I KAiN64!
I had the "KEF ref2.2" they are 91 db and they were the best speakers i had in my home...before i listen the KLIPSCH speakers.(I had some GENESIS VI, HALES concept 2, TRIANGLE Antal JEAN MARIE REYNAUD Offrande, KEF ref 2.2 and listen a lot more.)
the sound with KLIPSCH is more rich and more vivid.(it's easy to move the speakers when they have high sensitivity!)
The KEF, compare to the other low sensitivity speakers are very good. "B&W" and "PARADIGM" are very good too!...but the problem with this speakers is that they need power and MONEY! Because powerful Amp are more expensive, and even with the best amplifier, the cones, wich have low sensitivity, move more, and it's not good. And plus, they have more distortion because they move more, and plus,(sorry for my bad english)they can't be as precise as the horn because they move more, and plus, they don't move as fast as the horn(because they move more...)and PLUS, and that all, they play louder for the same Watt you put on them.
I live in Europe, and they only know about low sensitivity speakers, and people don't know what they miss.
High sensitivity = "REAL" High fidelity
KAiN64, stay with your futur "RF7", you are right!(did you think about heritage line???......)
