I have used a variety of Klipsch speakers from the KG5.5, RF series, and Khorns. My current analog speakers are a pair of Audio Physics Caldera II. I have never used any of the elite horn loaded speakers so my horn experience is strictly Klipsch. My favorite is the Klipschorn but i preface this with an understanding the room and placement of the Khorns is critical and bad placement makes them pretty useless particularly with Bass extension. I have heard that they do not mate well with SS components but i have used them with Pass Labs equipment and my older system which was a Marantz SR9300. I have heard my speakers with a loaner Jolida tube system and it was very pleasant, but did not go with it. i have never heard the Khorns with a SET setup and i understand they shine with the low wattage SET systems. However, i found, properly set up, they are excellent speakers who do not require a lot power to fill a room with sound. The balance between bass, midrange and highs are good depending on the music and i find acoustic or strings sound superb with the khorns.
The KG5.5 are the heart of my home theater with the center and fronts using them with rears and sides using rs3 speakers. They work well for home theater
Comparing the Khorns to the AudioPhysics Caldera II, i prefer the Caldera speakers as they are easier to set up and the sound quality is comparable if not better than the Khorns. However, the Caldera are not as efficient hence required an amp upgrade to get the best out of them
