Stereobob

I'm currently looking to buy a new pair of main/front floorstanding speakers to replace an old pair (15 years) of Infinity Reference 6's. I have listened to approx 20 different speakers in the last few weeks, (Polk, Definitive Tech., Paradigm, KEF, PSB, etc) and find myself comparing everything to the new F-30's and RF-82 II's. My speakers are use probably 75% of the time for stereo. I would appreciate hearing from some of you Klipsch owners re the two models mentioned. Is the RF-82 much different than the F-30? What's the best center speaker for each one? Thanks!
