well imo the consideration should be what are you going to do about the center channel? Timbre matching is going to be important. I ran a non matching center with mine for a short period, and while things were passable, the difference with the timbre match lcr was night and day. The surrounds, unless your die hard sacd, dva, dts cd fan and listen to opera, shouldnt be a problem. The speakers play fairly high spleffeciently, but consider a 130wplus amp section, thats 4ohm stable.
