The 402 is supposed to be a little faster - like the 602 from what I hear - but I'd say that it will still have McIntosh sound (hopefully). My buddy loves his Thiels but he complains about how each inch he moves them, the sound changes (he uses McIntosh MC300 amp). You may want to experiment with yours. His bass changes drastically with placement. I have heard the 6900 shake walls (on Dynaudio speakers - forgot the model but they were really big) so you may simply have a suckout problem. good luck.
