The question "The Acoustat Delema"

I have just finished a complete retrofit of a set of Acoustat model 2+2 (yea, the eight footers !) What would be the ideal amp/amps to run these wonderful, beautiful, most ineffieceient, low impedence, power hungry ....I think you get the point? With the remodel they are quiet attractive ! but them so are some of the prices on the amplifiers that ARE STABLE ENOUGH TO RUN THEM!
