drive the Wind. But tell him up front that your budget is $10K or less, he tends to recommend pricey amps...:-))
Good luck
