When I bought my Klipsch reference speakers a while back I looked at the Polk and Mirgae competitors. I really loved the sound stage of the Mirage, but the low end sucked and in a small room there would be no directionality. The Polk were nice speakers but the center channel always sounded like a wet towel was muffling the sound. Also I just love the clarity of Klipsch. Some people find Klipsch too bright or harsh, but I find then extremely clean. They are also extremely efficient so you don't need much power to get good sound out of them.
