Paul, welcome. Even someone who has experience with that particular Klipsch system could only speak of their results in their own listening room and with other relevant factors. It would be essentially impossible to give a precise "how big a difference" answer, but I can certainly testify to the excellence of my M22s(the W22s are said to be essentially equal in performance)and can't imagine that you wouldn't be thrilled with the performance.

Enjoy the music, not the equipment.
