Just my two cents... I own a more recent set of Klipsch speakers (RF 3-2's), and I love them... they started me into my current love and hobby of good audio. I find them to be very clean and clear... I tend to hear nuances that I've never heard before, or ever on other systems. They are extremely good at vocal performances and any music with a lot of brass (Any opera is amazing through these...) what else... All I can say is I love them. My friends love them. My Parents love them (and they don't even care about this sort of thing...) They have caused dinner conversations in another room to Stop as people listen to the sound coming from them...
Now, all that being said, don't go for the lower level speakers... their ref line is what you want. and personally, I think you want their floor towers... Good luck and let us know what happens!
